). This field is governed by the intersection of classical fluid mechanics and thermodynamics, as the kinetic energy of high-speed flow is inextricably linked to internal energy and temperature changes. The Governing Equations
), the fluid moves faster than the information-carrying pressure waves, leading to the formation of shock waves—discontinuous regions where pressure, temperature, and density rise abruptly while velocity drops.

), pressure waves travel faster than the fluid, allowing the flow to "feel" obstacles ahead and adjust smoothly. In ( Dynamic Phenomena: Shocks and Expansion ), pressure waves
Relates velocity and density, ensuring mass is neither created nor destroyed within a control volume. The interplay of dynamics and thermodynamics is most
), which bridges the gap between mechanical properties (pressure) and thermal properties (temperature).
The interplay of dynamics and thermodynamics is most evident in two phenomena:
