- The aerodynamics at near-stall conditions is particularly difficult to predict. This article introduces a formulation of Large Eddy Simulations with modelled wall-stress (WMLES) with limited damping of near-wall unsteadiness. It correctly captures the stall of a three-element airfoil and the lift of NASA’s Common Research Model. Industry leaders such as Rolls-Royce (Peer.Boehning@rolls-royce.com) are interested in this approach and have compared this model with existing alternatives with positive results (Innovate UK “ACAPELLA” project). This article precedes the 4th AIAA CFD High-Lift Workshop (2021) which will focus on WMLES of the NASA model, and is potentially a starting point for similar efforts.
