Mathematical Fluid Dynamics
Density change refers to the variation in mass per unit volume of a fluid as it undergoes different physical conditions, such as pressure and temperature changes. In the context of fluid dynamics, especially in compressible flow situations like shock waves, density change is crucial in determining how the fluid behaves under rapid pressure variations. It is particularly significant during events like normal and oblique shocks, where fluids can experience sudden transitions in velocity and thermodynamic properties.
