中文摘要 | 本文研究等濃度垂直平板與穩定層流之間的暫態質傳。此一穩定的層流,是由溫差所引起的熱浮力驅使流體沿著平板流動而建立的流場。藉由本文所發展出來的解析暫態自然對流的方法求解。對於Pr=7和1≦Le≦500的稀薄水溶液,可得到涵蓋全部時間域的精確數值解。為了便於應用,本文也提供一個準確度非常高的質傳相關式。 |
英文摘要 | This work studied transient mass transfer from a vertical flat plate with uniform concentration to a steady laminar flow. The flow is driven essentially by the thermal buoyancy arising from temperature difference between the plate and ambient fluid. By using an efficient solution method, precise numerical results have been obtained over the whole transient period including unsteady diffusion and steady convection. All the results are presented for aqueous solutions of Pr=7 and 1≦Le≦500. Very accurate correlation equation of mass transfer rate was developed for application conventience. |
