Abstract
AbstractThe turbulent flow around a delta wing at incidence is simulated numerically using a finite-volume Navier-Stokes method. The numerical simulation makes use of a simple algebraic turbulence model. The influence of grid refinement is investigated. The more realistic wing-body configuration with round leading edge is used to discuss the influence of the position of the transition line and to compare experimental and numerical data to validate the numerical method. The topological structure of the flow is discussed. An explanation is given for the low particle density area close to the primary vortex as it is visualised by laser light-sheet technique in the experiment. Results for a close coupled delta-wing-canard configuration are discussed.
