自动力潜艇热尾流水面热特性的实验研究
|
摘要
本文研究了实验水槽中自动力潜艇热尾流水面热特性,消除了除潜艇自身特征外其他拖动组件对热尾流扩散的影响,更加准确地再现了热尾流的扩散过程。通过热尾流温度分布预测了潜艇热尾流由热流区和冷热流混合区2个区组成,解释了2个区形成的过程,而热流区几乎全部由热流团组成,而且温度相对更高。红外热像仪拍摄的潜艇热尾流水面温度场分布图再次验证了热尾流水面热特性预测的正确性。本文对红外遥感探潜具有一定的参考价值。
This paper discusses thermal characteristics of surface thermal wake of remote control submarine in the water channel. In this research, influences caused by other structure features except self features of submarine are eliminated and diffusion process of thermal wake is reappeared accurately. According temperature distribution of thermal wake, this paper estimates that thermal wake of submarine consists of hot area and hot-cool mixed area, then forming process of abovementioned two areas is explained. Hot area is made of hotter water flow, of which temperature is higher than other areas.Correctness of thermal characteristics of thermal wake is verified by surface temperature field picture. This paper has reference value for infrared detection.
