🌬️ Termite Mound Airflow: Stack-Effect Ventilation Lab (2D)

A 2D cutaway of a termite mound driven by the real stack-effect equation: hot air rises through a central chimney while cool air sinks through peripheral tunnels, with live velocity, flow-rate and air-exchange readouts tied directly to the sliders.

This 2D companion trades the 3D mound's orbiting camera for a plain cutaway view that makes the physics readable: the same stack-effect equation (v = Cd·√(2gH·ΔT/T)) that drives real passive ventilation in termite mounds and chimneys now drives a live velocity, flow-rate and air-exchange readout as you drag the temperature-differential, height and tunnel-resistance sliders, so you can see exactly why a taller mound or a bigger temperature gap pulls air through faster.

⚙ Under the hood

2D stack-effect ventilation lab: hot particles rise through a central chimney and cool particles sink through peripheral loops, with a live velocity/flow-rate/exchange-time readout computed from the real buoyancy-driven stack equation.
