Mathematical and Computational Analysis of MHD Viscoelastic Fluid Flow and Heat Transfer Over Stretching Surface Embedded in a Saturated Porous Medium

Abstract

AbstractThe study of MHD flow and heat transfer over a stretching sheet in presence of saturated porous media with the effect of space and temperature dependent internal heat source/sink. Two different heating process has been considered namely, Prescribed surface temperature (PST) and Prescribe heat flux (PHF). The nonlinear boundary layer equations of momentum, which are nonlinear partial differential equations are converted into nonlinear ordinary differential equations by means of suitable similarity transformation. Similarly, the heat transfer equations, which are partial differential equations, are converted into ordinary differential equations introducing a similarity transformation. The resultant flow and heat transfer has been solved analytically. The effects of viscoelastic parameter, porous parameter, Magnetic field, suction, space and temperature dependent heat source/sink on both flow and heat transfer characteristics are presented graphically.KeywordsBoundary layer flowHeat transferKummer’s functionMHDStretching sheetViscoelastic fluidMSC 202076D1076D0976B9976M45
