Abstract

The use of computational fluid dynamics for external aerodynamic applications has been a key tool for aircraft design in the modern aerospace industry. In the last decades, Wall-Modeled Large-Eddy Simulation (WMLES) has gained momentum as a cost-effective approach for both scientific research and industrial applications. In this talk, we discuss the performance of WMLES for external aerodynamic applications, with emphasis on realistic commercial aircrafts. We examine the performance of WMLES for predicting the mean flow features, forces, and the trailing edge separation on the NASA Juncture Flow and the JAXA Standard Model in high-lift configuration. We also discuss some of the current challenges of WMLES to become a design tool for the aerospace industry. The vision presented will be motivated by discussions in previous reports and AIAA workshops, but especially by the experience acquired at the Center for Turbulence Research during the four last years.
