Investigation of Airfoil Oscillation on Aerodynamic Coefficients with an Accurate Algorithm

In this study we introduce and validate an algorithm for simulating of flow field over moving boundaries where there are transverse cylinder and flapping airfoil. The governing equations are presented in arbitrary Lagrangian-Eulerian approach. We use finite element shape functions to approximate pressure and diffusion fluxes and finite volume to satisfy geometric and flow conservation laws. Our results show a good accuracy with large time steps and coarse meshes. The changing in oscillation parameters causes considerable effects on aerodynamic coefficients.
