摘要
This paper presents a computational study of the forced convection heat/mass transfer from two spheres placed in a uniform viscous flow parallel to their line of centers. The temperature/concentration inside the spheres are assumed spatially uniform but not constant in time. Axisymmetric, slow, viscous flow (Stokes flow) around the spheres was considered. The appropriate energy/chemical species balance equations were solved numerically in bispherical coordinates. The finite difference method was used to discretize the mathematical model equations. Various spheres spacing, sizes and physical properties were considered at moderate Pe numbers.
