Transient responses of two-dimensional viscoelastic Film Casting processes to sinusoidal disturbances
Korean Journal of Chemical Engineering, 2009Co-Authors: Seung Won Choi, Hyun Wook Jung, Dong-myeong Shin, Joo Sung Lee, Ju Min Kim, Jae Chun HyunAbstract:The sensitivity of two-dimensional isothermal Film Casting processes to ongoing sinusoidal disturbances has been investigated by using the frequency response method with transient simulation techniques. Amplitude ratios of state variables such as cross-sectional area, Film width and Film thickness at the take-up position with respect to a sinusoidal disturbance show resonant peaks along the frequency domain. Effects of operating conditions, such as drawdown ratio and aspect ratio, on the process sensitivity have been examined. Increasing drawdown ratio and decreasing aspect ratio make the system more sensitive to disturbances. Also, the dichotomous behavior in the sensitivity analysis using viscoelastic Phan-Thien and Tanner fluids has been elucidated. This frequency response method can be a useful tool to optimally design process systems for better processability and product quality.

transient and steady state solutions of 2d viscoelastic nonisothermal simulation model of Film Casting process via finite element method
Journal of Rheology, 2007Co-Authors: Dong-myeong Shin, Hyun Wook Jung, Joo Sung Lee, Ju Min Kim, Jae Chun HyunAbstract:The various aspects of the nonlinear dynamics and stability of nonisothermal Film Casting process have been investigated solving a two-dimensional (2D) viscoelastic simulation model equipped with the Phan-Thien-Tanner (PTT) constitutive equation by employing a finite element method. This study represents an extension of the earlier report [Kim, Lee, Shin, Jung, and Hyun, J. Non-Newtonian Fluid Mech. 132, 53–60 (2005)] in that two important points are additionally addressed here on the subject: the nonisothermal nature of the Film Casting, and the differentiation of extension-thickening (strain hardening) and extension-thinning (strain softening) fluids in their different behavior in the Film Casting process. The PTT model, known for its robustness in portraying dynamics in the extensional deformation processes which include the Film Casting of this study along with Film blowing and fiber spinning as well, renders the transient and steady state solutions of the dynamics in the 2D, viscoelastic, nonisothermal, Film Casting capable of explaining the effects of various process and material parameters of the system on the Film dynamics of the process. Especially, the different behavior displayed by two polymer groups, i.e., the extension-thickening low density polyethylene (LDPE) type and the extension-thinning high density polyethylene (HDPE) type, in the Film Casting can be readily explained by the PTT equation-included simulation model. The three nonlinear phenomena commonly observed in Film Casting, i.e., draw resonance oscillation, edge bead, and neck-in, have been successfully delineated in this study using the simulation and experimental results.The various aspects of the nonlinear dynamics and stability of nonisothermal Film Casting process have been investigated solving a two-dimensional (2D) viscoelastic simulation model equipped with the Phan-Thien-Tanner (PTT) constitutive equation by employing a finite element method.

Stability analysis of a three-layer Film Casting process
Korea-australia Rheology Journal, 2007Co-Authors: Dong-myeong Shin, Hyun Wook Jung, Jae Chun HyunAbstract:The co-extrusion of multi-layer Films has been studied with the focus on its process stability. As in the single-layer Film Casting process, the productivity of the industrially important multi-layer Film Casting and the quality of thus produced Films have often been hampered by various instabilities occurring in the process including draw resonance, a supercritical Hopfbifurcation instability, frequently encountered when the draw ratio is raised beyond a certain critical value. In this study, this draw resonance instability along with the neck-in of the Film width has been investigated for a three-layer Film Casting using a varying width non-isothermal 1-D model of the system with Phan-Thien and Tanner (PTT) constitutive equation known for its robustness in portraying extensional deformation processes. The effects of various process conditions, e.g., the aspect ratio, the thickness ratio of the individual Film layers, and cooling of the process, on the stability have been examined through the nonlinear stability analysis.

