船模自航试验数值模拟研究

Study on the Numerical Simulation of Self Propulsion Model Test

基于SHIPFLOW软件,对螺旋桨敞水试验、船舶阻力试验和自航试验进行数值模拟,并依据试验结果验证。发现数值模拟能够较好地预报螺旋桨的推力系数、扭矩系数、船模的阻力系数和自航因子及推进效率,为船舶的线型设计和螺旋桨设计提供有效的数值参考。

Based on SHIPFLOW software, the propeller open water test, the ship resistance test and the self propulsion test are numerically simulated and validated according to experimental results. It is found that the numerical simulations can well predict the propeller thrust coefficients and torque coefficients, the ship model resistance coefficients, the self propulsion factor and the propulsion efficiency, which can provide helpful guidance for the hull lines design and propeller design.
