| Abstract: | The icing problem affects the flight safety of aircraft,exploring the icing effect on aerodynamic performance for aircraft is very important.In the research,three different ice shapes are constructed:sharp-angled ice,blunt nosed ice and double horn ice.The multi-block technology was used to generate grid,the flows of icing models are simulated numerically by solving the Navier-Stokes equations.The results calculated are in good agreement with experimental data and show that our method is correct for the icing research. |
