对圆形截面管道中的湍流粘性不可压缩流进行了雷诺数范围从 2000 到 10 000 的详细数值研究。研究了极限状态下运动的演化和平均特性的分布。详细的比较表明计算结果与已知的实验数据之间具有良好的总体一致性。讨论了差异的可能原因。
Turbulent viscous incompressible flows in pipes of circular cross section are subjected to a detailed numerical investigation on the Reynolds number interval from 2000 to 10 000. The evolution of the motion and the distribution of the average characteristics in the limiting regimes are studied. A detailed comparison shows good general agreement between the results of the calculations and the known experimental data. Possible causes of the differences are discussed.
