Original Abstract

Application of a casing treatment to centrifugal compressors is a possible way to influence their operating parameters such as compression, efficiency or aerodynamic noise. Based on experimental results, the implemented casing treatment showed an increase in isentropic efficiency at selected operating points and affected the compressor map width as well. These results are in an agreement with numerical simulations that predict this effect. The selected casing treatment design also affected the sound pressure level measured during the compressor operation. It is thus shown that casing treatment represent an interesting way leading to a noticeable influence on the compressor map.
