버퍼의 넓이가 다른 스너버의 수치해석 비교

Abstract

Pulsation is an inherent phenomenon in reciprocating compressors. It interacts with ping to causevibrations and performance problems. Indiscriminately connecting to a compressor can be dangerous and cost money in the form of broken equipment and ping, poor performance, inaccurate metering, unwanted vibration, and sometimes noise. Piping connected to a compressor can materialy affect the performance and response. To minimize these detrimental effects, reciprocating compressor system should be equipped by pulsation suppression system. The system usually comprises bottle volume, caled snubber. Snubber is one of the most important parts in hydrogen compressing system. It has installed reciprocating hydrogen compressor. One of these components is snubber which has function to reduce pulsation waveform and to remove the impurities in the hydrogen gas. A snubber has an inclined plate as a buffer, which is installed inside snubber. When the pressure los and the pulsation of pressure within a snubber is minimized, the snubber could get more aplicability. Therefore, a to find an optimum geometric size on a several snubbers which have different buffer width, has been conducted using a numerical analysis.
