Аннотация:The results of an experimental investigation of the natural noise of flow past two versions of sound absorbing devices are presented. On the basis of the known theoretical studies and the numerical calculations of the turbulent boundary layer over a rough surface a method for describing the noise of the above-mentioned devices is developed. The tests made using large eddy simulation show good agreement between the calculated and experimental data.
