Effect of pum** chamber on performance of non-overload centrifugal pump
In order to specify the characteristics of un-overloaded centrifugal pumps, the IH100-65-200 pump was chosen as the model pump. Different calculation models for centrifugal pumps were established under differe...

Unsteady flow structures in centrifugal pump under two types of stall conditions
The stall is an unsteady flow phenomenon that always causes instabilities and low efficiency for pumps. This paper focuses on the unsteady flow structures and evolutions under two types of stall conditions in ...
