The total enthalpy of the freestream, denoted by h0, is also known as the stagnation enthalpy or total enthalpy. It is defined as the sum of the static enthalpy (associated with the temperature and static pressure at that point) and the enthalpy associated with the dynamic pressure or velocity. Total enthalpy (h0) in J/kg Freestream enthalpy

The ratio of density behind the wave to the freestream density is a parameter that is used to describe the behavior of a normal shock wave. A normal shock wave is a type of shock wave that occurs when a supersonic flow encounters an obstacle and slows down to subsonic speeds. Specific heat ratio (𝛾)

An oblique shock angle is the angle between the direction of the supersonic flow and the shock wave that forms when the flow encounters a corner or a wedge that deflects the flow. The oblique shock angle depends on the upstream Mach number, the specific heat ratio of the fluid, and the deflection angle of
