A study on visco elastic fluid flow And heat transfer over a Stretching sheet

Abstract

newlineThis thesis aims at investigating through mathematical analysis the newlineeffects of various parameters on the flow velocity and temperature variations newlinewithin the boundary layer formed in a visco elastic fluid Walters Liquid B newlinemodel as a hot stretching sheet passes through it This subject has direct newlineapplications in a number of industries one of which involves polymer newlineextrusion processes to which this study directly relates newlineChapter 1 gives a critical review of the existing literature on the newlinesubject matter This has given the motivation for doing further work in this newlinearea and defines the scope of this research work Typical problems have been newlineidentified to represent various parameters that are proposed to be studied in newlinestages for their effect on the end result newlineIn the first problem chapter 2 the magnetohydrodynamic MHD newlineflow and heat transfer characteristics are studied in a porous medium past a newlinestretching sheet For the heat transfer problem two particular cases are newlineidentified for study namely the Prescribed Surface Temperature PST case newlineand Prescribed Heat Flux PHF case These two cases are considered further newlinewhile dealing with the heat transfer problem in the subsequent chapters as newlinewell The partial differential equations governing the fluid flow in the newlineboundary layer along with the appropriate boundary conditions are first newlinetransformed into a set of non linear ordinary differential equations using newlinesuitable similarity transformations newline
