Numerical investigation into the unsteady effects of non-axisymmetric turbine endwall contouring on secondary flows

Author: Dunn, Dwain I ; Von Backström, TW Date: Aug 2011 Turbine manufacturers are continually striving to improve turbine performance, and thus reduce emissions, which has been accelerated with the inception of the Kyoto protocol. One of the areas that have received attention is the controlling ... Read more
Observations on the selection of objective function for the optimisation of turbine endwalls using computational fluid dynamics

Author: Snedden, Glen C ; Dunn, Dwain I ; Von Backström, TW ; Ingram, G Date: Jan 2010 This study examines the results of a CFD and rotating experiment, comparing an annular and a generic end wall design for a model turbine rotor in a 1½ stage turbine at the CSIR, in an attempt to draw some conclusions regarding the proper ...

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
