Abstract

Experimental and numerical studies were conducted for the development of the integrated impingement and pin-fin cooling structure. In the development, the spatial arrangements of impingement hole, pin-fin and film cooling (discharge) hole were the main concern of designers. The temperature measurements were performed for different test pieces with various spatial arrangements to clarify the cooling effectiveness variation with the spatial arrangements and other cooling parameters. Moreover, conjugate numerical simulation was executed to investigate the cooling effectiveness and was evaluated by the experimental measurements.
