Abstract

The paper presents a mathematical model and research methodology, i.e., determination of working characteristics of mechanically driven centrifugal compressors used in the process of supercharging special purpose high power diesel engines (780 HP) with intake air. A special research laboratory installation was created for research with the aim to check and adapt compressors to the needs of the operating cycle of new or generally overhauled special purpose diesel engines. The paper provides a complete testing methodology and presents a mathematical model that can be very interesting and useful to other researchers in similar applications of this compressor type. After determining the compressor operating characteristics on the research installation, the compressor is then installed on the engine and the declared engine output parameters are monitored on a special research installation for engines.
