    Abstract
  • In order to study the effect of tab on film cooling,three equilateral triangular test tabs with different blockage ratio were designed,and their effects on heat transfer characteristics of film cooling were experimentally studied.The test results show that the efficiency of film cooling with tab is better than that without tab.The efficiency of film cooling will be increased with the increase in blow ratio,and it has a highest value in the direction of flow.When the blow ratio,the cooling efficiency will be increased with the increase in blow ratio;but when the blow ratio,the cooling efficiency will be decreased with the increase in blow ratio.
