A Study on Discrete Frequency Noise from a Symmetrical Airfoil in a Uniform Flow
에어포일 이산소음 특성에 관한 연구
Abstract
The flow field around a symmetrical airfoil in a uniform flow under the generation of noise was studied by experiments and numerical simulation. The experiments are conducted by visualizing the surface flow over the airfoil with a shear-sensitive liquid-crystal coating and by measuring the instantaneous velocity field around the trailing edge of the airfoil. The numerical simulation was carried out by LES. (omitted)
