We present first results of an implicit large eddy simulation of the MTU T161low pressure turbine at a Reynolds number of 90,000 and Mach number of 0.6,both based on isentropic exit conditions, using a high order discontinuousGalerkin method. The aim is to validate the numerical setup with respect toavailable experimental data. We discuss the steps taken to create realisticinflow boundary conditions in terms of end wall boundary layer thickness andfree stream turbulence intensity. This is achieved by tailoring the inputdistribution of Reynolds stresses and turbulent length scale to a Fourierseries based synthetic turbulence generator. Both blade loading and totalpressure losses at midspan show excellent agreement with the measurements.Following a short discussion of the secondary flow structures emerging due tothe interaction of the incoming boundary layer and the turbine blade, we showthat this simulation is also able to reproduce loss distribution behind theblade over the whole channel height.
