Thin airfoil theory is the basis for an airflow analysis technique that relates the coefficient of life with the angle of attack (AOA). However, if it can be assumed that airfoil thickness is infinitesimal and the wingspan is very long – infinitely so – then incompressible, inviscid flow can be analyzed using thin airfoil theory, which is defined below. Analyzing fluid flow over airfoils can be complex and computationally expensive. However, cambered airfoils are used most often, as they generate greater lift due to the upper section being more convex than the lower. They may be symmetrical, where the upper and lower sections are the same size and shape. What Is the Thin Airfoil Theory?Īirfoils, also referred to as aerofoils, come in many shapes and sizes.
If a simple solution is desired and height can be mostly neglected, consider using the thin airfoil theory.
When studying airflow around airfoils, several methods can be used, depending on whether the flow is compressible, incompressible, and/or inviscid. There is the all-purpose Navier-Stokes equation that is used to study oil and gas through pipelines and fluid flow in thermo-, hydro- and aerodynamics. There are so many tools available to solve engineering problems involving fluid mechanics.
