采用数值模拟方法研究水下航行体标准模型Suboff的尾流场，重点研究航行体艇体、尾舵和指挥台尾流的演化及其干涉特征。研究结果揭示了艇体尾流速度很快满足Gaussian分布的自相似特征，艇体与尾舵相互作用后的尾流速度接近Gaussian分布特征，但艇体与尾舵、指挥台三者相互作用后的尾流速度则明显不满足Gaussian分布特征。因此，数值计算的研究结果明确尾舵对整个航行体尾流的影响在设计中几乎可以忽略不计，但需要考虑指挥台对整个航行体尾流的影响。
The wake field of the standard model Suboff of underwater vehicle is studied numercially, with emphasis on the evolution and interference characteristics of wake flow of hull, rudder and sail. The results reveal that the hull wake velocity quickly satisfies the self-similar characteristics of Gaussian distribution, and the wake velocity after the interaction between the hull and the rudder is close to the Gaussian distribution, but the wake velocity after the interaction between the hull and the rudder and the sail obviously does not meet the Gaussian distribution characteristics. Therefore, the research results of numerical calculation make it clear that the influence of the rudder on the wake of the whole body can be ignored in the design, but it is necessary to consider the influence of the sail on the wake of the whole body.
