Study on Flow Mechanism of a Morphing Supercritical Airfoil

A Numerical Study of Transonic Buffet on a Supercritical Airfoil

The steady/unsteady flow of the BGK No. 1 supercritical airfoil is investigated by the solution of the Reynolds-Averaged Navier-Stokes equations with a two-equation k-ω turbulence model. The dual-time stepping method is used to march in time. Two steady cases ( 71 . 0 = Ma , 396 . 1 = α and 71 . 0 = Ma , 0 . 9 = α ) and one unsteady case ( 71 . 0 = Ma , 97 . 6 = α ), both with a far-stream 6 10...

Aerodynamics of a Morphing Airfoil

The purpose of this research is to develop a MATLAB model which can calculate the aerodynamics, such as lift, drag, and pressure, on an airfoil as it changes shape. This model needs to be computationally efficient and should have reasonable accuracy. A constant strength doublet panel code, which takes thickness and camber distribution as inputs, is used to model the aerodynamics. This code has ...

Numerical Study of Transonic Buffet on a Supercritical Airfoil

The flow of the Bauer–Garabedian–Korn (BGK) No. 1 supercritical airfoil is investigated by the solution of the unsteady Reynolds-averaged Navier–Stokes equations with a two-equation lagged k–ω turbulent model. Two steady cases (M = 0.71, α= 1.396 deg and M = 0.71, α= 9.0 deg) and one unsteady case (M = 0.71, α= 6.97 deg), all with a far-stream Reynolds number of 20 × 106, are computed. The resu...
