Simulation of Maximum Lift Using URANS for a High-Lift Transport Configuration

摘要

Maximum lift prediction for a modern realistic transport high-lift configurations using a Computational Fluid Dynamics (CFD) based method still poses a significant challenge. The flow around a high-lift aircraft configuration can be characterized by a number of physical flow features such as flow separation, laminar/ turbulent boundary layers, wakes of wing elements, vortical flows structures, vortex break down, but also deformation of the wing and its components. The accurate modelling of these individual physical features require the development, verification and validation of specific CFD algorithms. This paper focuses only on one of these algorithms, namely a time-integration algorithm.
