In recent years, several research activities have been conducted to develop knowledge in analysis, design and optimization of compressor anti-surge control system. Since the anti-surge control testing on a full-scale compressor is limited to possible consequences of failure, and also the experimental facility can be expensive to set up control strategies and logic, design process often involves...

design models of multi- stage, axial flow compressor are developed for gas turbine engines. axial flow compressor is one of the most important parts of gas turbine units. therefore, its design and performance prediction are very important. one-dimensional modeling is a simple, fast and accurate method for performance prediction of any type of compressors with different geometries. in this appro...

In a compressor the existence of the clearance volume is inevitable, even rolling piston compressor is a kind of compact structure compressor, overflow is a method to decrease the effect of clearance volume. In this paper, the overflow design on a rolling piston rotary compressor is discussed, which uses the high-pressure gas in the clearance volume, and discuss its effect on the performance of...

surge is one of the two destructive factors in compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressingsurge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. according to moore-greitzer compressor model, this paper designs an act...

The weakening of the fatigue strength of turbine blades due to local impa caused by foreign objects (Foreign Object Damage FOD) represents i3 safety risk in modern aviation. It is possible to employ deep rolling to courat component weakening in a particularly effective way. In order to derive a possible process parameter-set in advance, fundamental knowledge regarding the elastic and plastic de...

The performance prediction of axial flow compressors at different speeds and under various pressure ratio conditions are still being developed because of costly empirical experiments. One-dimensional modeling is a simple, fast and accurate method for performance prediction in any type of compressor with different geometries. In this approach, inlet flow conditions and compressor geometry are kn...
