Computation of Flow around a Rotating Flying Disk

The flow around a rotating disk placed in a uniform stream is simulated numerically by solving the incompressible NavierStokes equations. The overlaid grid system, the pair of a cylindrical grid and a vertical grid, has been implemented to compute the flow around the whole disk. Third order upwind scheme is employed since it has produced reasonable results also in turbulent high Reynolds number flows. The nature of the boundary layer formation on the moving disk surface is investigated, and the effects of the advance ratio, angle of attack and Reynolds number on the flow fields are examined and compared with experiments
