Numerical simulation of mooring performance of waterjet propulsion system
A calculation method based on volume of fluid(VOF)was adopted based on mooring tests to numerically simulate the flow field characteristics of waterjet propulsion under mooring conditions in order to analyze the internal flow characteristics of waterjet propulsion under mooring conditions.The comparison with the mooring test data showed that the total thrust and torque obtained based on this method agreed well with the test data.The method can effectively simulate the free jet flow field of the waterjet propulsion.The numerical simulation results of waterjet propulsion show that the growth rate of the Euler's head inside the impeller tends to be constant as the impeller speed increases,and the efficiency of the impeller increases.The areas with high entropy increase inside the impeller are mainly distributed near the impeller inlet,wall surface and blade tip,where the flow loss is large,which is closely related to the significant flow separation at waterjet duct under mooring conditions.
