Variation of leading-edge suction during stall for unsteady aerofoil motions

S Narsipur, P Hosangadi, A Gopalarathnam… - Journal of Fluid …, 2020 - cambridge.org
The suction force at the leading edge of a round-nosed aerofoil is an important indicator of
the state of the flow over the leading edge and, often, the entire aerofoil. The leading-edge …

A variational theory of lift

C Gonzalez, HE Taha - Journal of Fluid Mechanics, 2022 - cambridge.org

A minimization principle for incompressible fluid mechanics

H Taha, C Gonzalez, M Shorbagy - Physics of Fluids, 2023 - pubs.aip.org
Most variational principles in classical mechanics are based on the principle of least action,
which is only a stationary principle. In contrast, Gauss' principle of least constraint is a true …
