Unsteady Flow past a Flapping Aerofoil\ud

Abstract: Unsteady flow computations are presented for\ud low speed Mach number flow past a combined pitching and\ud plunging aerofoil. The Implicit Reynolds-averaged\ud Navier-Stokes solver used for obtaining time-accurate\ud solutions is based on finite volume nodal point spatial\ud discretization scheme with dual time stepping. Results are\ud obtained in the form of aerodynamic coefficients, time –\ud averaged thrust coefficient and propulsion efficiency which\ud agree well with the available results.\u
