“Γinput” refers to the updated or modified value of circulation around a specific spanwise station along the wing of an aircraft or any lifting surface. Circulation is a fundamental concept that quantifies the net rotational motion of air particles around a closed path, often associated with the creation of lift.
- Γinput is the updated value of circulation.
- Γold is the previous or current value of circulation.
- Γnew is the new value of circulation.
- D is the damping factor, which determines the influence of the new value on the update. It typically lies between 0 and 1.
