感圧・感温塗料を用いた壁面の圧力・温度場計測とその応用

Pressure-Sensitive Paint (PSP) and Temperature-Sensitive Paint (TSP) have been widely used in recent years to measure pressure and temperature distribution on walls using cameras optically. PSP measures pressure using a photochemical reaction called oxygen quenching, in which the emission intensity of a dye changes with the oxygen partial pressure (~pressure). On the other hand, TSP measures temperature by utilizing the change in luminescence intensity of dyes (thermal quenching) caused by changes in temperature. The characteristics of PSP and TSP vary greatly depending on the type of dye and binder used. Therefore, selecting the appropriate dye and binder for the experimental conditions is necessary. This presentation discusses the current status of PSP and TSP and their applications.
