October 2026 - Boltzmann Flyer (wind tunnel game)
Fly airfoils through a wind tunnel where the air is a live Lattice-Boltzmann flow simulation, computed in your browser. Lift and drag are not formulas: they come straight out of the simulated flow, so pitch up too far and the flow separates, vortices shed and the lift starts to shake, just like a real stall. Every level is a new shape, from NACA profiles to a spinning Magnus cylinder and a flying brick. Play it: https://dynasus.com/boltzmann/
How realistic is it? The game's flow solver tested against wind tunnel experiments and published simulations at the same Reynolds number (report in Swedish): https://dynasus.com/boltzmann/validering.html
