摘要
采用FLUENT数值仿真和实验模拟的方法,对在温度均匀和温度分层的海水中排放热水的水下航行体的热尾流浮升过程及其与自由表面的相互作用进行了计算和模拟,获得了由水下航行体引起的自由表面的温度变化规律。在此基础上,将热尾流的试验结果与理论数值模拟结果进行了比较。此外,还得到了热尾流的浮升和自由表面的红外图像,为水下航行体探测提供了一定的理论基础。
Both FLUENT numerical simulation and experimental simulation are used to calculate and simulate the thermal wake buoyant process of an underwater vehicle discharging hot water in the sea water with uniform and vertical temperature gradient and the correlation of it with the surface. The laws of the surface temperature change caused by the underwater vehicle are obtained. Then, the test result of the thermal wake is compared with the numerical simulation result. In addition, the infrared images of thermal wake buoyant process and surface are obtained. This study provides a certain theoretical basis for the detection of underwater vehicles.
