value: around the airfoil
type: LOCATION
value: at the trailing edge
type: LOCATION
Source sentences:
text: If the pressure on a closed surface is a constant, there is no net force produced because the summation of the directions of the normal adds up to zero.
text: Since the pressure is constant, we can also conclude that the sum of the normals to the surface, summed all around a simple closed surface, will be zero.
text: Another formulation is that the pressure must be continuous at the trailing edge.
text: As for an airfoil in a static fluid, the pressure is a constant all around the airfoil.
