Abstract

This paper presents an experimental investigation on the injection characteristics of a single hole at the leading edge of a flat plate immersed in mainstream air.
The influence of the hole diameter, hole inclination angle , and pressure difference coefficients on the flow rate coefficient of an injection hole is investigated.
For designing film cooled blades, it is necessary to predict the characterestics of the coolant flow rate from each injection hole. It is found that the maximum flow rate coefficient occurs at a hole inclination angle of 35o for different hole diameter and different pressure coefficient. Flow rate coefficient increase with increasing pressure coefficient.
