Studies on the distribution of wall temperature of impingement and film cooling of combustion chambers. (1) experiment

This study was conducted by simulating the heating of the real combustion chamber wall. The distribution of 1-D axial wall temperature of coolant air with different flow rate was investigated in terms of three impingement and film cooling test components with different geometric parameters and was compared with the experimental results of pure film and channel film cooling. It can be concluded that the cooling result of the impingement and film cooling is superior to that of the pure film land channel film.
