근접 상호작용을 갖는 Canard-Wing-Body 형상의 점성유동 해석

Abstract

The full Navier-Stokes equations are solved for the flow about a coplanar close-coupled canard-wing-body configuration at a Mach number of 0.7 and at angles of attack of 4 and 12 degs using a second-order accurate finite difference scheme based on the Beam-Warming approximate factorization. The influence of canard on wing flow fields, including canard-wing vortex interaction and wing vortex breakdown, is discussed. Good agreements are obtained between the computation and the experimental measurement for the distributed surface pressures. The surface pressure contours and the particle trajectory simulations are presented.
