The Vortex and Wing Lift [PDF]
, 2022 AbstractThe vortex is a necessary element of fluid motion for the generation of aerodynamic forces. For flight, lift balances the weight of an aircraft and the means for providing lift is the wing constructed to move oncoming air downward in a controlled fashion.

Numerical Simulation on Vortex Shedding from a Hydrofoil in Steady Flow
Journal of Marine Science and Engineering, 2020 This paper presents a numerical modeling procedure for the idealization of vortex shedding effects in the wake flow field of a NACA0009 hydrofoil. During the simulation, the lift and drag acting on the hydrofoil were monitored, and the vortex-shedding ...
