Film cooling by injection into a turbulent boundary layer
- 39 Downloads
Most papers on film cooling concern injection of a homogeneous gas. Stollery et al.  examined the case of tangential injection of gas into a boundary layer, the specific heat63-01 differing little from that of the main flow,63-02.
Here we examine the effectiveness of film cooling of a thermally isolated planar wall by local supply to a turbulent boundary layer.
