Isolated Gust Generation for the Investigation of Airfoil-Gust Interaction [PDF]
, 2016 As part of an effort to examine the impact of vortical gusts on airfoils, a simple gust generator has been built and investigated. This consists of a heaving at plate capable of following a specifed transverse trajectory across a water tunnel.

Effects of heaving and pitching motions on underside aerodynamics of a sedan vehicle
Journal of Fluid Science and Technology, 2019 Unsteady pressure distributions around a simplified sedan automobile model were investigated by conducting dynamic wind-tunnel testing using the newly developed forced oscillating apparatus, HEXA-X3, which can produce 6-degrees-of-freedom motion.

Journal of Glaciology, 2010 AbstractThe deformation of the ground surface that is produced by frost heave has motivated almost a century of concerted laboratory, field and theoretical studies. Well before the development of equipment capable of resolving the microscopic films that support liquid transport towards growing ice lenses, early investigators predicted their occurrence ...

Scaling the propulsive performance of heaving and pitching foils
, 2017 Scaling laws for the propulsive performance of rigid foils undergoing oscillatory heaving and pitching motions are presented. Water tunnel experiments on a nominally two-dimensional flow validate the scaling laws, with the scaled data for thrust, power ...
