This paper presents the results of numerical simulations examining thermodynamic processes during hydraulic hydrogen compression, using COMSOL Multiphysics® 6.0. These focus on application compression systems, particularly in refueling stations. The computational models employ CFD and heat transfer modules, along with deforming mesh technology, to simulate gas dynamics. superposition method was applied simplify analysis liquid piston interactions within a stainless-steel chamber, accounting for exchange between hydrogen, oil (working fluid), cylinder walls. study investigates effects varying stroke durations initial pressures, providing detailed insights into temperature distributions energy consumption under different conditions. reveal that upper region chamber experiences significant heating, highlighting need efficient cooling systems. Additionally, show longer strokes reduce power requirement pump, offering potential optimizing system design reducing equipment costs. offers crucial data enhancing efficiency paving way improved thermal management high-pressure applications.
