Abstract:

In this current paper, the influence of system efficiency and system parameters for simple compressed energy storage system were studied. EES software is used to simulate the pressure of system and efficiency of compressors, expanders, and pump for getting the optimal parameters of system. The results show that: for the simple system, when the expander inlet pressure is 6000kPa and compressor outlet pressure is 4000kPa, the system efficiency could get the maximum, and it is 76.2%. It is a better way for improving the efficiency of compressor and expander than the pump for system performance.

Wet compression is widely used to reduce compression work and improve efficiency in gas turbines. However, wet compression has not been industrially applied in the compressed air energy storage system (only few studies on isothermal compressed air energy storage system exist), which has an urgent demand to reduce the compression work. The high-pressure section of the compressed air energy storage system usually contains supercritical air, and the influence of supercritical wet compression is not yet clear. Thus, in this study, supercritical wet compression was numerically investigated in a cen

Abstract:

<span>One of the main reasons of the performance degradation of gas turbines is the axial compressor fouling due to air pollutants. Considering the fact that the fouling leads to high consumption of fuel, reducing of the axial compressor’s discharge air pressure and increasing of the exhaust temperature, thus designing a compressor degradation detection system will allow prevent such issues. Many gas turbine plants lose power due to dirty axial compressor blades, which can add up to 4% loss of power. In case of power plants, the power loosing could be observed by less megawatts produced

Abstract:

Rotating stall waves that travel against the direction of rotor rotation are reported for the first time and a new, low-order analytical approach to model centrifugal compressor stability is introduced. The model is capable of dealing with unsteady radially swirling flows and the dynamic effects of impeller-diffuser component interaction as it occurs in centrifugal compression systems. A simple coupling criterion is developed from first principles to explain the interaction mechanism important for system stability. The model findings together with experimental data explain the mechanism for fi

The air compressor system is a time-varying, delay and nonlinear complex system, it has a very important sense to ensure that the supply pressure is stable in the compressor control system. According to the working characteristic of air compressor system, the fuzzy control theory, as one of the modern control theories, was applied into the constant pressure control system to design a fuzzy pressure controller. The simulation results show that the controller was more convenient and effective; it has certain directive significance and reference for the other parameter’s control of air compressor

In this study, the focus is on reducing the energy that is consumed by a compressor for providing high air pressure in the reservoir. A new air suspension configuration is presented that is titled active interconnected air suspension with outsourced air pressure. In this configuration, a compressor is used to charge the tank; meanwhile, the air springs are connected. For minor excitation, first, the air flows between air springs to control roll angle and height adjustment. If the situation of body position gets worse, the compressed air tank compensates to keep the body not generating roll ang

Metal hydride (MH) actuators that use reversible reaction between heat and mechanical energy are suitable as a power source for rehabilitation or assistive devices. To avoid the risk of a hydrogen drive and obtain broader use than conventional MH actuators, we developed an MH air compressor that converts the hydrogen pressure of the MH actuator to air pressure. Although this compressor requires time to restore consumed air, it has the advantages of small size and flexible shape. Sit-to-stand motion aid for a wheelchair user that is the size of a seat cushion was developed using the MH air comp
