Pressure Coefficient
This information can be used to show that the pressure coefficient at a stagnation point is unity (positive one):
where:
- is pressure coefficient
- is static pressure at the point at which pressure coefficient is being evaluated
- is static pressure at points remote from the body (freestream static pressure)
- is dynamic pressure at points remote from the body (freestream dynamic pressure)
Stagnation pressure minus freestream static pressure is equal to freestream dynamic pressure; therefore the pressure coefficient at stagnation points is +1.
