VCE Overpressure β Baker-Strehlow-Tang
Combustion-energy scaling and Sachs-scaled distance (exact), then peak side-on overpressure from a flame-speed (Mach) blast curve, with structural/physiological damage thresholds.
β Safety-critical β screening; overpressure is a curve approximation. Energy scaling & damage thresholds are exact, but the dimensionless overpressure is read from a digitized-curve approximation of the BST charts and is order-of-magnitude only. Results are dominated by the flame-speed Mach number (congestion/confinement). For design use the published BST charts or Phast / FLACS with SME review β not for safety case submission or regulatory filing.
