Having builtin compression process, monotooth rotary compressor can reach larger discharge pressure with higher efficiency and lower discharge temperature when compared with Roots blower. So it is a good alternative for Roots blower used in various fields. In order to put this kind of compressor into market as soon as possible, theoretical and experimental study of the monotooth rotary compress...

This paper focuses on the conceptual design of a two spool compressor for the NASA Large Civil Tilt Rotor engine, which has a design-point pressure ratio goal of 30:1 and an inlet weight flow of 30.0 lbm/sec. The compressor notional design requirements of pressure ratio and low-pressure compressor (LPC) and high pressure ratio compressor (HPC) work split were based on a previous engine system s...

A single screw compressor is an important element found in many refrigeration systems. A single screw compressor with column envelope meshing pair will have long operating life than existing single screw compressors, although it is still fail to meet industrial applications. To accelerate the industrial application of the new type compressor, a design method of column envelope meshing pair is p...

Thi~ paper is baaed on the working principle of scroll compressor and after investigating the ga~ flow condition, in especial analysis the gas leaking situation between two scroll parts mutual gearing, which influence the compressor performance very much. The working process calculating model is set up, employ the soroll compressor geometric parameter, size~ error of parts manufactured as well ...

Abstract To ensure environmental and public safety, critical facilities require rigorous seismic hazard analysis to define input for their design. We consider the case of Trans Adriatic Pipeline (TAP), which is a pipeline that transports natural gas from Caspian Sea southern Italy, crossing active faults areas characterized by high seismicity levels. For this pipeline, we develop Probabilistic ...

In this paper, the experimental vibration analysis of a single cylinder air compressor based on a hypocycloid straight line mechanism (HSM) is investigated. The HSM mechanism uses planetary gears to convert rotational motion to purely linear motion. In the conventional air compressor, the slider- crank mechanism is replaced by the HSM mechanism with appropriate counterweights. The constructed s...
