영문 초록

A complex passage analysis on suction valve has been performed with a high pressure reciprocating hydrogen compressor. General information about an internal gas flow is presented by numerical simulation approach. Flow characteristic analysis, including pressure and turbulence kinetic energy distribution of hydrogen gas coming to the cylinder of a reciprocating compressor are presented in this paper. Suction passage model is designed based on real model of hydrogen compressor. Pressure boundary conditions are applied considering the real condition of operating system. The result shows static pressure and turbulent kinetic energy are not distributed uniformly along the passage of the Hydrogen system. Path line or particles tracks help to demonstrate flow characteristics inside the passage. Based on this result, the design improvement, such as reducing the varying flow parameters and flow reorientation should be done. Consequently, it will be achieved much better hydrogen compressing system.
