N2 - To understand the influence of flow parameters on the phase interaction in the multiphase rotodynamic pump, simulations with ANSYS CFX were performed under different IGVFs (3%, 9%, 15%) as well as different flow rates (0.75Qd, Qd,1.25Qd) and different bubble diameters at impeller inlet (0.1 mm, 0.4 mm, 0.7 mm, 1.0 mm). The numerical results show that the drag is the most important and the magnitude of turbulent dispersion force can be neglected. The interphase forces increase gradually with the increase of IGVFs. Furthermore, the increase of interphase forces in impeller is greater than that in guide vane. Under condition of Q=0.75Qd, the drag, added mass force and lift at impeller inlet, as well as the drag at the middle of impeller, increase significantly. Meanwhile, the change trend of interphase forces is obvious than that in guide vane if the bubble diameter increases at impeller inlet.
