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 […]

The “force per unit span acting on the top of the wedge,” denoted as F2′, refers to the aerodynamic force exerted on a unit length of the top surface of a wedge-shaped object that is exposed to a fluid flow. This force is generated due to the interaction between the fluid and the surface of

In aerodynamics, an “expansion wave over the top of the flat plate” refers to a specific flow phenomenon that occurs when a supersonic flow interacts with the upper surface of a flat plate. The “expansion wave over the bottom of the flat plate” refers to a specific flow phenomenon that occurs when a supersonic flow

The force per unit span (F2′) on the top surface of a wedge refers to the aerodynamic force exerted on a unit span length of the top surface of the wedge-shaped body when it is exposed to a fluid flow. This force is usually perpendicular to the direction of the incoming flow and can be

The Prandtl-Meyer angle (ν2) after a deflection at a wedge refers to the change in the Prandtl-Meyer angle due to the deflection of a supersonic flow around a wedge-shaped body or surface. The Prandtl-Meyer angle is a critical concept in supersonic aerodynamics that characterizes the angular deviation of the flow direction from a reference direction. 

The drag coefficient (cd​) for a flat plate is a dimensionless quantity that characterizes the aerodynamic drag or resistance experienced by the flat plate as it moves through a fluid medium. It provides a standardized measure of how effectively the flat plate’s shape and orientation affect the drag force.  Lift coefficient (cl) Angle of angle

The “drag per unit span” (D′) for a diamond-wedge airfoil refers to the aerodynamic force acting parallel to the direction of the oncoming airflow, per unit span length of the airfoil. This force represents the component of aerodynamic resistance that opposes the forward motion of the airfoil through the air.  Pressure on the top surface
