In order to validate the application of Large eddy simulation in the field of incompressible flow, the author used Large eddy simulation to compute 2-dimensional incompressible flows around an airfoil by software Fluent. In the beginning of computation, the paper prepared five types of mesh in order to check up the LES requiring for mesh. Then the author monitored lift coefficient and drag coefficient on the airfoil. The present results are compared with the experimental results. When the section angle of attack is low, the results of numerical simulation are very close to the experimental. However, at the attack angle of near stall condition there is some error. Large eddy simulation can simulate the origination and breaking off of the eddy very well. Strouhal number obtained is close to the theory. Validate the method of large eddy simulation by numerical simulation. |
