In this paper flow and heat transfer over a spherical particle is modeled for Reynolds numbers up to 400, and consequently different flow regimes. A three-dimensional model is applied which integrates the Navier stokes equations with a second order Adams-Bashforth Scheme. Temperature distribution inside the sphere and the consequent effect on the heat transfer coefficient is also considered in this study. The Bi number is changed over the range of 0.005-20 to study the relation between Bi and Nu numbers. It is seen that for higher Reynolds the rate of heat transfer increases. For higher Bi numbers the surface temperature changes more rapidly, therefore the temperature gradient at the surface of the particle becomes smaller and hence the local Nu number representing the rate of heat transfer at the surface of the particle will be lower.
