摘要

Numerical methods are used to investigate the transient, forced convection heat/mass transfer inside circulating spheres at low to moderate Reynolds numbers. The heat/mass balance equations were solved numerically in spherical coordinates system by a finite difference method. The values considered for the sphere interior Reynolds number are Re_(int) ≤ 1000. The computations were focused on the influence of the sphere Peclet number, Pe, and Re_(int) on heat/mass transfer rate for Pe/(1 + μ) ≤ 10~4.
