摘　　要：根据数值预报方法对200 m大型散货船阻力性能进行了数值计算,并利用模型实验进行验证。采用直接求解RANS方程的方法对散货船的流场和阻力进行了数值计算,湍流模型选用RNG两方程的模式,自由面处理采用VOF法。本文对200 m散货船进行不同航速下阻力、流场和兴波的数值计算,结果显示数值预报的计算结果与模型试验结果吻合较好。本文的结果可为同类船型阻力性能数值和实验研究提供参考。In this essay, the numerical prediction method is adopted to calculate the resistance of a 200m bulk carrier, and compare with the model testing result. The method of solving RANS equation directly is used to calculate the flow field and resistance, and the VOF method is used to deal with the free surface. We calcu- late the resistance, flow field and wave distribution of a bulk carrier under different speed. The total resistance of numerical prediction method is almost the same of the result from the model test experiment. The result of this essay can provide reference to similar ship resistance calculation and model testing.
