Abstract

In this paper, the quantitative measuring methods of Pressure Sensitive Paint (PSP), acetone Laser Induced Fluorescence (LIF) and Particle Image Velocimetry (PIV) are presented for the measuring of a complicated mixing flow field of film coolant and a mainstream. The time-averaged film cooling effectiveness was accurately measured with the PSP method, when precise calibration has been conducted. Instantaneous distributions of velocity vectors and film cooling effectiveness were measured simultaneously near the exit of circular hole by acetone LIF and PIV. The simultaneous measurement is very useful not only to clear the spatial flow field of film cooling but also to confirm the accuracy of numerical simulations of film cooling.
