摘要
水下航行器热尾流温度分布研究对红外探潜和鱼雷制导都有重要意义。建立了一套用于实验室热尾流测量的温度测量系统,实验研究了水下航行器排放冷却水形成的热尾流温度分布特征,通过对水下航行器在稳定温度分层水池中航行形成的热尾流的温度测量及红外摄像,发现水下航行器排放热水形成的热尾流中的温度分布特征规律明显,实验结果与数值计算结果符合较好,分析了影响热尾流温度分布的主要因素,为舰艇热尾流的数值预报研究提供了基础。
It is by the hot water disc important to research the temperature distribution of the thermal wakes which are caused harged by underwater vehicle for infrared detection of submarines and homing guidance of torpedo. The author set up the temperature measure system which is used in measuring thermal wakes in the laboratory and investigated the temperature distribution of the thermal wakes by underwater vehicle. By measuring temperature of the thermal wakes and shooting infrared images, it was found that the temperature profile characteristics of the thermal wakes was obvious and the experimental results agreed with the theory. The main factors that affect the temperature distribution of the thermal wakes were analyzed. These provide base for numerical predictive research of the thermal wakes of ships and submarines.
