Author:Scheepers, G; Morris, RM; Visser, JA; Roos, TH; Snedden, Glen CDate:Jan 2006This paper describes an experimental and numerical study of the heat transfer augmentation near the entrance to a gas turbine film cooling hole at different engine representative suction ratios (Vhole/V). For the experimental component the ...Read more
Author:Dunn, Dwain I; Snedden, Glen C; Von Backström, TWDate:Sep 2009In a gas turbine engine secondary flows have a detrimental effect on efficiency. The current numerical study is aimed at determining which turbulence model in a commercially available CFD code is best suited to predicting the secondary flows. ...Read more
