The pressure behind a shock wave, often denoted as , refers to the pressure of a fluid immediately after it has passed through a shock wave in a compressible flow. The pressure behind the shock wave is typically higher than the pressure upstream of the shock. This is because the shock wave slows down the fluid and compresses it, leading to an increase in pressure. The precise value of depends on the initial conditions of the flow and the characteristics of the shock wave.
- Pressure behind the shock (p2) in N/m^2
- Density behind the shock (𝜌2) in kg/m^3
- Specific gas Constant (R) in J/kg*K
- Temperature behind the shock (T2) in K
