Multidisciplinary Applications of Detached-Eddy Simulation to Separated Flows at High Reynolds Numbers (Challenge 92)

Abstract

The current effort develops and demonstrates the application of high resolution turbulence modeling to flight mechanics and aeroelasticity of air vehicles at flight conditions where the vehicle is experiencing massively separated flow fields. The effort has both a basic research component to aid in developing the method and an applied component where the method is used to demonstrate an ability to simulate current DoD aircraft issues in flight mechanics and aeroelasticity. The high resolution turbulence method is a hybrid Reynolds Averaged Navier-Stokes (RANS) Large Eddy-Simulation (LES) method introduced by Spalart et al. in 1997 called Detached-Eddy Simulation (DES) implemented in an unstructured Navier-Stokes solver, Cobalt.
