The “force per unit span acting on the bottom surface of the wedge,” denoted as F3′, refers to the aerodynamic force experienced by a unit length of the lower surface of a wedge-shaped object due to fluid flow interactions. This force is primarily a result of the pressure distribution and shear forces on the bottom surface of the wedge as the fluid flows over it.Â
- Ratio of static pressure at the bottom surface of the wedge to the static pressure at the bottom of the wedge (p3/p1)
- Static pressure at the bottom of the wedge (p1) in N/m^2
- Length of the face of the wedge (l) in m
- Force per unit span (F3′) in N/m
