Adaptation of Eddy-Viscosity Turbulence Models to Unsteady Separated Flow Behind Vehicles (2004, methodology): “The idea behind the DES model of Strelets (2001) is to switch from the standard SST-RANS model to an LES model in those regions where the turbulent length, Lt, predicted by the RANS model is larger than the local grid spacing.”
Assessment of hybrid RANS-LES formulations for flow simulation around the Ahmed body (2017, positive): “hybrid nature of DES is not linked with any specific turbulence model and the model employed in the present study is a variant based on the k − ω SST turbulence model proposed by Strelets [32].”
Differential equation-based wall distance computation for DES and RANS (2003, background): “adjacent walls. As discussed later, the Laplacian perhaps has the potential to lessen non-smoothness issues [ 25 ] associated with SA DES.”
Ten Years of Industrial Experience with the SST Turbulence Model (2003, methodology): “For FSST =0, the model of Strelets [10] is recovered.”
Zonal Detached Eddy Simulation of a Controlled Propulsive Jet (2007, methodology): “Among the successful or encouraging applications of this method, we can mention turbulent flows over various solid bodies like a backward-facing step and an aircraft landing gear truck [7], a sphere [8], and an F-15E at a 65-deg angle of attack [9].”
Laminar-Turbulent Transition of a Low Reynolds Number Rigid or Flexible Airfoil (2006, methodology): “The large-eddy simulation (LES) [38] and direct numerical simulation are also being employed to study laminar-turbulent transition.”
Assessment of Various Turbulence Models for Transitional Flows in an Enclosed Environment (RP-1271) (2009, background): “The DES-ke model solves two additional transport equations—one for subgrid-scale TKE and the other for turbulence dissipation rate ε. Similarly, the DES-SST model solves for subgrid-scale TKE and specific dissipation rate ω. Figure 16 shows that both the models successfully predicted the TKE profile”
Hybrid LES-RANS using synthesized turbulent fluctuations for forcing in the interface region (2006, methodology): “Hybrid LES-RANS is similar to DES (detached eddy simulations) (Spalart et al., 1997; Spalart, 2000; Strelets, 2001).”
A hybrid RANS-LES approach with delayed-DES and wall-modelled LES capabilities (2008, methodology): “In this work we use 4th-order centered approximation for the channel and hydrofoil flows and a weighted, 5th order upwind/4th order centered, scheme with a blending function dependent on the solution (Strelets, 2001; Travin et al., 2002) for the stalled airfoil and backward-facing step flows.”
