Free Convection Flow of Water at 4℃ Passing an infinite Porous Plate with Constant Suction in a Rotating System

摘要: 本文研究了旋转系统中4℃的水流经竖立的无穷大多孔板时定常自由对流的分析解.求得了速度和温度的耦合非线性方程组的近似解.讨论了爱克曼数E'的效应(普朗特尔数为P=11.4,相当于4℃的水)

Abstract: In this work an analysis of steady free convection flow of water at 4℃ passing a vertical infinite porous plate in a rotating system is considered. Approximate solutions for the coupled nonlinear equations are obtained for the velocity and the temperature. The effect of E' (Eckman number) is discussed, when P (prandtl number)=11.4, which corresponds to water at 4℃.
