摘要
提出了求解弯管、孔板、三通等管件中的瞬变流动的二维理论模型和数值计算方法。对瞬变流动的二维控制方程进行坐标变换，得到计算坐标平面上的控制方程，并给出了计算平面和物理平面网格点一一对应关系方程和数值求解方法。建立了计算平面控制方程的边界条件，给出了差分求解方法，并提供了计算实例。
In this paper, the two-dimensional theoretic model and numerical computation method for solving transient flow in some pipe junctions, such as elbow, T-junction, orifice, etc. , are presented. The two-dimensional control equations are converted into another form with coordinate transformation. The equations＇ boundary conditions in new coordinate system are given, and Mac Cormakk difference scheme is used to solve the control equations.
