Compressible fluid dynamics

Compressible fluid dynamics studies how fluids like gases behave when their density can change significantly due to variations in pressure, temperature, or speed. Unlike liquids, which are nearly incompressible, gases can expand or compress, affecting flow characteristics such as shock waves and sound propagation. This field uses specialized equations to analyze phenomena in high-speed aerodynamics, jet engines, and atmospheric science. It helps us understand and predict how gases move and interact under different conditions, enabling the design of efficient aircraft, spacecraft, and industrial processes involving compressible fluids.
