For further study on the effects of exit guide vane on performance of axial-flow pump,numerical and experimental methods are both adopted.Based on the Reynolds averaged Navier-Stokes equation,the turbulence model and SIMPLEC algorithm in software Gambit are chosen to simulate model pump of Beitan station in South-to-North water diversion projrct.Comparing numerical simulation results with experimental results and observing internal flow characteristics of axial-flow pump,it can be drawn a conclusion that the water in outlet passage flow appears turbulence and its streamline has obvious rotation without guide vane;while the guide vane can improve flow pattern and increase efficiency of axial-flow pump.
