Atmospheric Physics

Wind Velocity (Vector) 0.5 m/s

Ambient Air Temperature 22 °C

CEW Probe & Arc Settings

Probe Arc Energy Gap 25 mm

CEW Arc Voltage Output 50 kV

Explosive Envelope Legend

Lean (<1.4% LEL)

Explosive (1.4-7.6%)

Rich (>7.6% UEL)

CEW Spark Gap

Physics Basis: Gasoline vapor is flammable when mixed in air between its Lower Explosive Limit (1.4% / 14,000 PPM) and Upper Explosive Limit (7.6% / 76,000 PPM). Electrical arcs exceeding minimum ignition energy (~0.25 mJ) inside this envelope ignite immediate local thermal runaway.
