Plunging Airfoil Load Characteristics Equipped with Gurney Flap
Numerous experiments have been conducted on plunging Eppler 361 airfoil in a subsonic wind tunnel. The experimental tests involved measuring the surface pressure distribution over the airfoil at Re=1.5×105. The airfoil was equipped with Gurney flap(heights of 2.6, 3.3 and 5% chord) and plunged at 6cm amplitude. The unsteady aerodynamic loads were calculated from the surface pressure measurement...
متن کاملEffect of a Gurney Flap on the Lift of an Airfoil
The problem investigated in this experiment was which height of Gurney Flap gives the best lift improvement on an airfoil without increasing drag. The Gurney Flaps' heights are determined as a percentage of the airfoil's chord length. The hypothesis is that a Gurney Flap will produce the best lift to drag ratio when its height is two percent of the airfoil's chord length. The hypothesis was tes...
متن کاملComputational Investigations on the Effects of Gurney Flap on Airfoil Aerodynamics
The present study comprises steady state, two-dimensional computational investigations performed on NACA 0012 airfoil to analyze the effect of Gurney flap (GF) on airfoil aerodynamics using k-ε RNG turbulence model of FLUENT. Airfoil with GF is analyzed for six different heights from 0.5% to 4% of the chord length, seven positions from 0% to 20% of the chord length from the trailing edge, and s...

15 صفحه اولNumerical Investigation of S822 Wind Turbine Airfoil
We carried out direct numerical simulations of the flow past a two-dimensional S822 wind turbine blade section at a chord Reynolds number of Re=100,000 and an angle of attack of α = 5deg. Without blade rotation the separated boundary layer “rolls up” into spanwise vortices which then “break up” into smaller scale structures leading to transition to turbulence. Simulation results compare favorab...
