摘 要:现代潜艇尾翼的形式普遍采用十字形和X形两种基本形式,文中通过采用求解RANS方程的数值计算方法,结合RNG-kε、S-kω、SST-kω3种湍流模型,对带有30°、45°,60°3种X形尾翼以及十字形尾翼的潜艇阻力进行数值模拟,通过计算结果发现:对各种方案采用RNG-kε和SST-kω湍流模型进行计算时,阻力比较接近,而采用S-kω湍流模型时,阻力比前两种要大;在所有方案中,45°尾翼具有最小的阻力。There are several types of fins adopted in the modem submarine, including mainly the X-fin and the +-fin. The -+-fin and three types of X-fins with the angle of 30° ,45° and 60° are investigated. The navigating resistances of the submarine are numerically simulated by solving the RANS equation with the RNG-kε,the S-kω and the SST-kω turbulence models. Results show that the resistances with the RNG-kε and the SST-kω model are approximate,and there sistances with the S-kω modelis much greater than that with the RNG-kε and the SST-kω model. Among all turbulence models,the resistance of 45° fin is the smallest.
