The pressure in region two behind a compression wave, often denoted as , refers to the pressure of the fluid after it has passed through a compression wave (also known as a shock wave). Compression waves are characterized by a sudden increase in pressure, density, and temperature of the fluid. The pressure is the value of the fluid pressure in the region immediately behind the compression wave. It’s usually higher than the pressure of the freestream flow (before the shock) due to the compression effect caused by the shock wave.
- Pressure in region two behind the compression wave (p2) in N/m^2
- Ratio of pressure in region two to the total pressure in region two behind the compression wave (p2/p0,2)
- Ratio of total pressure in region two to the total pressure at region one (p0,2/p0,1)
- Ratio of total pressure at region one to the pressure upstream of wave (p0,1/p1)
- Pressure upstream of wave (p1) in N/m^2
