| Abstract: | An immersed boundary method is applied to the numerical simulation of the flow past a clean/iced NACA0012 airfoil. In this paper, we solved two dimension imcompressible Reynolds-Averaged Navier-Stokes equations with SIMPLEC method. One equation turbulence modle, Spalart-Allmaras turbulence model, is used in the numerical procedure. Good agreement is found between the present numerical results and previous experimental work. |
