In this project the possible use of underexpanded jets for turbine blade cooling shall be investigated experimentally. Underexpanded jets have a strong tendency to bend towards curved surfaces, so that these films have a high potential even for turbine blade leading edge film cooling. The experiments are performed in the turbomachinery blade cascade test rig of the institute to see whether this effect results in an improvement in turbine blade film cooling efficiency.
