Comparison of Constant and Variable Fluid Properties with Variable Heat Flux over a Sheet for Maxwell Fluid

Abstract

A comparison of constant and variable fluid properties with variable heat flux over a sheet for Maxwell fluidois done in the presence of thermal radiation, magnetic parameter, and thermaloconductivity. The governing partialodifferential equations (PDEs) are converted into a set of associated non-linear ordinary differentialoequations (ODEs), which are then explaine numerically using pertinent boundary conditions for distinct physical parameters by using bvp4c in MATLAB. On the velocity, temperature profiles, as well as the local skin-friction coefficient and the local Nusselt number, the effects of various parameters such as viscosity, thermal conductivity, unsteadiness, Deborah number, thermal radiation, magnetic parameter, and Darcy number are introduced and explained. The numerical results are compared to those previously published. The result show that for both constant and variable fluid propertiesoskin friction coefficient escalate withothe increase in magnetic parameter, unsteadiness parameter,oDarcy number, thermal conductivityoandoDeborah number. Constant fluid properties are independent of heat generation/absortion parameter. For both cases localoNusselt number decreasesowith the increase in magnetic parameter, Deborahonumber, heat generation/ absortion parameter and Darcy number. "
