왕복동식 수소압축기의 스너버 압력측정과 수치해석

Nowadays, study about hydrogen fuel which consist of hydrogen extraction and reforming processes, fuel cell equipment, and receptacle are flourishing allover the world. Currently, Korea hydrogen station is still underdeveloping. And also the most important part which is hydrogen compressor has not been developed. Snubber is one of the important parts in hydrogen compressing system. It is installed before and after reciprocating hydrogen compressor. Snubber has two functions. One is making down pulsation waveform. Because pressure hydrogen gas where is after passing through reciprocation compressor part has high pulsation waveform, so this waveform has to decline. And the other function is precipitating alien substances to outside. Normally, even if 99.99% hydrogen gas is still containing alien substance. Buffer is set up inside snubber and the waveform will hit buffer. This snubber study uses CFD.
