摘要
应用Galerkin有限元和Baldwin-Lomax湍流模型,求解射流泵内不可压粘性流动N-S耦合方程,得到了射流泵内部流动参数分布。给出两个计算实例,计算结果与实测资料基本吻合,从而为射流泵内部流场的数值模拟研究提供了一种新方法。
The Galerkin finite element method and Baldwin-Lomax turbulence model are employed to solve the coupled N-S equations for incompressible axis-symmetric flow in jet pumps. The parameter distribution of flow field is then obtained. Numerical results of two examples given in this paper agree with the experimental data, and thus, a new numerical method for studying flow in jet pumps is proposed.
