| Abstract: | Reverse operation of centrifugal pumps can play the role of energy recovery turbine to recover fluid energy and its key is how to select a proper working pump for it.Based on dimensional analysis,a mathematical model for predicting the performance of the pumps working as turbines was put forward.On the basis of this model,three chemical centrifugal pumps with specific speed of ns=32.2,46.2,63.3 were experimentally simulated in reverse modes.Using the obtained numerical result,a computation formula of perfor... |
