【摘要】 作者从前文 [　 ]已得到的脉动流速微分方程 [10 ]出发 ,对于粘性二元平行流动这一类流动模式 ,进行分析、研究并得到了脉动尺度、脉动流速及雷诺应力的物理方程。在封闭的条件下 ,求解了所设定流动模式下的雷诺方程 ,解析得到沿边界法线方向的流速分布公式。希望本文的工作对湍流的半经验理论的理性化进展有所帮助。更多还原

【Abstract】 Based on the equation of fluctuating velocity, this paper studies the viscous two dimension parallel flow. It offers fluctuating scale, fluctuating velocity and the equation of Reynolds stress. With theoretical analysis, it presents the longitudinal velocity distribution, all of which has resulted in a substantial improvement in present theory.更多还原
