Calculation of High-pressure Gas Tank Leakage Parameters

Based on vessel dynamics of compressed gas,the calculation method for the parameters of outflow through small holes in high-pressure gas tank is presented.Taking a hydrogen storage tank outflow through a hole in the tank wall and a carbon monoxide storage tank through hole in pipe as the case,the trends of the mass flow rate and the temperature,pressure and other parameters inside the tank are computed.The results show that mass flow rate is influenced by the hole diameter and the initial pressure of vessel,while the influence of the pipe length is not so strong as expected.
