Abstract
The authors deal with the formulation and solution of a boundary value problem describing the influence of natural convection on forced convection during diffusion to a sphere in a laminar flow regime, the orientation of the natural convection being opposite to that of the forced one. The results of numerical solution are discussed and compared with the case where the orientation of both types of convection is the same. There is a good qualitative agreement with illustrative physical concepts referring both to hydrodynamics and concentrations.
