The present contribution focuses on the behavior of two RANS Reynolds stress turbulence models in the prediction of flow reversal occurring in turbulent wakes subjected to strong adverse pressure gradients. RANS results are compared to a high-fidelit

The numerical three-dimensional structural design of a large-displacement flexible morphing wing leading edge, otherwise known as a droop nose, is presented in this article. The droop nose is an essential component of a novel internally blown high-li

The present work focuses on the scale-resolving numerical simulation of an isolated jet-engine intake in presence of side wind. The computation was carried out with the DLR TAU code within the framework of the Rolls-Royce funded project FaNcI (Fan-Na

The paper presents a bilateral German-Russian project launched in 2017 and aimed at investigation of turbulent wakes in the presence of Adverse Pressure Gradient (APG). Such wakes are a common feature of high-lift wing flows near the maximum lift con

Results are presented of scale-resolving Zonal RANS-IDDES and pure RANS computations of a turbulent wake exposed to adverse pressure gradient. The RANS–IDDES is performed with the use of the NTS code of SPBPU, and the RANS computations are carried

We propose a hierarchy of low-dimensional proper orthogonal decomposition (POD) models for the transient and post-transient flow around a high-lift airfoil with unsteady Coanda blowing over the trailing edge. The modal expansion comprises actuation m
