Abstract

In recent years, as environmental regulations related to energy have been strengthened, the demand for higher efficiency has increased worldwide. Therefore, for optimizing or improving pump systems, it is important to find various design parameters of impellers to predict performance according to the change in parameters and to improve performance by optimizing the parameters. CFD has been used in this study. The optimum values of design parameters, such as diameter, leading edge angle, inlet angle, outlet angle, and wrap angle of an impeller, were obtained for the centrifugal pump. Various cases were analyzed using response surface methodology, and optimized design parameters were obtained as a result. The final values of the parameters show that the predicted performance curve is in good agreement with the experimental curve.
