Fluid dynamics around a wind vane
WebJul 23, 2024 · Because the fluid follows curved paths around the airfoil, it is experiencing accelerations in various directions as it passes the airfoil. These accelerations are aligned with pressure gradients in the fluid. Webvane: [noun] a movable device attached to an elevated object (such as a spire) for showing the direction of the wind. one that is changeable or inconstant.
