The Stability of Wakes of Floating Wind Turbines
Vitor G. Kleine, Lucas Franceschini, Bruno S. Carmo +2
Floating offshore wind turbines (FOWTs) are subjected to platform motion induced by wind and wave loads. The oscillatory movement trigger vortex instabilities, modifying the wake s…
Evaluating the accuracy of the actuator line model against blade element momentum theory in uniform inflow
Luoqin Liu, Lucas Franceschini, Daniel F. Oliveira +3
We evaluate the accuracy of the actuator line model (ALM) approach by performing simulations for the NREL~5~MW wind turbine in uniform inflow using three large eddy simulation code…
Full waveform inversion using triangular waveform adapted meshes
Keith J. Roberts, Alexandre Olender, Lucas Franceschini +3
In this article, continuous Galerkin finite elements are applied to perform full waveform inversion (FWI) for seismic velocity model building. A time-domain FWI approach is detaile…
Mean- and unsteady-flow reconstruction with one or two time-resolved measurements
Lucas Franceschini, Denis Sipp, Olivier Marquet
In this article, we propose a methodology to reconstruct, in a single step, the mean- and unsteady properties of a flow from very few time-resolved measurements. The procedure is b…
Identification and reconstruction of high-frequency broadband fluctuations in a turbulent flow exhibiting low-frequency deterministic motions
Lucas Franceschini, Denis Sipp, Olivier Marquet +2
The turbulent flow around a squared-section cylinder at exhibits both a low-frequency Vortex-Shedding (VS), a common feature of all bluff-body flows, and high-frequency…
Mean-flow Data Assimilation based on minimal correction of turbulence models: application to turbulent high-Reynolds number backward-facing step
Lucas Franceschini, Denis Sipp, Olivier Marquet
In this article, we provide a methodology to reconstruct high-Reynolds number turbulent mean-flows from few time-averaged measurements. A turbulent flow over a backward-facing step…
