压力缝隙螺旋流边壁切应力及压力分布

Wall shear stress and pressure distribution of spiral flow in pressure crevice

本文通过对压力缝隙螺旋流中实测流动角变化规律的分析，探讨流速，边壁切应力的计算，以及边壁切应力的分布及其影响因素，计算压力分布，并与实验值进行了验证．

Abstract:This paper is to compute the distribution of velocity,wall shear stress and pressure of spiral flow in pressure crevice based on the analysis of the variation law of experimental flow angle. The computational result is verified by the experimental data.Keywodrs:spiral flow,pressure crevice,flow angle,wall shear stress, distribution of pressure.
