Cryogenic Rocket Tank 2D — Boil-off, Pressure & Sloshing

Interactive 2D cryogenic propellant tank: heat leak boils liquid hydrogen into vapor, ullage pressure builds by the ideal gas law, a relief valve vents when it crosses your set point, and lateral maneuvers slosh the liquid surface.

The 3D version of this tank is a decorative particle-swarm scene, not a working thermodynamic model, so this 2D companion builds the real physics instead: heat leak converts liquid hydrogen to vapor, the vapor fills the ullage and its pressure follows the ideal gas law, a proportional relief valve vents when pressure crosses your set point, and a maneuver's lateral g-load drives a damped-pendulum slosh of the liquid surface.

⚙ Under the hood

Heat influx and insulation efficiency set the boil-off rate; accumulated vapor raises ullage pressure by PV=nRT; a relief valve vents proportionally above its set point; lateral acceleration sloshes the liquid surface as a damped pendulum.
