Abstract

The seek for an efficient aerodynamic and aeroacoustic design of axial-flow fans is an important field of investigation for both academic and applied research. Improvements can only be made with a better understanding of the physical mechanisms arising in these machines that combine strong interactions between rotating and non-rotating parts of highly complex geometries. One way is to couple well-suited experimental investigations and innovative computational methods, that overtake the weaknesses of methods based for instance on aeroacoustic analogy. In this paper we study an axial fan using a new numerical method based on LES/LPCE Brinkman Penalization Method. This method is developed in the Department of Mechanical Engineering at Korea University. The experimental tests and validations are performed in the Laboratory of Fluid Dynamics at Arts & Métiers ParisTech in Paris. Detailed analysis of numerical and experimental results are in progress within the two partner teams. In this paper we present preliminary encouraging results.
