摘要：Hysteresis phenomena demonstrate the lag between the generation and the removal of some physical phenomena. This paper studies the hysteresis phenomena of the head -drop in a scaled model pump turbine using experiment test and CFD methods. These lag is ind uced by complicated flo w patterns, which influenced the reliability of rotating machine. Keeping the same measurement procedure is concluded for the hydraulic machine measurement
