摘要
The slip phenomenon will result in a deviation of the theoretical head; thus, it is usually considered as an important factor in the design process of turbomachines (compressor, pump, or turbine). A new correlation for the slip factor in radial and mixed-flow impellers is developed in this study, which is derived on the basis of the Euler equation in turbomachinery and relative eddy theory. It is a function of flow coefficient besides geometric parameters, enabling it to predict the varying trend of slip factor with flowrate accurately, and is applied to several cases for validation.
