In this work we present a method based on Proper Orthogonal Decomposition (POD) to predict the flow and the losses in a radial turbine. The modelling approach allows continuing the time marching of detailed Large Eddy Simulations (LES) in the parameter space of the problem (i.e. for variations in flow parameters and/or boundary conditions). The purpose is to obtain a reduced model for the turbocharger components and the manifolds of internal combustion engines. The suitability of using POD as a base for the reduced model is demonstrated on a radial turbine of a passenger car engine.
