A wind tunnel investigation of a wing-tip trailing vortex
A 3 'x2' subsonic wind tunnel has been constructed and calibrated. The flow in the wind tunnel accelerates 6.1 % along the test section due to boundary layer growth. The potential core flow at both the entrance and exit locations is strongly uniform. The mean velocity varies .4% across the entrance …

Wind tunnel investigation of wind load on a ground mounted photovoltaic tracker
Wind loading is an important environmental factor to be considered in design of components and support structures of ground mounted photovoltaic tracker systems (PVT). Current understanding of action of wind on such systems is incomplete. Over the past decade, a number of investigations devoted to …

An experimental study of the aerodynamic characteristics of a wing in close proximity to a moving ground plane
A wind-tunnel investigation was conducted to determine the effect of ground proximity on the aerodynamic characteristics of a slender un-cambered DHM1TU rectangular wing of aspect ratio 3. A moving-belt ground plane and elevated aerodynamic balance facility were designed and installed in the UCT …

Exploratory experimental investigation of a wave propeller
A low-speed wind tunnel investigation was conducted to determine if a small secondary airfoil or wave propeller, oscillating in a rotary plunging motion, could significantly affect the airflow over a lifting airfoil surface to delay the onset of stall. The lifting airfoil shape was a NACA …

Experimental and Numerical Investigations on Aerodynamic Characteristics of Savonius Wind Turbine with Various Overlap Ratios
Savonius wind turbine is the simplest type of vertical axis rotor that has a relatively low efficiency. Operation of the Savonius wind turbine is based on the difference of the drag force on its semi-spherical blades, depending on whether the wind is striking the convex or the concave part of the …

The Effect of Surface Materials and Morphology on Wingsuit Aerodynamics
… and construction. The experiment was a low-speed wind tunnel investigation using a rigid wing with an aspect ratio of 2, a NACA 4418 airfoil cross section and a smooth, polished painted surface as a baseline. The baseline wing was modified by covering the upper and lower surfaces with various …
