Numerical analysis of open water performance of propellers of axial-flow pumps based on panel method

The modified panel method was employed to evaluate the open water performance of propellers of axial-flow pumps,including the external characteristics,the pressure distribution and induced velocities. The calculated results were compared with those by use of the computational fluid dynamics software CFX under the same condition. The analytic results indicate that the proposed panel method can get satisfactory results of dynamic performance of propellers of open axial-flow pumps. The calculated results agree with those predicted by the software CFX.
