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...

Centrifugal compressors are widely used in many industrial fields such as automotive, aviation, aerospace. However, these turbomachines suffer instability phenomenon when the flow rate is too high or low, called rotating stall and surge. These phenomena cause operation failure, pressure fluctuations vibrations of thorough system. Numerous mechanical solutions have been presented to minimize ins...

This paper proposes a control system for integrated pressure and surge control of centrifugal compressors for enhanced oil recovery application. The proposed control system is based on linear model predictive control. A fully validated non-linear dynamic model was developed in order to simulate the operation of the compressor at full and partial load. The model of the compression system include...

The present paper is a numerical and experimental comparative study of hermetic and semi-hermetic reciprocating compressors working with carbon dioxide as fluid refrigerant against the conventional R134a hermetic compressors. When cooling conditions for one-stage compressor type (i.e., evaporation temperatures between 7.2oC and –10oC) have been considered, the numerical and experimental results...

per is concerned with the control of a three-stage compressor with upstream roots blower. Based on the detailed mathematical model derived in the first part of this contribution, a simplified model for controller design is developed in this part by exploiting the periodicity of the system variables of the piston compressor. Afterwards, a nonlinear multiva-riable control strategy is proposed for...
