Abstract
This article is concerned with the class of solutions of gas boundary layer containing
uniform, spherical solid particles over the surface of rotating axi-symmetric roundnosed
body. By using the method of transformed coordinates, the boundary-layer equations
for two-phase flow are mapped into a regular and stationary computational domain and then
solved numerically by using implicit finite difference method. In this study, a rotating hemisphere
is used as a particular example to elucidate the heat transfer mechanism near the
surfaces of round nosed bodies. We will also investigate whether the presence of dust particles
in carrier fluid disturb the flow characteristics associated with rotating hemisphere or
not. A comprehensive parametric analysis is presented to show the influence of the particle
loading, the buoyancy ratio parameter and the surface of rotating hemisphere on the
numerical findings. In the absence of dust particles, the results are graphically compared
with existing data in the open literature and an excellent agreement has been found. It is
noted that, the concentration of dust particles parameter, D_p, strongly influence the heat
transport rate near the leading edge.
