Abstract: This paper provides a unique experimental assessment of the use of a foreign gas to vary the injection-to-mainstream density ratio in film-cooling experiments. It is widely recognized that it ...

Abstract: Film cooling in the presence of mainstream pressure gradients typical of gas turbines has been studied experimentally on a flat plate. This paper describes measurements of the spanwise-averaged ...

Abstract: Transient heat transfer measurement techniques have long been used in two-dimensional stationary cascade tests designed to model turbine conditions used in Oxford. More recently, experiments studying ...
