Rankine-Hugoniot conditions

The Rankine-Hugoniot conditions are mathematical equations that describe how physical properties like pressure, density, and velocity change across a shock wave—a sudden, powerful disturbance in a medium like air or water. They ensure the conservation of mass, momentum, and energy across the shock, providing a way to predict how these properties suddenly jump from one state to another. In essence, they help us understand and calculate the behavior of shock waves in various systems, such as explosions, supersonic flows, or astrophysical phenomena.
