Hydrogen compressing system is the most important part of hydrogen economy. There develop inherently pressure pulsation in reciprocating hydrogen compressing system. Snubber unit has been employed then to decrease it. An experiment has been conducted to investigate the performance of snubber used in reciprocating compression system. CFD analysis is applied to get the pressure values at different sections of this system. Regression models are also developed for amplitude at input and output of the snubber. A comparative study of pressure and amplitude by experiment, regrssion model and CFD model are performed for 35, 40 and 45hz motor frequency. These models results are varied by 0.844%, 0.117% and 0.475% from the experiment for those motor frequencies. The pressure losses in the snubber are also found almost similar values by the model i.e. 0.024%, 0.030% and 0.016% deviations.
