| Abstract: | It is important to research the temperature distribution of the thermal wakes which are caused by the hot water discharged 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. |
| Keywords: | thermal wake temperature measuring temperature difference infrared image |
