Abstract

Abstract

The flow in the internal cooling structure of the leading edge of certain real turbine blade was simulated experimentally. It is found that about more than one third of the area of each impingement hole is actually useless, and the flow distribution of the film-cooling holes is remarkably affected by the relative location between the film-cooling holes and the impingement holes.
