带前置导叶桨潜艇自航试验的数值模拟与自航因子预报

Numerical simulation on self-propulsion test of the submarine with guide vanes and calculations for self-propulsion factors

本文根据RANS代码,采用移动网格滑移交接面技术对假想的带前置导叶潜艇的自航试验、螺旋桨敞水试验进行模拟,并依据试验结果验证之,发现该方法能够较好地预报螺旋桨推力、扭矩。而后,与潜艇阻力试验相结合,预报潜艇自航因子,通过与试验结果的比较分析,验证了方法的可靠性。

Using a RANS solver, open water test and self-propulsion test of a hypothesis submarine model with guide vanes were studied numerically.The rotation of the propellers was achieved by moving grids and sliding interfaces.It shows that the calculations for the thrust and torque of the propeller agree well with the measurements.Combined with the resistance test, the self-propulsion factors are calculated. It indicates that numerical implementations are reliable by comparing computed results with experimental data.
