Real-Time ALOHA and Dense Gas (SLAB) Atmospheric Dispersion Modeling
Core aerospace engineering and protocols for ALOHA Plume Dispersion Modeling.
The Dynamic Physics of Toxic Chemical Dispersion
Toxic industrial chemicals do not disperse uniformly: heavy gases like chlorine slump into low-lying riverbeds and basements, while changing winds bend toxic plumes toward schools or hospitals miles away.
Real-Time Continuous Dispersion Calculations
ResponseEvtol continuously couples live airborne gas readings with onboard 3D ultrasonic wind measurements. Running EPA-approved ALOHA and SLAB dispersion algorithms, the aircraft generates updated color-coded plume maps every 30 seconds, showing exactly where lethal concentrations will drift.
- EPA ALOHA Modeling: Calculating Immediately Dangerous to Life or Health (IDLH) boundaries.
- Dense Gas Slumping Physics: Modeling heavy chemical gases (chlorine, propane) that flow along ground contours.
- Dynamic Wind Integration: Recalculating plume drift as urban winds shift direction.
- Explosive Flammability Limits: Mapping the Lower Explosive Limit (LEL) zone to prevent spark ignition.
