Application of Spalding formula in wall friction stress measurement on riblet surface Spalding公式在脊状表面湍壁摩擦力测量中的应用
Born in Portland, OR in1984, Spalding was not well served by the public school system and soon dropped out of classes to be home-schooled. 或出生于波兰,1984年,斯伯丁没有很好地服务于公立学校系统,很快降到班列将要在家接受教育。
The viscous flow problem is calculated by modified Spalding's unified boundary layer theory. The viscous/ inviscid interaction is considered by using Lighthill's equivalent source method. 用Spalding统一边界层理论作粘性计算,以及用Lighthill的当量源方法考虑粘性/势流的耦合效应。
According to the k-ε kinetic turbulent model and the condition of constant viscosity, the flow fields under three different kinds of velocity distributions are computed. 在等粘度和k-ε紊流模型下,分别计算了三种速度分布下的流场,和国内外相关实验结果及Spalding,D。
All the governing equations are solved by the use of the SIMPLE algorithm of Patankar and Spalding. 全部控制方程用Patankar&Spalding的SIMPLE算法求解。
This paper studies the base flow caused by the incompressible fluid past through the cylinder base. The control volume method of integral developed by D. B. Spalding and S. V. Patankar is used. 研究不可压缩流体流经圆柱体底部时,形成的底部流动,其数值方法可采用由D.B.Spalding、S.V.Patankar发展起来的控制体积分方法。
