MHD effect on convective boundary layer flow of a viscoelastic fluid embedded in porous medium with Newtonian heating

摘要

A study has been carried out to investigate the effect of magnetic field presence on the mixed convection boundary layer flow of viscoelastic fluid past a sphere with Newtonian heating embedded in a porous medium. The governing non-similar partial differential equations are transformed into dimensionless forms and then solved numerically using the Keller-Box method. Results on the effect of the viscoelastic parameter K, magnetic parameter M, and mixed convection parameter A, on the velocity and temperature of the fluid flow have been shown graphically and discussed briefly. Numerical results of skin friction as well as wall temperature are also presented in tabular form. The comparison of results obtained in the present work with the existing publication is found in excellent agreement.
