Prediction of Pulsating Turbine Operation Using 1-D - 3-D Co-Simulation

This paper describes a possible approach of designing an unconventional turbocharger using co-simulation method. Our goal is to design turbochargers running optimally during pulsating and transient modes. It means to develop a tool capable of co-simulation between 3-D and 1-D CFD. This tool must be fast and precise enough and provide a reliable result. Influence of a coarse mesh versus fine mesh was examined. Different time step size was applied to determine calculation sensitivity. Different types of turbines were tested.
