Exergy analysis and improvement in inclined shock waves and rayleigh flows

It is possible to define a shock wave in physics as a type of wave traveling much faster than the local speed of sound in a fluid. Like a normal wave, a shock wave carries energy and can propagate together through a medium. It can also be characterized by a sudden, almost discontinuous change in pressure, temperature, and density of the medium. When looking at the Oblique Shock Wave; Oblique shocks mostly occur where the supersonic current turns inward. Normal shock can be said to be a special case of oblique shock. While the Mach number decreases while passing the oblique shock wave, the current does not go down to the subsonic regime. Pressure, temperature and density show an increase. Exergy is defined as an indicator of the availability of the potential energy contained in a thermodynamic system with respect to any reference state. Exergy is also expressed as the maximum amount of useful work that can be obtained theoretically, after deducting the energy that becomes unusable because of the entropy formed, if the system maintains equilibrium with the environment because of a reversible process. In system energy, exergy is defined as energy free from entropy.
