the main design objective of axial compressor is the efficiency increasing, pressure ratio and weight loss. these three parameters are used as an objective function and they are computed according to adopted design procedures. in this paper, a design method is presented that named quasi-three-dimensional. physical flow conditions are applied to design by some constraints to avoid irrational res...

surge and rotating stall phenomena are two dynamic instabilities that occur in both axial and centrifugal compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressing surge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. this resear...

this paper deals with aerodynamic design of fan and compressor assembly for turbofan engines having arbitrary by-pass ratios. two different softwares were developed in this respect. first, based on general performance data at design point condition, a one-dimensional approach was activated. initial flow passages of both fan and compressor, together with splitter position were developed utilizin...
