In this study, we performed numerical simulations of a 2-D laminar flow past an NACA0012 airfoil. The computation was run on the simulation code being developed to predict an aero-acoustic problem by using a highly accurate numerical method. For the verification of our code, the results are compared with the experimental data obtained in a similar flow configuration and also with an available numerical study. The detailed flow visualization is presented to understand the mechanism of the wake instability that results in vortex shedding., 資料番号: AA0063908013, レポート番号: JAXA-SP-07-026E}, pages = {41--44}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Numerical simulations of flow past a 2-D airfoil at a low Reynolds number}, volume = {JAXA-SP-07-026E}, year = {2008} }
