Thermal Characteristics of MHD Pulsating Flow of Immiscible Fluids in a Channel With a Porous Space

Abstract

The main objective of the present thesis is to mathematically model and examine the char- newlineacteristics of the flow behavior of immiscible liquids in a channel with porous space. Such newlinestudies can be helpful in a variety of fields, which includes chemical engineering, environ- newlinemental monitoring, biomedical engineering, material processing, and the oil and gas industry. newlineThe opening Chapter 1 of the thesis is introductory in nature covering the basic concepts. newlineChapter 2 deals with the pulsating MHD flow of two immiscible conducting incompress- newlineible viscous fluids in a channel filled with a porous medium, accounting for the thermal radia- newlinetion effect. The MHD oscillatory flow of two immiscible, viscous liquids in a porous channel newlinewith heat transfer is investigated in Chapter 3. Chapter 4 addresses the combined effects newlineof Hall current, thermal radiation, heat source, and chemical reaction on heat and mass char- newlineacteristics in a vertical porous channel filled with a two-layered viscoelastic liquid under the newlineinfluence of an oscillatory pressure gradient. The investigation pertaining to the effects of newlineshape factor nanoparticles on the oscillatory MHD flow of a nanofluid in two immiscible liq- newlineuids in a horizontal porous channel with velocity and thermal slip on the walls is explored newlinein Chapter 5. Thermal radiation, Joule heating, viscous and Darcy dissipations have been newlineaccounted for in the model. Chapter 6 deals with the unsteady two-dimensional MHD free newlineconvective flow of Casson fluid over a vertical porous channel in two immiscible flows is elu- newlinecidated numerically. The concluding remarks and scope for future work are given in Chapter7. newlineThe influence of various araising parameters, in the mathematical models that have been newlinedeveloped, on the distribution of the velocity, temperature, concentration, rate of heat transfer, newlinerate of mass transfer, flow rate, and shear stress at the walls have been discussed in detail. To validate the analytical results, a comparative study is performed with the results obtained by shootin
