Oscillating Airfoil

This research paper presents the CFD analysis of oscillating airfoil during pitch cycle. Unsteady subsonic flow is simulated for pitching airfoil at Mach number 0.283 and Reynolds number 3.45 millions. Turbulent effects are also considered for this study by using K-ω SST turbulent model. Two-dimensional unsteady compressible Navier-Stokes code including two-equation turbulence model and PISO pressure velocity coupling is used. Pressure based implicit solver with first order implicit unsteady formulation is used. The simulated pitch cycle results are compared with the available experimental data.

Porous Walls

The compressible subsonic flow about an oscillating two-dimensional aerofoil in a wind tunnel with porous walls is considered. The porous wall is assumed to exhibit the property that the ratio of the normal velocity at the wall to the pressure drop across the wall is constant. The aerodynamic derivatives are found for quasi-steady pitching motion of the aerofoil. The dependence of the derivatives on Mach number and wall porosity is displayed graphically.

SummaryThe compressible flow past an oscillating two-dimensional aerofoil in a wind tunnel with porous walls is considered, using linearised theory. The porous wall is assumed to have the property that the ratio of the normal velocity at the wall to the pressure drop across the wall is constant. Transform theory is used to find the supersonic longitudinal stability derivatives, and an extension of Possio's integral equation for the quasi-stationary case in subsonic flow.
