Applying CFD technique to calculating successfully hydrodynamic performance of water jet pump

Sections 1 and 2 of the full paper explain how we apply CFD (computational fluid dynamics) technique; their core is: (1) we use high quality hexahedral mesh and sliding mesh technique to simulate the hydrodynamic performance of a water jet pump; (2) the Reynolds-averaged Navier-Stokes equations and the SST (shear stress transport) turbulence model are adopted in the simulation process; (3) the simulation results, given in Figs. 8 and 9 and Table 1, and their analysis indicate preliminarily that the balance characteristic of a certain waterjet pump is satisfactory but its efficiency is low. Section 3 discusses the effects of the two CFD parameters of mesh and turbulence model on the calculation results. Finally, we believe that the successful application of CFD technique to calculating the hydrodynamic performance of the water jet pump provides a reliable and practical approach for its design and performance prediction.
