摘要：
For orifice plate discharge tunnel, flow pulsation is closely related with cavitation and discharge tunnel's safety. In the present paper, the characteristics of orifice plate flow pulsation and its effects on cavitation are researched. The research results show that orifice plate flow turbulence belongs to low frequency and large pulsation. Orifice plate flow pulsation pressure is related with orifice plate's contraction ratio and it increases orifice plate's cavitation damage risk. When taking into account orifice plate cavitation, flow pulsation pressure must be paid attention to.
