Abstract

The unsteady flow over a sinusoidally oscillating NACA64A010 aerofoil in plunge is simulated numerically using a three dimensional Implicit Reynolds Averaged Navier Stokes Solver (IMPRANS) for subsonic and transonic Mach numbers. The solver used for obtaining the time-accurate solution is based on an implicit dual time stepping with finite volume nodal point spatial discretization scheme. Results for the subsonic and transonic cases compare well with the available experimental data, thus demonstrating the capability of the solver to provide useful unsteady pressure data for aeroelastic analysis.
