Article dans une revue avec comité de lecture(Elsevier, 2019)Research on laminar-turbulent transition of wall-bounded parallel flows has usually focused on controlled scenarios where transition is triggered by perturbations having simple shapes and spectra. These disturbances strongly ...
-
Article dans une revue avec comité de lecture(IOP Publishing, 2016)Subcritical transition in plane Poiseuilleflow is investigated by means of aLagrange-multiplier direct-adjoint optimization procedure with the aim offinding localized three-dimensional perturbations optimally growing in a ...
-
Article dans une revue avec comité de lecture(Elsevier, 2016)In this paper we present a high-order density-based finite-volume framework for all-speed flows. The formulation is based on high-order variable reconstructions performed using Moving Least Squares approximations. In ...

Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2018)The sparse identification of nonlinear dynamics (SINDy) is a recently proposed data-driven modelling framework that uses sparse regression techniques to identify nonlinear low-order models. With the goal of low-order models ...

Article dans une revue avec comité de lecture(Elsevier, 2015)This paper presents a new sliding mesh technique for the computation of unsteady viscous flows in the presence of rotating bodies. The compressible Euler and incompressible Navier–Stokes equations are solved using a ...
-
Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2017)The onset of unsteadiness in a boundary-layer flow past a cylindrical roughness element is investigated for three flow configurations at subcritical Reynolds numbers, both experimentally and numerically. On the one hand, ...

Article dans une revue avec comité de lecture(IOP Publishing, 2016)Transition from steady state to intermittent chaos in the cubical lid-driven flow is investigated numerically. Fully three-dimensional stability analyses have revealed that the flow experiences an Andronov-Poincaré-Hopf ...
