Film cooling has been widely applied to the hot sections of gas turbines to protect those components from hot combustion gas. Various methods have been proposed to measure the film cooling effectiveness accurately. The transient infrared (IR) camera technique is a heat transfer method solving 1D transient heat conduction equations. On the other hand, the pressure sensitive paint (PSP) technique is a mass transfer technique, in which the concentration of oxygen is measured by the PSP and the film cooling effectiveness is calculated from the variation of concentration. In this study, the film cooling effectiveness of a fan shaped hole was experimentally measured using both heat and mass transfer methods under conditions of M = 1.0, 1.5 and 2.0, DR = 1.5. Both techniques showed a good agreement in film cooling effectiveness. In the case of the PSP technique, higher resolution and lower uncertainty were obtained compared to the transient IR technique. The maximum difference between the overall averaged film cooling effectiveness measured by the two methods was about 6%.
