Open publisher page 0 citations

Abstract

This paper studies the internal flow status of jet pump using the weakly compressible theory,such as large eddy simulation method,finite volume method and body fitted coordinate technique.Through the numerical simulation,the internal flow fields of jet pump are calculated under the condition of different throat lengths and the optimal sizes of throat are obtained.Compared with the experimental data,the computational results are proved to be rational and reliable.
