    Abstract

    Three-dimensional unsteady Reynolds-averaged Navier-Stokes computations are performed for the flow past a pure plunging rectangular wing. Implicit RANS solver used for obtaining time-accurate solution is based on finite volume nodal point spatial discretization scheme with dual time stepping. The algebraic eddy viscosity model due to Baldwin and Lomax was used for turbulence closure. The aim of this work was to validate the IMPRANS solver for heaving bodies and understand the flow field around them. The results are obtained in the form of aerodynamic coefficients, thrust coefficient and propulsion efficiency and are compared with the available data in the literature.
