Abstract
In order to investigate the phenomena of “Temperature Swing Heat Insulation Coat” , we developed a high response temperature measurement technique by using a phosphor. Firstly, we confirmed the sensitivity and the response of this technique are sufficient for the investigation. And then, this technique has been applied to diesel spray flame impingement section where large heat loss reduction can be expected. As a result, we could clearly measure the difference of swing phenomenon between heat insulation coat and basic metal surface for the first time.
