Abstract

A series of Large Eddy Simulations (LES) of flow in a modern, highly loaded low-pressure turbine cascade, with and without oncoming wakes, has been performed. The computations were carried out using 64 processors on the Hitachi-SR8000 F1. The blade shape is that of newly designed turbine rotors which allow controlling the blade weight. Five different operating conditions were investigated by changing strength and frequency of the incoming wakes. The large number of simulations was made possible by a previous careful tuning of the code.
