摘要：
Because the submerged waterjet propulsor is fully integrated in the ship, the force on propulsor is hard to measure in towing tank test. In this paper, towing tank test method and numerical simulation method were combined to predict the performance of submerged waterjet. The resistance, trim angle and sinkage of ship model were measured in towed resistance test. And the self-propulsion test was conducted and the rotation speed, torque and thrust of shaft, etc. were measured. The towed resistance test and selfpropulsion test were numerically simulated based on CFX software. The predicted resistance error was within 3.7%, the shaft thrust error was within 4.7% and the shaft torque error was within 4.6% at four different speeds. Proved by towing tank test, numerical simulation could get the thrust of submerged waterjet propulsor, massflow, head and other flow field information in addition, solving the difficulties in measuring thrust and flow field. © 2017, Editorial Board of Journal of Ship Mechanics.
