A DNS of an incompressible fluid flow over a Backward Facing Step (BFS ) with an Expansion Ratio (ER ) equal to 2, ER = H/(H - h), has been performed. Where h and H represent the step and the outlet heights, respectively. A turbulent channel flow at

Airfoil Stall Simulations with Algebraic Delayed DES and Physically Based Synthetic Turbulence for RANS-LES Transition

Autor: Axel Probst, Rolf Radespiel, Daniela Gisele François

Publikováno v: 32nd AIAA Applied Aerodynamics Conference.

For accurate computations of massively separated flows, a variety of Detached Eddy Simulation (DES) approaches have been recently developed. The Algebraic Delayed Detached Eddy Simulation (ADDES) proved to be an efficient approach in performing a rel

A Modified Shielding and Rapid Transition DDES Model for Separated Flows

Autor: Da Lei, Hui Yang, Yun Zheng, Qingzhe Gao, Xiubo Jin

Publikováno v: Entropy, Vol 25, Iss 4, p 613 (2023)

In this paper, the major problems associated with detached eddy simulation (DES) (namely, modeled stress depletion (MSD) and slowing of the RANS to LES transition (RLT)) are discussed and reviewed, and relevant improvements are developed. A modified
