| Summary: | In this paper, the problem of free convection
boundary layer flow on a solid sphere in a micropolar
fluid with Newtonian heating, in which the heat transfer
from the surface is proportional to the local surface
temperature, is considered. The transformed boundary
layer equations in the form of partial differential equations are solved numerically using an implicit finite difference scheme. Numerical solutions are obtained
for the local wall temperature, the local skin friction
coefficient, as well as the velocity, angular velocity
and temperature profiles. The features of the flow and
heat transfer characteristics for different values of the
material or micropolar parameter, the Prandtl number and the conjugate parameter are analyzed and discussed.
