摘　　要：分析潜艇阻力预报的方法和特点,采用数值计算方法对SUBOFF潜艇的主艇体模型和全附体模型在不同雷诺数条件下进行三维粘性流场数值模拟,将低雷诺数条件下的计算结果同试验结果进行比较,验证了计算方法的可靠性;通过对计算结果的分析,获得潜艇粘压阻力系数随雷诺数变化的规律,对潜艇实艇阻力预报提出一些建议。The method and characteristic of model-ship correlation on total submerged resistance of submarine were analyzed. Numerical calculations of the 3D viscous flow condition on two models that include the main hull and the submarine with Full Appendages of SUBOFF were made in different Reynolds. The reliability of computing method was validated by comparing the computing results with the test data at low Reynolds. The relation between submarine＇s coefficients of viscous pressure resistance with Reynolds was found out by analyzing the result of computing, and some suggestions on model-ship correlation on total submerged resistance of submarine were put forward.
