Abstract:For further researching on authenticity and accuracy of the numerical simulation in tubular pump, the numerical simulation in tubular pump was conducted with different parameters. The simulation calculation results were compared with the data of positive energy test of a two-way tubular model pump in Shanghai. In the process of the numerical simulation, the setting of parameters, such as the meshing of grid, the choices of computational model and the boundary conditions were compared and analyzed. The characteristics of pressure and flow pattern were observed. The closest scheme was selected, which might have referential value for tubular pump numerical simulation. The comparisons with test data and the interior pressure distribution and flow pattern show that S-A model is better than Realizable k-ε model. When the pressure of inlet is 0, the numerical simulation with S-A model is proved to be the best.
