For the application to film cooling of turbine blades, experimental investigations are made on the blowing characteristics of a single hole on a circular cylinder in cross flow, and on film cooling with injection from rows of holes located near the leading edge of a flat plate model with a blunt nose, and on the change in the flow pattern of the injected flow around the model by visualizing technique. It is concluded that the flow rate coefficient of an ejection hole varies under the influence of the main flow, and that the film cooling effectiveness downstream of rows of blowing holes is sometimes lowered by excessive injection, and that the inclination of ejection holes in the spanwise direction shows very high cooling effectiveness.
