Shock Wave in the Beirut Explosion: Theory and Video Analysis
Adam J. Czarnecki, Andrzej Czarnecki, Raquel Secrist, and Julia Willsey
TL;DR
This paper combines theoretical analysis and video data to study the shock wave from the 2020 Beirut explosion, validating the non-linear shock theory with real-world video evidence.
Contribution
It introduces a detailed theoretical framework for weak shock waves and validates it through frame-by-frame video analysis of the Beirut explosion.
Findings
The Landau-Whitham formula accurately predicts shock layer thickness.
Video analysis confirms the non-linear shock theory.
The study provides a rare visual validation of shock wave theory.
Abstract
Videos of the 2020 Beirut explosion offer a rare opportunity to see a shock wave. We summarize the non-linear theory of a weak shock, derive the Landau-Whitham formula for the thickness of the overpressure layer and, using frame-by-frame video analysis, we demonstrate agreement of data and theory.
