| Abstract: | It is still very difficult to estimate the axial thrust of pump-turbines or of centrifugal pumps with high accuracy. Here we developed a simple method to calculate the pressure distribution and axial thrust of pumps and turbines for very wide range of Reynolds number. The pressure distribution and the thrust of centrifugal pumps are calculated, and their dependency on Reynolds number is discussed. The effect of balancing hole is evaluated. The calculation on the water turbine makes the dependency of the axial thrust and leakage flow-rate on the Reynolds number clear. |
