摘要
本文采用新的向量势做法计算了方截面直管内的湍流流动。讨论了流场特征并导出了不同区域的简化方程。计算结果跟实验相符,实际模拟了平均量和湍流量的主要特征。
In this paper, the turbulent flow in a straight duct of squase cross section has been computed using a new vector-potential formulation. The flowfield characteristics are discussed, and the corresponding simplified equations suitable for different regions are developed. The present results are in good agreement with available expermental data. The main features of the mean-flow and the turbulence quantities are simulated realistically.
