Abstract
This paper uses CFD calculation tool FLUENT, based on N-S equation, and the SMPLEC algorithm and takes the standard K turbulence model numerically simulated to calculate the clearance sizes which are 0.5%, 1%, 1.5%, 2% relative to the diameter of runner size under different flow of axial-flow pump tip clearance flow and also to the axial-flow pump field band gap flow. The results show that the size of the gap affects the blade captations performance and efficiency of pump and lift. These have great influence on pump's performance. It provides the reliable theoretical basis of improving the performance of axial-flow pump.关键词
