摘要

应用雷诺平均纳维-斯托克斯（RANS）方法，使用STARCCM+商业计算流体动力学（CFD）软件，对全尺寸船舶模型KVLCC2进行了数值模拟，以计算总阻力、耐波性和纵摇力矩。获得了在不同海况（平静水域、规则波浪和不规则波浪）下15.5节的速度的结果，KVLCC2船体在平静水中计算的总阻力与实验结果非常一致，波浪中的运动（升沉和纵摇）和附加阻力的结果与先前研究的数值和实验结果进行了比较，结果非常一致。除了波浪激励外，全尺寸船舶模型还使用CFD软件中的虚拟圆盘模型进行螺旋桨激励。将KVLCC2的全螺旋桨特性简化为合力的体力-螺旋桨方法应用于虚拟圆盘模型。将结果与纯船体模型的结果进行比较。文中还给出了尾流结果与前人工作的比较。

Study of added resistance and seakeeping of KVLCC2 in waves with and without propeller

Numerical simulation of a full-scale ship model, KVLCC2, has been conducted applying the Reynolds Averaged Navier-Stokes (RANS) approach using the STARCCM+ commercial computational fluid dynamics (CFD) software to calculate total resistance, seakeeping and Pitch Moments. Results are obtained for the speed of 15.5 Knots under different sea conditions (calm water, regular waves and irregular waves), The total resistance calculated for the KVLCC2 ship hull in calm water is in a good agreement with the results from experiments and the results for motion (heave and pitch) and added resistance in waves were compared to numerical and experimental findings from previous research with good agreement. In addition to wave excitations, the full-scale ship model was subjected to propeller excitations using the virtual disk model from the CFD software. The body force propeller method, which simplified the full propeller characteristic of the KVLCC2 into a resultant body force, is applied to the virtual disk model. Results are compared with results from the hull-only model. A comparison of the wake results with previous work is also presented.
