| Abstract: | 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. |
