摘要 针对水面无人艇纵向航行问题进行静水拖曳试验.采用有限体积法结合Shear Stress Transpor(SST)湍流模型,应用动网格技术对模型周围绕流场进行了数值模拟,计算裸船体阻力及航行姿态.将数值计算与试验值对比分析,结果表明两者变化趋势相一致,该方法在阻力计算方面具有较好的精度.探讨了重心纵向相对位置对无人艇纵向性能的影响,结果表明,重心位置前移会降低第一阻力峰值,有利于避免"海豚运动",但同时会降低最高航速. In order to predict the high-speed unmanned surface vehicle(USV) longitudinal motions,model test was conducted in calm water on the ship.The flow field around the USV was numerically solved by the finite volume method in conjunction with the shear stress transpor(SST) turbulence model,which is based on dynamic mesh method.The drag force and trim angle acting on the hull were obtained.The computational and tested results appeared similar changing tendency.The result shows that the numerical method can give good accuracy.Then the effect of the different longitudinal positions of the center of gravity on propulsion performance was discussed.Moving the longitudinal center of gravity forward is beneficial to reduce the first crest amplitude of resistance and avoid porpoising,at the same time,the top speed is reducing.
