Effect of Turbulence Intensity on Airfoil Flow: Numerical Simulations and Experimental Measurements
摘要
Abstract
Effect of the turbulence intensity of the oncoming stream on the aerodynamic characteristics of NACA-0012 airfoil was investigated by a direct numerical simulation. The numerical results were found to be consistent with the experimental measurements. Based on the finite spectral QUICK scheme, the simulation gets the high accuracy results. Both the simulation and experiment reveal that the airfoil stall does not exist for low turbulence intensity, however, occurs when the turbulence intensity increases sufficiently. Besides, the turbulence intensity has a significant effect on both the airfoil boundary layer and the separated shear layer.关键词
