Abstract

A novel idea for micro film cooling experiment is proposed and conducted. Both fabrication of a micro film-cooled device and evaluation of its performance are presented. The film cooling device is placed in a wind tunnel system for evaluation with the blowing parameter (M) ranging from 1 to 12.5 and the film jet slot heights of 25 μm, 45 μm and 50 μm, respectively. The micro film cooling performance obtained is found much higher, and the amount of cooling air used is much less, approximately two or three order magnitude lower, than that in the large-scale film cooling system. This means much saving of power consumption and more engine efficiency.
