Milestone: Direct Fem-Simulation of Airflow around Complete Airplane
The first direct computational simulation of the flow of air around a complete airplane (DLR F11 high-lift configuration) has been performed by the CTLab group at KTH led by Johan Hoffman in the form of Direct Fem-Simulation (DFS). The simulation gives support to the new theory of flight developed by Hoffman and myself now under review by Journal of Mathematical Fluid Mechanics after initial rejection by AIAA. The milestone will be presented at 2nd AIAA CFD High Lift Prediction Workshop, San Diego, June 22-23 2013.
DFS is performed by computational solution using an adaptive residual-stabilized finite element method for the Navier-Stokes equations with a slip boundary condition modeling the small skin friction of air flow. DFS opens for the first time the possibility of constructing a realistic flight simulator allowing flight training under extreme dynamics, beyond the vision of AIAA limited by classical flight theory.
