温度梯度环境中潜艇尾流热特征的试验研究
Experimental study of the thermal characteristic of submarine wake in the temperature stratified flow
摘要
Abstract
In order to advance the integration level and the anti-jamming capability of the system, this paper improves the temperature measure system which is used in measuring thermal wakes in the laboratory. The thermal characteristic of thermal wake of the submarine model driven by screw propeller was studied in the flow with or without thermal stratification in the water tank, and temperature distribution of the wake and the signal decay laws were obtained under the two conditions. The formation mechanisms and main effect factors of the wake signals were analyzed, and it shows that “the cold wake” signal is more beneficial of detecting and distinguishing underwater submarine. The results obtained can provide much more practicable theoretical support for the development of technology in infrared detection of submarine and its infrared stealth.关键词
