An analysis of the pressure coefficient on the suction side of blades is presented as a design criterium for axial-flow pumps. A CFD model is developed and validated from experimental tests available in the literature. The model uses the finite volume method through the commercial software Ansys CFX. In the criterion application step, the X-Foil software is used to determine the lift and drag coefficients of the blade profiles. A case study is presented for the dimensioning of axial-flow pumps for a large recirculation tunnel, to be used for testing vessels, naval structures and hydrokinetic turbines. Special attention is given to pump cavitation conditions.
The criterion of the minimum pressure coefficient is then evaluated by the CFD model, showing good performance for the pump. |
