Efficient design of quiet turbomachinery stages with a unique coupling method

Most current propulsion and ventilation systems still suffer from poor efficiency, noise issues and too high emission levels. Little efficiency gain could yield significant reduction of energy waste, noise pollution, gas consumption and pollutant emission. Moreover a lot of the large rotating facilities do not meet their target performances and suffer from early degradation and fatigue issues causing some significant cost increase and losses to the companies producing them. Current design tools of such systems have been shown to be limited by their too strong modeling assumptions on the actual unsteady and turbulent nature of the flow in these systems. The present project proposes to combine the most accurate and efficient turbulent flow solver AVBP with a massively parallel code coupler OpenPALM. A coupling method based on the overset grid approach will be developed and tested to couple multi-copies of the massively-parallel unstructured compressible LES solver for turbomachinery applications.
