Abstract
In the constructional and mechanical fields, the detection of a leak on a surface is important to maintain and manage various structures, which are a bank, a dam, a tunnel and so on. When fluid is leaking out a surface of the structure, its temperature is not generally consistent with the environmental temperature. Furthermore, expansion of high-pressure gas jetted from a nozzle lessens its temperature and cools a surface around a nozzle. With the aid of the thermograph based on infrared rays, we can detect the leak where the temperature difference between the solid surface and the leaking fluid is remarkable. In this paper, the availability of the infrared radiometer is experimentally investigated to establish the effective detection method of a leak.<BR>Key Words: Thermal Visualization, Infrared radiometer, Leak, Detection Method
