Duct Network Airflow Simulator

Animated Duct Tree · Velocity Bands · Pressure Drop

When to use: Visualize airflow velocity and pressure drop through a branched duct network. Color-coded velocity bands (green/amber/yellow/red) flag over-sized or undersized ducts. Animated particles show airflow direction and relative speed in each segment.
