This paper reports on an experimental investigation of the influences of mainstream Reynolds number and coolant density on film cooling characteristics on the leading edge of a twisted turbine blade under rotational conditions. The experiments were carried out at a test facility with a 1-stage turbine...

The film cooling is especially bad on aerodynamic performance because it interferes with the hot gas flow. However, to achieve the higher operating temperatures, FC has not found an alternative yet. Evolution of a new ceramic–matrix composite (CMC) provides opportunities to operate the turbine at...
