Detached-Eddy Simulation (DES) is a hybrid Reynolds Averaged Navier-Stokes (RANS)/Large-Eddy Simulation (LES) model.
The DES model was first proposed in 1997 by Spalart et al. [1] based on the Spalart-Allmaras RANS model and
it is commonly referred to as DES97.

I've summarized DES models available in OpenFOAM in the following post:
