Experimental and numerical study of near bleed hole heat transfer enhancement in internal turbine blade cooling channels

Author: Scheepers, G ; Morris, RM ; Visser, JA ; Roos, TH ; Snedden, Glen C Date: Jan 2006 This 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
Turbulence model comparisons for a low pressure 1.5 stage test turbine

Author: Dunn, Dwain I ; Snedden, Glen C ; Von Backström, TW Date: Sep 2009 In 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
