Physics
Explosion: fireball and rising cloud
Explore the outward shock, fading fireball and buoyant mushroom-shaped cloud.
Try this
Restart to see the luminous fireball, a transient condensation front and the slower rising cloud against the mountain landscape. Change wind and cooling to compare the cloud motion.
The model and its limits
Uncalibrated exterior visualization. A low-Mach thermal solver evolves an initially hot cap and dusty stem. The fireball, condensation shell and ground dust are illustrative optical stages, not a calculated pressure wave. No yield, damage, radiation or fallout prediction.
Equations used in the module
Equations R ∝ t^(2/5) a_b ∝ 1-T_a/T T-T_a ∝ exp(-t/τ)
