A Study of Magnetohydrodynamic Flow and Heat Transfer Along a Smooth Surface

Abstract

The present thesis entitled A Study of Magnetohydrodynamic Flow and Heat Transfer Along a Smooth Surface is devoted towards the numerical investigation of the hydromagnetic and#64258;ow and heat transfer of a viscous incompressible electrically conducting and#64258;uid along a stretching surface under the considering diand#64256;erent aspects and conditions. The thesis is divided into seven chapters in which Chapter 1 is introductory. Chapter 2 presents the study of the magnetohydrodynamic boundary layer threedimensional transient and#64258;ow of a Casson and#64258;uid along a stretching surface. The eand#64256;ects of Hall current and nonlinear radiation are taken into account. The model discussed in Chapter 2 is extended in Chapter 3 including the presence of Darcy porous medium and convective heat transfer at the surface. In Chapter 3,anumericalanalysisispresented to investigate the eand#64256;ects of Hall current and radiative heat transfer on the unsteady three-dimensional magnetohydrodynamic and#64258;ow of a Casson and#64258;uid and#64258;owing over a stretching surface with convective boundary conditions in a porous medium. Chapter 4 is devoted to investigating the two-dimensional transient two-phase and#64258;ow of a couple-stress dusty and#64258;uid along a porous surface in the presence of a magnetic and#64257;eld. Moreover, the heat transfer phenomenon is investigated under heat source/sink and viscous dissipation eand#64256;ects. An entropy generation analysis is carried out in Chapter 5 on the hydromagnetic three-dimensional stagnation point and#64258;ow of a Casson and#64258;uid along a stretching surface under the eand#64256;ects of viscous dissipation, Hall current, and radiation. Chapter 6 deals with the study of the magnetohydrodynamic two-dimensional and#64258;ow of a viscous and#64258;uid along a curved stretching sheet in a non-Darcy porous medium under the inand#64258;uence of thermal radiation. The physical models of the diand#64256;erent problems considered in the thesis include nonlinear radiative heat transfer, non-uniform heat generation/absorption, convective heating, Hall current, and viscous dissipation eand#64256;ects. In order to investigate the eand#64256;ects of the pertinent and#64258;ow
