  • Peristaltic radiative flow of sisko nanomaterial with entropy generation and modified darcy s law
    Journal of Thermal Analysis and Calorimetry, 2020
    Co-Authors: Tasawar Hayat, Bilal Ahmed, F M Abbasi, A Alsaedi
    Abstract:

    Nanomaterials are quite significant in the physiological and engineering processes. Such materials have motivated the recent scientists in view of their enhanced thermophysical characteristics than conventional liquids. With this in mind, the intention here is to address the Peristaltic Activity of Sisko nano-liquid subject to Hall and Ohmic heating effects. Fluid-saturated porous space is modeled using the modified Darcy’s law. Thermal radiation is also accounted. In addition, the analysis carried out is subject to thermal jump, velocity slip and zero mass flux condition. Numerical solution to the resulting nonlinear problem through the lubrication approach is developed. Solution analysis is made by pointing out the impacts of sundry variables. The temperature profile increases by increasing the Hartman number due to the Joule heating effect. However, temperature decreases by increasing the Hall parameter.

  • Entropy optimization for peristalsis of Rabinowitsch nanomaterial
    Applied Nanoscience, 2020
    Co-Authors: Tasawar Hayat, Ahmed Alsaedi, Sadaf Nawaz, Habib M. Fardoun
    Abstract:

    This work models new formulation for Peristaltic Activity of Rabinowitsch material in a compliant walls channel. Energy equation is accounted in the presence of viscous dissipation and heat source/sink. Chemical reaction is included in concentration expression. Nanomaterial characteristics are due to Brownian motion and thermophoresis. Slip condition is utilized for velocity, temperature and concentration. Exact solution is obtained for velocity. Further NDSolve is utilized for the graphical analysis of temperature, concentration, entropy and heat transfer coefficient at the wall. Results are also analyzed for viscous, shear thickening and shear thinning fluids. This study reveals the results that the shear thinning fluids move with greater velocity than the viscous and shear thickening fluids. Similarly, temperature and entropy generation also has higher values for shear thinning case when compared with others. Further heat source parameter enhances the temperature, whereas sink parameter leads to decay. Slip parameter for velocity and temperature caused an increase in the respective velocity and temperature. Moreover, chemical reaction parameter leads to enhancement in temperature and entropy generation in case of viscous, shear thickening and shear thinning fluids. However, shear thinning fluids are found prominent.

  • heat transfer analysis on Peristaltic transport of ree eyring fluid in rotating frame
    Chinese Journal of Physics, 2017
    Co-Authors: Tasawar Hayat, A Alsaedi, Hina Zahir, Bashir Ahmad
    Abstract:

    Abstract This paper introduces the Peristaltic Activity of Ree-Eyring fluid in a rotating frame. Heat transfer analysis with viscous dissipation and heat source/sink is taken into account. Convective conditions of heat transfer in the formulation are adopted. Closed form solutions for axial and secondary velocities, pressure rise per wavelength, flow rate due to secondary flow and temperature are obtained by considering small Reynolds number and long wavelength. The variations for different physical parameters are shown through graphical illustrations. This study reveals that influence of rotation parameter causes significant fluctuations in axial and secondary velocities. It is important to note that pressure rise reduces for larger rotation parameter. Variation in secondary velocity for fluid and rotation parameters is quite opposite. An increase in fluid and rotation parameters shows opposite behavior in the size of trapped bolus. It is also found that presence of non-uniform heat source in energy equation causes enhancement in rate of heat transfer coefficient. Comparison is made with results obtained in presence and absence of rotation.

  • Peristaltic Activity of blood titanium nanofluid subject to endoscope and entropy generation
    Journal of The Brazilian Society of Mechanical Sciences and Engineering, 2018
    Co-Authors: Tasawar Hayat, Ahmed Alsaedi, Sadaf Nawaz, Bashir Ahmad
    Abstract:

    Entropy generation and endoscopic effects on peristalsis of nanofluid are addressed. Inner tube is taken rigid, while sinusoidal wave travels along the outer tube. Blood is used as the base fluid, whereas titanium is considered as nanoparticle. Maxwell model of effective thermal conductivity is utilized. Velocity and thermal slip conditions are imposed at outer tube. Moreover, the walls of tubes are complaint in nature. Viscous dissipation is also utilized. Long wavelength and small Reynolds number consideration is employed. Series solutions are obtained for small Grashof number. Analysis is carried out for physical parameters on velocity, temperature, entropy generation and Bejan number. Heat transfer rate at wall is also analyzed via bar charts for different pertinent parameters. Results reveal that an enhancement in nanomaterial volume fraction causes decay in temperature and velocity, whereas it leads to increase the heat transfer rate at the wall. Grashof number causes an enhancement in velocity and temperature. The study also declared that elastance coefficients of walls lead to enhancement, whereas damping coefficient results in decay of velocity, temperature and entropy generation.

