分支管面积对Π型并联管组的水动力计算结果影响

Effect of lateral area on manifolds flow

在并联管组水动力学基本方程的基础上,分别采用水动力推进算法和水动力标准算法,对3种不同的分支管面积的Π型集箱进行计算,比较两种算法的计算结果差异.计算结果对确定水动力标准算法的适用范围有重要意义.

Based on the mass conservation law and momentum equations of incompressible fluid in manifolds, the three examples of Ⅱ style manifolds with different pipe diameter show the difference between the marching solution method and the standard solution method. It is important to point out the suitable applicable range of standard solution method for manifolds flow.
