| Abstract: | The CFD simulating of the internal flow field of multi-turbine is studied, and the problems of modeling and boundary coordination are well solved in this paper. The internal flow field of each turbine is simulated by CFD software. By comparing the simulation result with data from the experiment, the method proves to be effective. The demand for the memory and CPU of computer is greatly decreased, and the simulating is easy convergence. As each inlet boundary condition is in accord with the actual condition, the precision of CFD analyses is increased. |
