Effect of Various Parameters on the Flapping Motion of an Aerofoil
並列摘要
Unsteady Reynolds-averaged Navier-Stokes (RANS) computations are presented for the flow past a flapping NACA 0012 aerofoil to study the effect of various motion parameters on the propulsive efficiency and thrust coefficient. The RANS solver used to obtain the timeaccurate solutions is based on an implicit dual time stepping scheme with finite volume nodal point spatial discretization. The algebraic eddy viscosity model due to Baldwin and Lomax is used for the turbulence closure. The motion parameters considered are reduced frequency, amplitude of the pitch and plunge motions and phase shift between them. The computed results compare well with the available data in the literature.
