Some problems of viscous and viscoelastic boundary layer fluids over stretching Shrinking sheet in presence of non uniform heat source

Abstract

The present thesis explores investigation of boundary layer flow and heat transfer with the presence of MHD for non-Newtonian fluids under different physical and thermal boundary conditions was the focus of this study. Boundary layer flow and heat transfer have both been studied and drew the attention of several researchers due to its wide range of applications branches of science and technology. It has numerous applications, including cooling of Irrigation, nuclear reactors, polymer sheet extraction, glass fibre production metal working processes, MHD generators, heat ex-changers, bio micro systems paper and textile industries, as well as the petroleum oil recovery process industry, and so on. newlineIn first and second chapter presents introduction and basic equation. newlineThird Chapter, newlineExplores MHD boundary layer flow of an incompressible in the form of UCM (upper convected Maxwell fluid) across a permeable horizontal moving plate in account of non-uniform heat source. In the current presents all the parameters for PST and PHF cases. An increasing in Pr declines the thermal parameter for both scenarios. The obtained results have been compared with previous published papers. newlineFourth Chapter, newlineThe movement of the Casson thin liquid film fluid with thermal conduction, impacting radiant heat, with non-uniform heat source/sink has been investigated in the present document above the time-dependent stretching plane. The effect of skin friction and the Nusslet number on the mobility of the lean film has been discussed numerically. Physical parameters such as Pr, S, Tr, M, and the Casson fluid parameter have also been focused on graphically. newlineFifth Chapter newlineAnalyzed MHD Casson nano fluid in account of viscous dissipation and non-uniform heat source. The influence of velocity and temperature factors, such as quotCasson quot, quotmagnetic, porosity,quot quotEcquot,quot Non-uniform heat source/ sink,quot quotPr,quot skin friction coefficient, and Nusselt number on the flow field, have been examined numerically and visually depicted. newlineSixth Chapter, newlineMHD surrounded by
