The objective of the thesis is to study the effect of the counter-rotatingsystem on the performance of centrifugal compressors and the ability to improve a surgeregion when the flow is very low flow rate. The single rotor of the conventional centrifugalcompressor is replaced by two counter-rotating rotors, which have the same size. Theremaining components of the compressor are preserved. Experimental results show that theuse of a counter-rotating system not only improves the performance of the compressor atrotational speeds lower than the design speed but also decreases the instability region. Thecompressor operating in counter-rotating mode gives a better pressure ratio as well as abetter efficiency than the conventional compressor. A co-r...
