摘　　要：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与试验结果进行比较,验证计算方法的可靠性;利用数值计算技术分析潜艇工程设计和试验中出现的问题,包括潜艇实艇阻力预报方法研究和雷诺数对潜艇尾部伴流场的影响研究。Numerical calculations of the 3D viscous flow condition on two models respectively of the main hull and the submarine with full appendages of SUBOFF were carried out under different Reynolds＇ number.The reliability of computing method was validated by comparing the numerical results with the test data at low Reynolds.Some problems in the submarine design and experimentation were analyzed,such as the method of model-ship correlation for the total submerged resistance of the submarine and influence of Reynolds number to the uniformity of nominal wake of the submarine.
