In this respect, computational fluid dynamics may represent a tool to overcome these difficulties and analyze the flow details of arbitrary ejector geometries. In this chapter, we will try to overview some of the main features that should be considered in order to set up a reliable CFD scheme for ejector flow : Giuseppe Grazzini, Adriano Milazzo, Federico Mazzelli.
