【 摘 要 】

References(17)Cited-By(1)In order to investigate the effect of interaction between diffusion fluxes on mass transfer from a binary solution drop, numerical analyses of mass transfer around a binary solution drop under forced convection are made by using a finite difference method for driving force ratios ΔωB/ΔωA = –10 – 10, diagonal Schmidt number ScAA = 1–3, ScBB = 0.5–3, nondiagonal Schmidt number ScAB = 1–10, ScBA = 1–10 and Reynolds number ReP =1–200.The effect of driving force ratios, Reynolds numbers, and multicomponent Schmidt numbers on the concentration profiles and the diffusion fluxes of a binary solution drop are discussed. A new correlation is proposed for the effect of interaction between diffusion fluxes on mass transfer around a binary solution drop under forced convection.
