Abstract
Accurate noise simulation of fans are very important issues as various kinds of fans are widely used in aircraft, cars and air conditioning systems. It is known that the noise radiated by of low speed fans is of tonal and broadband character, and both contributions are equally important in most configurations. This paper seeks to perform numerical broadband sound simulations of a ducted industrial fan, whose inlet geometry is simplified to an axisymmetric cylindrical duct with axial uniformity. The simulation is carried out based on DLR CAA solver PIANO, which is based on structured, curvilinear multi-block grids.
