内容記述 | Pumping head of semi-open impeller is known to drop rapidly with an increase of tip clearance. This head drop has long been treated as the result of increase of hydraulic loss in an impeller channel due to leakage through tip clearance. The present paper reveals that the head drop is mainly caused by a rapid drop of theoretical head due to recirculation flow existing at the impeller outlet. The PIV measurement and CFD calculation of a very low specific speed impeller flow show that the recirculation flow brings low angular momentum into the impeller channel through tip clearance and decreases both the pumping head and the shaft power. | |||||
