Abstract

This work deals with film cooling of a surface with injection through slots. From the vast number of literatures surveyed, the cooling effectiveness for an ideal geometry—a flat plate with no pressure gradient having tangential blowing from a slot with no lip thickness—could be found by using a suitable blowing parameter for three different regions. The influence of blowing angle and lip geometry has been investigated and defined, each separately.
