自励振動式ヒートパイプ内部温度場計測

抄録

The mechanism of Pulsating Heat Pipe (PHP) is still unclear because of its complex thermal fluid property. There are few researches that measured the temperature distribution inside the PHP. This study firstly challenged the visualization of temperature distribution inside a PHP. Temperature sensitive paint was painted on the silicone sheet. The TSP was excited by UV LED light and the luminescence intensity was captured by CMOS camera. The fluid and wall temperature inside the PHP was measured instantaneously. We firstly captured a thermal flow induced by the evaporation and oscillation.
