| description | This paper deals with experimental and numerical investigation of the film cooling effectiveness on a flat plate.
Eleven injection holes on the model are in a single row. The holes have cylindrical cross section and they are 8.5
mm diameters. The injection angle is 30o. The blowing ratios vary from 0.5 to 2.0. The experiments and their
computational models have been established to investigate their effects at 57 oC injection temperature and
different blowing ratios. . The experimental and computational solutions show the blowing ratio affect on film
cooling effectiveness and a suitable blowing ratio should be selected for good film cooling performance in both
mainstream and lateral direction. In the current study, the best blowing ratio is 0.5. In additon, when the
blowing ratio is increased the film cooling effectiveness deacreases. |
