) is a thermodynamic property, defined as the square root of the partial derivative of pressure with respect to density at constant entropy ( In (
These are thin regions of high irreversibility. Thermodynamically, a shock wave converts kinetic energy into internal energy (heat), resulting in a sharp entropy rise. The Dynamics and Thermodynamics of Compressible...
Constrains the direction of flow processes, dictating that entropy must remain constant (isentropic) or increase (as seen across shock waves). Thermodynamics and the Speed of Sound ) is a thermodynamic property, defined as the
