摘要

Unstructured triangular grid is used for simulating directly unsteady incompressible flows along a multi-element airfoil. The finite volume method is developed newly for dicretizingng the vorticity transport and Poisson equation which is tuned for computing flows in multiply-connected domain. The angle of attack 25 degrees of Air-bus three-elemnts airfoil is adopted for low Reynolds number case for validating the present method. The complex unsteady flow is realized and the grid has to be condensed, in order to obtain a converged solution, where the flow changes drastically. It is shown that the lift coefficient depends on the Reynolds number and the present method is effecitive.
