In order to study internal flow pattern, the 3D flow in inducer with helical static blades is numerically computed by using the computational fluid dynamics (CFD). The suction and cavitation performance of the inducer are analyzed. The results show that the head increases with helical static blades, while the efficiency decreases resulted from the strong backflow in helical static blade channels. As the inlet pressure decreases, the cavitation develops along the radial direction, which is influenced by the centrifugal force. The choked helical static blade channels delay the appearance time of blocked inducer, so the cavitation performance of the inducer with helical static blades is improved.
