Abstract：Focusing on a 36m3 horizontal pVTt standard container, the intake process and homogeneous process of the gas in the container were numerically simulated in constant wall temperature and constant velocity as the inlet boundary condition. A new algorithm for calculating the average temperature in the standard pVTt container was proposed, whose name was mass temperature average. The simulation results showed that in the natural convection process after gas intake, the average mass temperature of the gas in the container slowly decreased with time in parabolic shape and tended to wall temperature, while the average pressure drops sharply and quickly reached uniformity. Through numerical simulation and experimental verification, it was found that the gas mass in the container was linear with lnT.
