Abstract

Convective heat and mass transfer from a rotating sphere have been study here. The study cases were divided into the rotating sphere in an axial flow and in still fluid. The heat transfer is a major part in this study because the mass transfer that we got was from analogy. The heat transfer from rotating sphere in an axial flow was solved by taking the advantage of Merk’s method, with uniform wall temperature (UWT) and uniform heat flux (UHF) heating conditions, while in still fluid we obtained a new equation for heat transfer for constant wall temperature heating condition. The result was that the heat transfer from the (UHF) case is greater than (UWT) case, while booth cases are increased with the rotation parameter (B) and Prandtl number. Now, for the still fluid case, the heat transfer increases with rotational Reynolds number and with Prandtl number. The mass transfer case had been obtained by the analogy, and because of that we got almost the same equations but with different coefficients and with the same cases that we dealt with heat transfer. A central finite deference method was used to solve fi, gi and θi's parameters for the case of heat and mass transfer from a rotating sphere.
