Computational Fluid Dynamics Analysis of Wind Tunnel Test for Natural Laminar Flow Airfoil
자연층류 익형 풍동시험 전산유체해석
Abstract
Wall correction method for wind tunnel test is reviewed and applied to the numerical experimental results obtained at the wind tunnel condition. The corrected lift coefficient agrees well with the reference data generated from the grid having very far boundary However the corrected drag coefficient presents some deviation from the reference data.
풍동시험의 벽면효과 보정방법이 풍동시험 조건에서 수행된 전산해석결과에 적용되었다. 보정을 마친 양력계수는 벽면이 없는 조건에서 수행된 전산해석 결과와 잘 일치하지만 보정된 항력계수는 벽면효과가 제거된 결과와 약간의 차이를 보인다.
