Europe is seeking to reduce aircraft development and operating costs. To reach these objectives, the aeronautical industry will need improved CFD models based on a deeper understanding of the physics, acquired using the most advanced experimental and modelling methods. The WALLTURB project intends to make significant progress in the understanding and modelling of near-wall turbulence in boundary layers. It is the inner part of the boundary layer nearest the wall that is crucial in determining the skin friction drag and it is in this region that the present turbulence models are least reliable, most notably when the flow is close to separation or separated. A better understanding and modelling of this region is crucial. |
