【 摘 要 】

References(16)Cited-By(6)Numerical analysis of the drag coefficients and the diffusion fluxes of two coaxially arranged spheres was made by use of a finite difference method with bipolar coordinate system for Rep=1-30, L/DA = 1.50-9.99 and Sc = 1.0. The present numerical data were compared with existing numerical and experimental data and showed good agreement. New correlations for the effect of the distance between two spheres on the drag coefficients and the diffusion fluxes of the two spheres were proposed. Measurements of rates of evaporation of a pendant water drop in the presence of a coaxially arranged inert solid sphere into dry air were made for Rep=30 and the data were compared with numerical data.
