Abstract

The demand of development and application of computational aeroacoustic (CAA) prediction tools for turbulence related noise is increasing to overcome the future requirements of low noise design. Fast and accurate prediction methods are necessary to be integrated into early design processes. Several numerical and experimental studies show that the complex flow physics even of simple geometries is still not fully understood. A great interest is the identification and quantification of noise sources. Hence, immense effort has to be spent for a detailed investigation of the capability of experimental and numerical methods with respect to industrial applications. In this context the uncertainty analysis of aeroacoustic computation is a key issue for the evaluation of low-noise design.
