...Fernando Gisbert; David Cadrecha; Patxi Apoita This paper analyzes the effect of the inlet end-wall boundary layer on the secondary flow of a low pressure turbine airfoil cascade at Reynolds number 2 × 10 5 using RANS and implicit large-eddy simulations (LES). The results are compared against...

...Thomas Hösgen; Matthias Meinke; Wolfgang Schröder The flow in a 1.5-stage axial turbine is investigated by large-eddy simulations. The focus is on the ingress in the downstream wheel space. Two setups are considered. In the first, the full 360 deg annulus is included on a computational mesh...

...Maxime Fiore; Nicolas Gourdain This article presents the large-eddy simulation (LES) of a low-pressure turbine (LPT) nozzle guide vane (NGV) for different Reynolds (Re) and Mach (Ma) numbers with or without inlet turbulence prescribed. The analysis is based on a slice of an LPT blading...

... alternating yaw angles ± β . Results of several large-eddy simulations are presented with varying blowing conditions and yaw angles. The effects on the achieved cooling and the generated losses are studied. The film-cooling Reynolds number (based on the fully turbulent hot boundary layer along a flat...

.... Assoc. Editor: Je-Chin Han. 24 06 2008 22 04 2009 18 10 2012 Numerical simulation results using large-eddy simulation of a flow configuration relevant to the film cooling of turbine blades are presented. The flow configuration and the simulation parameters are chosen according...
