Abstract

The effects of pressure stress work and thermal radiation on free convection flow around a sphere embedded in a porous medium with Newtonian heating is considered. The basic equations of boundary layer are transformed into a non- dimensional form and reduced to nonlinear system of partial differential equations and solved numerically using an implicit finite difference technique with Newton s linearization method. Comparisons with previously published work are performed and excellent agreement is obtained. Numerical results have been shown graphically and tabular forms for some selected values of parameters set consisting of radiation parameter, pressure stress work parameter, Newtonian heating coefficient and Prandtl number.
