Numerical simulations of a transport-aircraft configuration

Abstract

An implicit low-cost Navier–Stokes solver combined with a multigrid algorithm and wall functions has been developed for efficient numerical simulations on a realistic wing-body aircraft configuration. A study of the behaviour of different transport-equation turbulence models is given. Comparisons are made with experimental data. The structure of the three-dimensional flow separation predicted by computations is described and its topological coherence is checked.
