摘　　要：基于CFD软件STAR-CCM+,以KCS船模及KP505桨模为研究对象,考虑气泡与水的相互作用力,利用船体建模的方法,基于欧拉多相流,通过改变孔内通气量、通气孔的位置和螺旋桨转速对船桨耦合的船模气泡减阻进行数值模拟。结果表明,孔位置一定时,高通气量下,气泡对螺旋桨影响更显著,使得螺旋桨产生振动与噪声,推力减小;通过改变通气孔位置可以得出,通气孔排布在船尾位置时气泡对螺旋桨影响最小;通过改变螺旋桨转速得出,螺旋桨转速越大气泡对螺旋桨影响越小。Based on CFD software STAR−CCM+,KCS ship model and KP505 propeller model are taken as research objects.Considering the bubble-water interaction force.Using the method of hull modeling,based on the Eulerian multiphase flow,numerical simulation of bubble drag reduction of ship model coupled with propeller is carried out by varying the amount of ventilation in the holes,the position of ventilation holes,and the rotational speed of the propeller.The results show that when the hole position is fixed,the air bubbles have a greater impact on the propeller at high air flow,causing vibration and noise;by changing the position of the vent hole,it is possible to conclude that the air bubbles have the least effect on the propeller when the vent hole is arranged at the transom position.
