为了对桨扇周围的跨音流场有深入的理解,用计算流体力学方法在巨型计算机上进行流场数值模拟是一条重要途径。因此引起学术界的重视。桨扇叶片具有又弯又扭的三维形状,就决定了桨扇周围流场的三维性质,给桨扇跨音流场的数值模拟带来很大的困难。为了数值求解过程中改善解的稳定性和收敛性,以及为了提高数值解的精度,就必须妥善解决三维网格系统生成问题。
In order to understand the transonic sound field around the propeller fan, computational fluid dynamics is a very important way to simulate the flow field in a giant computer. Therefore aroused the academic attention. The blade blades have a curved and twisted three-dimensional shape, which determines the three-dimensional nature of the flow field around the propeller fan, which brings great difficulties to the numerical simulation of the propeller blade transonic flow field. In order to improve the stability and convergence of the solution in numerical solution, and to improve the accuracy of numerical solution, we must properly solve the problem of generating three-dimensional grid system.
