The pressure at the stagnation point, often denoted as , refers to the pressure that a fluid experiences when it is brought to a complete stop in a flow field, typically due to an obstacle or surface. The stagnation point is where the fluid velocity is zero, and it’s also known as the “stagnation point pressure.”Â
NOTE : p0,2 is the total pressure behind the normal shock, then ps = p0,2
- Stagnation pressure (ps) in N/m^2
- Ratio of total pressure behind the normal shock to static pressure (p0,2/p1)
- Static pressure (p1) in N/m^2
