Article dans une revue avec comité de lecture(Elsevier, 2014)The convergence of Fourier-based time methods applied to turbomachinery flows is assessed. The focus is on the harmonic balance method, which is a timedomain Fourier-based approach standing as an efficient alternative to ...

Article dans une revue avec comité de lecture(Elsevier, 2014)In this paper we are concerned with obtaining estimates for the error in Reynolds-Averaged Navier-Stokes (RANS) simulations based on the Launder-Sharma k−ε turbulence closure model, for a limited class of flows. In particular ...

Article dans une revue avec comité de lecture(Elsevier, 2014)The turbulence closure model is the dominant source of error in most Reynolds-Averaged Navier–Stokes simulations, yet no reliable estimators for this error component currently exist. Here we develop a stochastic, a posteriori ...

Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2015)In this work it is shown that hairpin vortex structures can be the outcome of a nonlinear optimal growth process, in a similar way as streaky structures can be the result of a linear optimal growth mechanism. With this ...

Article dans une revue avec comité de lecture(Elsevier, 2015)We evaluate here three hemodynamic models used for the numerical simulation of bare and stented artery flows. We focus on two flow features responsible for intra-stent restenosis: the wall shear stress and the re-circulation ...

Article dans une revue avec comité de lecture(Ethan Publishing Company, USA, 2015)The adoption of counter-rotating stages for propellers, axial-flow pumps and low-speed fans has opened a way to design high performance and compact turbomachines in various industrial domains, leading to potentially high ...

Article dans une revue avec comité de lecture(Cambridge University Press (CUP), 2015)Transition to turbulence in shear flows is often subcritical, thus the dynamics of the flow strongly depends on the shape and amplitude of the perturbation of the laminar state. In the state space, initial perturbations ...
