Abstract


In this paper we present recent research regarding the influence of geometric variations on the flow and the generated noise. Our basic configuration has been a wall mounted square cylinder, which exhibits a tonal noise. This setup was modified by attaching different shaped bodies to the square cylinder. For each configuration we have performed detailed experimental and simulation based investigations. As a result, we can state, that the level of the total turbulent energy in the flow field behind the cylinder is not the dominant criteria for the estimation of the radiated acoustic pressure level. However, an important factor plays the anisotropy of the turbulence. © 2007 by Stefan Becker.