Transient solutions of dynamics in fiber spinning and Film Casting accompanied by flow-induced crystallization
Journal of Central South University of Technology, 2007Co-Authors: Joo Sung Lee, Dong-myeong Shin, Hyun Wook Jung, Jae Chun HyunAbstract:In the transient solutions of fiber spinning and Film Casting process dynamics accompanied by spinline flow-induced crystallization was investigated incorporating flow-induced crystallization kinetics into the mathematical model of the system and then devised proper numerical schemes to generate the temporal pictures of the system. It turns out that the difficulty obtaining the transient solutions of the processes accompanied by flow-induced crystallization lies in, among these, the extremely high sensitivity of the spinline velocity towards the fluid stress level. The transient solutions thus obtained will be used for developing optimal strategies to enhance the stability and productivity of the processes.

single solvent based Film Casting method for the production of porous polymer Films
Macromolecular Materials and Engineering, 2018Co-Authors: Kazi Zakir M Hossain, Reda M Felfel, Prince S Ogbilikana, Dhruma Thakker, David M Grant, C A Scotchford, Ifty AhmedAbstract:A single solvent based Film Casting process for fabricating porous polymer Films was developed in this study. The porous Film was produced by mixing concentrated polylactic acid/ chloroform solution (20 wt%) and fresh chloroform solvent followed by Film Casting. The average pore sizes of the Films produced were seen to increase from 2.1 (±0.1) µm to 6.4 (±0.2) µm with increasing ratio of concentrated PLA solution and fresh solvent from 1:2 to 1:4. Functional groups of PLA after Casting into porous Film were confirmed via Fourier transform infrared (FTIR) spectroscopy analysis. Cytocompatibility studies (via Alamar Blue assessment) utilising MG-63 cells on the porous PLA Films revealed an increase in cell metabolic activity up to 8 days post-seeding. In addition, these direct cell culture studies showed that the porous membranes supported cell adhesion and growth not only on the surface but also through the porous structures of the membrane, highlighting the suitability of these porous Films in tissue engineering applications.

Flow-Induced Crystallization During Isotactic Polypropylene Film Casting
Polymer Engineering & Science, 2011Co-Authors: Gaetano LambertiAbstract:In this work, a previously proposed model for flow-induced crystallization of polymers was slightly modified and successfully applied in describing Film Casting experiments performed working with isotactic polypropylene. In this process, the melt experiences flowing conditions, during the cooling. The effect of flow on crystallization kinetics was accounted for by the entropic increase of melting point because of the orientation effect of the flow. The orientation of the macromolecules was described by means of a nonlinear dumbbell model, and the entropic shift was calculated on the basis of the rubber elasticity theory. The flow-induced crystallization model, using reasonable values for relaxation time, was proved able to quantitatively predict the enhancement effect of the flow as an increase of spherulite nuclei density and growth rate, in presence of low-level flows (Deborah number

Analysis of Film Casting Process: Effect of Cooling during the Path in Air
Industrial & Engineering Chemistry Research, 2006Co-Authors: Gaetano Lamberti, Giuseppe TitomanlioAbstract:In this work, polymer Film Casting experiments have been performed using commercial isotactic poly(propylene) (iPP), under operating conditions such that the solidification takes place during the path in air. The experiments were carried out with and without the presence of two jets of cooling air impinging on both the sides of the Film. The effects of the cooling air jets on the experimental profiles of the Film width, axial velocity, and temperature are reported and briefly discussed.

Modeling flow induced crystallization in Film Casting of polypropylene
Rheologica Acta, 2004Co-Authors: Giuseppe Titomanlio, Gaetano LambertiAbstract:Data from iPP Film Casting experiments served as a basis to model the effect of flow on polymer crystallization kinetics. These data describe the temperature, width, velocity and crystallinity distributions along the drawing direction under conditions permitting crystallization along the draw length. In order to model the effect of flow on crystallization kinetics, a modification of a previously defined quiescent kinetic model was adopted. This modification consisted in using a higher melting temperature than in the original quiescent model. The reason for the modification was to account for an increase of crystallization temperature due to entropy decrease of the flowing melt. This entropy decrease was calculated from the molecular orientation on the basis of rubber elasticity theory applied to the entangled and elongated melt. The evolution of molecular orientation (elongation) during the Film Casting experiments was calculated using a non-linear dumbbell model which considers the relaxation time, obtained from normal stress difference and viscosity functions, to be a function of the deformation rate. The comparison between experimental distributions and model based crystallinity distributions was satisfactory.

