Numerical modeling of the car's metal-cylinder thermal state when filling methane
A mathematical model of the thermal state of typical automobile cylinders, which is used in numerical simulations of temperature and pressure at the metal-methane filling the balloon is created. This process is accompanied by the uneven heating of the main structural elements of power that influences their mechanical interaction and can shorten the service life of the cylinder. Metal-bearing metal cylinder liner, reinforced composite materials on the outer surface of the cylindrical shell is considered. A revised version of the equation of methane state, used in the simulation, and most closely is correlated with the experimental data. The results of numerical simulations at different ambient temperatures and the rate of filling affecting the finite mass of methane in the cylinder at a fixed final pressure are presented. The possibility of increasing the final weight of methane by cooling the cylinder in the pause between steps is required.
