The performance of the NREL S807 airfoil is experimentally determined via wind tunnel testing. The tests are conducted at Reynolds numbers of 0.5, 1.0, and 1.5 10⁶, with a clean surface, with two ...

Bioinspired vortex generators increase airfoil lift, decrease drag Date: February 7, 2018 Source: Harvard John A. Paulson School of Engineering and Applied Sciences Summary: ...

"These shark-inspired vortex generators achieve lift-to-drag ratio improvements of up to 323 percent compared to an airfoil without vortex generators," says August Domel, co-first author of the paper.

A vortex generator placed at the front corner slices through the boundary layer right at its head, creating a spiral of air that mixes high velocity air into the boundary layer. This injection of high ...

A finite vortex method was developed based on the Kutta condition of pressure difference at the trailing edge of an airfoil aiming at the analysis and prediction of hydrodynamic load and wake field of ...
