Room airflow studio
Arrange furniture and explore three-dimensional airflow and air renewal.
What happens
Arrange furniture and explore three-dimensional airflow and air renewal. Left drag on a footprint: move furniture. R: rotate. Right drag: orbit. Moving furniture restarts the air. Overlaps are rejected. Educational 3D model. Coarse vertical cells; impermeable voxel furniture; numerical diffusion. The roof and front walls are cut away only in the view. Not an HVAC design calculation.

The model and its limits
Educational incompressible 3D flow with limited corrected transport. Inlet variation changes the profile while preserving total flow. Small turbulent scales and thermal transport are not resolved. Lines show the instantaneous field, not particle histories.
Equations used in the module
Equations ∇·u = 0; ∂u/∂t + (u·∇)u = −∇p/ρ + f ∂c/∂t + u·∇c = 0; ACH = 3600 Q / V 8 × 6 × 3 m; Δx ≠ Δy ≠ Δz; c = 1 → 0