Orientation and crystallinity measurements in Film Casting products
Polymer Bulletin, 2003Co-Authors: Gaetano Lamberti, Vincenzo La Carrubba, Stefano Piccarolo, V BrucatoAbstract:Film Casting experiments were carried out with iPP under processing conditions causing the crystallization process to occur under orienting flow. Draw ratio and cooling rates were changed by varying mass flow rates and die thickness. The effect of processing conditions on Film crystallinity was investigated by combining WAXS and FT-IR transmission methods, while orientation of both phases was measured by IR dichroism (according to Fraser's method) and successfully compared to birefringence measurements on final Films. Crystallinity appears to be almost insensitive to draw ratio and cooling rate. Moreover the crystallinity profile turned out to be also constant along the transverse Film direction. Phases orientation were found relatively low and no dependence on draw ratio was detected.

Nonlinear dynamics and chaotic motion in the isothermal Film Casting process
Korea-Australia Rheology Journal, 2011Co-Authors: Hyun Wook Jung, Joo Sung LeeAbstract:In the industrial Film Casting process with the two-stage cascade (velocity and tension controlled) loop, various aspects of nonlinear dynamics and chaotic motion have been investigated solving simple 1-D viscoelastic model. Most of the extensional deformation processes exhibit sustained-periodic oscillations or stable limit cycles of state variables (called draw resonance instability) beyond the critical onset, even if they are conventionally controlled systems. Besides such well-known instability, some intriguing nonlinear dynamic phenomena such as period-doubling and eventual chaotic motion of Film thickness and width could be observed when a disturbance is imposed in the second tension-controlled system. In other words, the bifurcation mode is dramatically changed by a sinusoidal disturbance under the combined velocity-tension control condition in contrast to only constant take-up velocity condition inducing a supercritical Hopf bifurcation of draw resonance.

Effect of aspect ratio and fluid elasticity on chain orientation in isothermal Film Casting process
Korean Journal of Chemical Engineering, 2010Co-Authors: Joo Sung Lee, Ju Min KimAbstract:The characteristics of extensional flow and the chain orientations of the isothermal Film Casting process utilizing a two-dimensional (2-D) viscoelastic model with finite element methods (FEM) were studied. Steady state and transient solutions were obtained for a relatively large aspect ratio regime by employing successive iterative schemes. In this work, higher aspect ratios of the equipment caused highly oriented molecular structures because the aspect ratio increases as the flow changes from planar to uniaxial extensional flow. Fluid viscoelasticity always alleviated the neckin phenomenon and led to the planar extension regime even if dichotomous behavior was observed for draw resonance in extensional thickening and thinning fluids. Consequently, the change in the characteristic of extensional deformation from uniaxial deformation to the planar extension deteriorated the molecular orientation.

Effect of Activation Energy and Crystallization Kinetics of Polyethylenes on the Stability of Film Casting Processes
Korea-australia Rheology Journal, 2009Co-Authors: Joo Sung Lee, Joon-hee ChoAbstract:Effect of activation energy and crystallization kinetics of polyethylenes (PEs) on the dynamics and stability has been investigated by changing rheological properties and crystallization rate in Film Casting process. The effect of changes of these properties has been shown using a typical example of short-chain branching (SCB) in linear polyethylenes. SCBs in linear polymers generally lead to the increase of the flow activation energy, and to the decrease of the crystallization rate, making polymer viscosity lower in the case of equivalent molecular weight. In general, the increment of the crystallinity of polymers under partially crystallized state helps to enhance the process stability by increasing tension, and lower fluid viscoelasticity possesses the stabilizing effect for linear polymers. It has been found that the fluid viscoelasticity plays a key role in the control of process stability than crystallization kinetics which critically depends on the cooling to stabilize the Film Casting process of short-chain branched polymers operated under the low aspect ratio condition.
