Abstract:Axial flow circulating pumps (AFCP) are one of large marine steam turbine unit for large-sized ships. One peculiar operation condition for AFCP is when a ship cruises beyond a certain speed, the energy of pump inflow is able to completely overcome the frictional resisting moment of the pump itself, thereby driving the impeller to rotate. Such a condition is also known as the unpowered driven condition (UDC). At this time, the fluid is in the artesian flow state. <p>In this paper, pressure fluctuation and… Show more
