Radiation effects on MHD flow of second grade fluid through porous medium past an exponentially stretching sheet with chemical reaction
Keywords:MHD stretching sheet, chemical reaction, second grade, Eckert number, thermal radiation
This article looked at the effects of electromagnetic force, chemical radiation, and thermal radiation on second-grade fluid passing through an exponentially stretched sheet with a heat sink and a porous medium. Using similarity transformations, the governing system of nonlinear partial differential equations has been converted into a system of ordinary differential equations. The Successive Linearization Method is then used to solve the system numerically. Graphs are used to display the numerical findings for the profiles of velocity, temperature, and concentration. The effects of various parameters are looked at and evaluated. The numerical values of the local Sherwood number, local Nusselt number, porosity, retardation number, and skin friction coefficient are presented and examined. The findings show that a wide range of variables significantly affect the fluid flow patterns. The reaction rate parameter had a significant impact on the concentration profiles, and as the reaction rate parameter grew, the boundary layer's concentration thickness reduced. The analysis's findings and the findings of previous studies were compared, and it was discovered that they were in excellent agreement.
