Investigation of stretching sheet problems in Non Newtonian Liquids

Abstract

newline In this thesis, we have considered the Investigation of Stretching Sheet Problems in Non-Newtonian Liquids. This thesis consists of six chapters. Among this non-Newtonian Casson fluid model and various flow conditions such as prescribed wall temperature (PWT), prescribed heat flux (PHF), convective conditions, partial slip, and nonlinear convection, etc. We considered the Brownian motion, thermophoresis, Ferro-magnetic interaction, magnetic dipole, and Cattaneo-Christov heat flux model. newlineIn Chapter 2, The current article discusses the heat transfer characteristics of ferromagnetic liquid over an elastic surface with radiation and non-Fourier heat flux. In most of the existing studies, the heat flux is considered constant, but whereas we incorporated the non-Fourier flux to get the exact performance of the flow. Also, excluded the PWT and PHF cases to control the boundary layer of the flow. The governing equations related to our contemplate are changed into non-linear ordinary differential equations (ODE s) by utilizing appropriate similarity changes, which are at the point enlightened by the Runge-Kutta based shooting approach. The equations are broke down with respect to boundary conditions and to be explained prescribed wall temperature (PWT) and prescribed heat flux (PHF) cases. The impacts of diverse non-dimensional physical parameters on velocity and temperature profiles are laid out graphically. Also, The assortment of Skin friction and local Nusselt number for both PWT and PHF cases for various assessments of non-dimensional parameters have been sorted out. Towards the wrap-up of the examination, we suspect that the friction factor coefficient is higher in the PWT case compared to the PHF case. This result helps to conclude that the flux conditions are useful for cooling applications. newline In Chapter 3, The boundary layer flow and heat transfer of a ferromagnetic liquid over an elastic convectively heated stretching surface is numerically studied. A partial Casson slip is consi
