 Pierre Henri Hugoniot

Pierre-Henri Hugoniot was a French physicist and engineer known for his contributions to the understanding of shock waves and fluid dynamics. He is best known for formulating the Hugoniot equations, which describe the relationships between pressure, temperature, density, and velocity in systems undergoing shock waves, particularly in gases and liquids. Hugoniot's work played a significant role in the field of high-pressure physics and is essential in areas like astrophysics, material science, and explosion physics.
