  • Heat transfer in a viscoelastic boundary layer flow over a stretching sheet with viscous dissipation and non-uniform heat source
    International Journal of Heat and Mass Transfer, 2020
    Co-Authors: M. Subhas Abel, Pradeep G. Siddheshwar, Mahantesh M. Nandeppanavar
    Abstract:

    In this paper, visco-elastic boundary layer flow and heat transfer over a stretching sheet in presence of viscous dissipation and non-uniform heat source have been discussed. Analytical solutions of highly non-Linear Momentum Equation and confluent hypergeometric similarity solution of heat transfer Equations are obtained. Here two types of different heating processes are considered namely (i) prescribed surface temperature (PST) and (ii) prescribed wall heat flux (PHF). The effect of various parameters like visco-elastic parameter, Eckert number, Prandtl number, and non-uniform heat source/sink parameter on temperature distribution are analyzed and effect of all these parameters on wall temperature gradient and wall temperature are tabulated and discussed. © 2006 Elsevier Ltd.

  • Oxford Scholarship Online - Engineering applications of the Linear Momentum Equation
    Oxford Scholarship Online, 2018
    Co-Authors: Marcel Escudier
    Abstract:

    In this chapter a method is shown for applying the Linear Momentum Equation, together with the continuity Equation and either Bernoulli’s Equation or some other information about static pressure, to the analysis of a diverse range of practical problems. A key aim is to demonstrate that it is possible to establish a relatively simple theoretical basis which can give quite accurate and useful information about the performance of such complex machines as jet and rocket engines, the jet pump, and the Pelton turbine. Other examples include flow through a sudden enlargement, a convergent nozzle, a pipe bend, a pipe junction, and a cascade of guidevanes. For each example it is shown how to define a suitable control volume.

  • Oxford Scholarship Online - Linear Momentum Equation and hydrodynamic forces
    Oxford Scholarship Online, 2018
    Co-Authors: Marcel Escudier
    Abstract:

    In this chapter a method is shown for calculating the external reaction force which must be applied to a duct to counteract the hydrodynamic forces generated by a fluid flowing through it. Newton’s second law of motion applied to fluid flow through a duct of arbitrary shape leads to the Linear Momentum Equation for fluid flow. This shows that the change in the Momentum flowrate of the fluid is equal to the net force exerted on the fluid. The individual forces which contribute to the net force are the pressure forces at inlet and outlet, and the forces which arise due to the static pressure and shear stress distributed over the wetted interior surface of the duct. The condition of static equilibrium for the duct is used to relate the external restraining force to the force exerted by the flowing fluid on the wetted surface, which is termed the fluid-structure interaction force.

  • Transient Pig Motion Through Gas and Liquid Pipelines
    Journal of Energy Resources Technology, 2001
    Co-Authors: Angela O. Nieckele, Arthur M. B. Braga, Lais Farias Azevedo
    Abstract:

    Simulation of the transient motion of pigs through liquid and gas pipelines is presented. The differential form of the mass and Linear Momentum Equations for compressible liquid and gas flows were solved by a finite difference numerical technique. The fluid flow Equations were combined with a Linear Momentum Equation for the pig and a model for bypass flow through the pig. The pig/wall contact forces were simulated by a stick/slip model. The contact forces developed by disk pigs and the pipe wall were predicted by a postbuckling finite element analysis of the discs. Test cases representing typical pigging operations were studied using the numerical model developed. The fluid flow and pig behavior predicted by the model presented a reasonable behavior, and contributed for a better understanding of the pig dynamics through gas and liquid pipelines.

  • MHD Non-Newtonian Power Law Fluid Flow and Heat Transfer Past a Non-Linear Stretching Surface with Thermal Radiation and Viscous Dissipation
    2014
    Co-Authors: Naikoti Kishan, P. Kavitha
    Abstract:

    Non-Newtonian magneto-hydro dynamic boundary layer flow of an electrically conducting power law fluid flowing over a non-Linear stretching surface in the presence of thermal radiation, taking into account the viscous dissipation effects is investigated. By using quasi-Linearization technique first Linearize the non Linear Momentum Equation and then the coupled ordinary differential Equations are solved numerically by an implicit finite difference scheme. The numerical solution is found to be dependent on several governing parameters. A systematic study is carried out to illustrate the effects of various parameters on the fluid velocity and the temperature distribution in the boundary layer through graphs. The results for the local skin-friction coefficient and the local Nusselt number are tabulated and discussed and found to be in good agreement with earlier published results.

  • Effects of viscous dissipation on MHD flow with heat and mass transfer over a stretching surface with heat source, thermal stratification and chemical reaction
    Journal of Naval Architecture and Marine Engineering, 2011
    Co-Authors: Naikoti Kishan, P. Amrutha
    Abstract:

    This paper deals with the study of nonLinear MHD flow, with heat and mass transfer characteristics of an incompressible, viscous, electrically conducting and Boussinesq fluid on a vertical stretching surface with thermal stratification and chemical reaction by taking in to account the viscous dissipation effects. Adopting the similarity transformation, governing nonLinear partial differential Equations of the problem are transformed to nonLinear ordinary differential Equations. The Quasi-Linearization technique is used for the non-Linear Momentum Equation and then the numerical solution of the problem is derived using implicit finite difference technique, for different values of the dimensionless parameters. The numerical values obtained for velocity profiles, temperature profiles and concentration profiles are represent graphically in figures. The results obtained show that the flow field is influenced appreciably by the presence of viscous dissipation, thermal stratification, chemical reaction and magnetic field.
