Early stage gas turbine blades feature complicated internal geometries in order to enhance internal heat transfer and to supply coolant for film cooling. Most film cooling experiments decouple the effect of internal coolant feed from external film co

Particle image velocimetry and particle scattering measurements are taken over a flat multi-row film cooled surface. The effect of coolant mass flow (characterized by blowing ratio, momentum flux ratio or velocity ratio) is investigated. The array in

Pressure sensitive paint (PSP) can be a powerful tool in measuring the adiabatic film cooling effectiveness. There are two distinct sources of error for this measurement technique; the ability to experimentally obtain the data and the validity of the

In gas turbine engines, film cooling holes are often fed by an internal cross-flow, with flow normal to the direction of the external flow around the airfoil. Many experimental studies have used a quiescent plenum to feed model film cooling holes and

A flat plate film cooling experimental facility has enabled a study of the flowfield features and film performance characteristics of a single row of standard axial-shaped holes (ASH). Surface IR thermography and particle image velocimetry (PIV) were

The effectiveness of film cooling from short cooling holes, scaled to engine conditions, has been shown to be dependent on the nature of the internal coolant feed. A common method of supplying coolant to film cooling holes in engine components is thr