  • Bronchial Muscle Peristaltic Activity in the Fetal Rat
    Pediatric Research, 2006
    Co-Authors: Omar Parvez, Anne-marie Voss, Mascha De Kok, Matthias Roth-kleiner, Jaques Belik
    Abstract:

    Aside for the potential for tonic contraction, the airway smooth muscle exhibits intermittent phasic rhythmic Activity that may contribute to lung growth during fetal life. Therefore, we examined 4th generation rat 18–22 d gestation fetal, 4–6 d of age newborn and adult bronchial ring from Sprague Dawley rats to compare differences in smooth muscle function. We hypothesized that phasic contractions were greatest before birth. Bronchial muscle spontaneous rhythmic contractions were greatest in the fetus and absent in the adult. In response to KCl stimulation, the fetal bronchial smooth muscle only developed tonic force that was 3.5 ± 0.6 and lower than measured in the newborn 9.0 ± 0.3 and adult 13.7 ± 1.4mN/mm^2. The thromboxane A_2 analogue U46619 induced tonic and phasic muscle contractions and the amplitude and frequency of the phasic contractions were greater in the fetus as compared with the adult and increased with gestational age. The U46619-induced rhythmic contractions were abrogated by ryanodine, thapsigargin and reduction of extracellular Na^+, suggesting intracellular Ca^2+ dependence and involvement of the Na^+/Ca^2+ exchanger. The inward rectifier K^+ blocker BaCl_2 induced phasic contractions in unstimulated fetal, but not adult bronchial muscle of the same amplitude and frequency as for the spontaneous and U46619-induced ones. We conclude that the airway smooth muscle phasic Activity is greatest in the fetus and tends to disappear post-natally with age suggesting an in utero role during lung development.

    Co-Authors: Anum Tanveer, Mair Khan, T Salahuddin, M Y Malik, Farzana Khan
    Abstract:

    Abstract Objective:The flow kinetics generated with a pulsatile wave that travel along the channel has prime relevance in various processes in physiology and industry. The aim here is to investigate such phenomenon with Bingham fluid with chemically reacting species in terms of their homogeneous and heterogeneous characteristics. Method: To formulate the mathematical descriptions Bingham fluid with heat and mass equations is accounted. Using the similarity solutions, the proposed leading partial differential equations of the flow phenomena transferred into the nonlinear ordinary differential equations and boundary conditions are solved analytically. Such considerations perceive prime importance in medicine and genetics where heterogeneity in a cell makes several diseases difficult to execute. Results: Further the physical aspect of human tabular organs i.e., porosity in a medium is retained in the analysis. The utility of magnetic field in reference to medicine is employed. The walls are considered flexible. The whole problem is set to lubrication approach for simplification of resulting system. The attained results are tested on physical grounds by plotting graphs. Conclusion: It is analyzed that the Hartman number and porosity parameter reduce the velocity and temperature profiles. The elastic wall parameters E1 and E2 enhances both the velocity and temperature fields while E3 enrolls an adverse effect.

    International Journal of Heat and Mass Transfer, 2017
    Co-Authors: Anum Tanveer, Tasawar Hayat, Aqsa Saleem, Fuad E Alsaadi
    Abstract:

    Abstract Main theme of present article is to investigate the Peristaltic Activity of MHD flow of Williamson nanofluid saturating porous space. Inner tube is fixed while the outer tube is subjected to sinusoidal traveling wave. Unlike the traditional approach, modified Darcy’s law characterizes the flow of Williamson fluid. Both tubes with reference to blood arterial flow are considered flexible. No-slip condition for velocity is employed. Convective conditions of heat and mass transfer are invoked. Nanofluid flow using Buongiorno model that considers the effects of both Brownian motion parameter and thermophoresis parameter are also under consideration. The nonlinear differential systems are reduced for large wavelength analysis. Numerical study is performed for the resulting problems. Impacts of various emerging parameters for velocity, temperature, nanoparticle volume fraction and heat transfer rate are examined. A comparative study reveals good agreement with existing limiting study.

Influences of thermal radiation and Joule heating are retained. The problems corresponding to large wavelength and small Reynolds number are numerically solved. Results for velocity, temperature and heat transfer coefficient are particularly emphasized. Main findings are concluded. A comparison of the present results with those already available in the limiting sense is shown and discussed.

    Co-Authors: Anum Tanveer, Tasawar Hayat, A Alsaedi, Sadia Ayub, Bashir Ahmad
    Abstract:

    Abstract The current work examines the Peristaltic flow of Sutterby fluid in a planar symmetric channel. Electrically conducting fluid is considered via imposed magnetic field. An incompressible Sutterby fluid saturates the porous medium. Modified Darcy’s law has been employed for the porous medium effect. The channel walls are compliant. Convective conditions of heat and mass transfer are imposed. Viscous dissipation and Joule heating are retained. Problem for large wavelength are numerically solved. The graphs are obtained for the velocity, temperature, concentration and heat transfer rate. Velocity and concentration profiles are observed to have opposite behavior for increasing Darcy number. It is found that the effect of Hartman number on the velocity and temperature profiles is similar. Further heat transfer coefficient strengthened when heat transfer Biot number is increased.
