TL;DR: A hierarchy of low-dimensional Galerkin models is proposed for the viscous, incompressible flow around a circular cylinder building on the pioneering works of Stuart (1958), Deane et al. (1991), and Ma & Karniadakis (2002) as mentioned in this paper.

TL;DR: The MEGAFLOW project as mentioned in this paper is a cooperative effort involving the aircraft industry, the DLR and several universities to develop a dependable and efficient numerical tool for the aerodynamic simulation of complete aircraft in cruise as well as in take-off and landing configurations.

TL;DR: In this paper, phase averaged quantities were first obtained using the wall pressure signal on the cylinder as a trigger signal, and a POD analysis was then performed to extract the coherent motion and to compare this decomposition with that obtained by phase averaging.

TL;DR: In this paper, the entropy noise mechanism was investigated both experimentally and numerically on a generic test case, where electrical heating was used to generate non-isentropic perturbations in a spatially varying average flow field set by the geometrical boundary conditions of an axisymmetric convergent-divergent nozzle.

TL;DR: In this article, the predictive performance of explicit algebraic stress models (EASM) and large eddy simulation (LES) is compared to conventional BVM, LES and measurements.
