Blast wave scaling

WebA new approach to scaling blast wave instabilities is developed. When applied to the Rayleigh-Taylor case, unique scaling laws for explosion energy and density are derived. Connections with earlier scaling theory and turbulence are established. The validity of applying these scaling laws in the laboratory is demonstrated. WebMay 13, 2024 · A new dimensional analysis was developed to study the propagation of shock waves. The new analysis unifies the scaling for the air blasts and underwater blasts through the definition of new length, time, and pressure scales. The shock wave …
