内容記述 | This paper presents current status and issues of aircraft drag prediction using numerical methods based on Reynolds-averaged Navier-Stokes equations (RANS) in JAXA. Several results on an airfoil and aircrafts show the prediction of aerodynamic drag is very sensitive to grid density and numerical schemes as well as transition in boundary-layer. Although state-of-the-art RANS CFD can not satisfy the requirement for aerodynamic design of aircrafts enough, it already provides almost the same reliability as wind tunnel tests in some cases. To overcome the issues in the prediction reliability, tighter cooperation between numerical and experimental methods is important besides efforts to improve numerical schemes and turbulence models. | |||||
