High order discontinuous finitevolume/finiteelement method for CFD applications
(20141231)The proposed method naturally merges the desirable conservative properties and intuitive physical formulation of the widely used finitevolume (FV) technique, with the capability of local arbitrary highorder accuracy and ... 
Highorder mixed weighted compact and noncompact scheme for shock and small length scale interaction
(20131231)It is critical for a numerical scheme to obtain numerical results as accurate as possible with limited computational resources. Turbulent processes are very sensitive to numerical dissipation, which may dissipate the small ... 
Hydrodynamic identification of NAUTILUS FOWT platform from small scale tests
(2019)A smallscale tank test campaign of the NAUTILUS offshore wind floating semisubmersible platform was held at the Ifremer Deep Water Basin within the framework of the MaRINET 2 project. The support structure consists in ... 
Hydrodynamics of spike proteins dictate a transportaffinity competition for SARSCoV2 and other enveloped viruses
(20221201)Many viruses, such as SARSCoV2 or Influenza, possess envelopes decorated with surface proteins (a.k.a. spikes). Depending on the virus type, a large variability is present in the surfaceproteins number, morphology and ... 
Identification of defects originated during the filling of cast pieces through particles modelling
(20141231)In casting processes, strong recirculation zones may trap air, gases and strip particles of sand off the mold affecting seriously the quality of the cast pieces. Especially during the filling of molten pieces with large ... 
Lagged and instantaneous dynamical influences related to brain structural connectivity
(20151231)Contemporary neuroimaging methods can shed light on the basis of human neural and cognitive specializations, with important implications for neuroscience and medicine. Indeed, different MRI acquisitions provide different ... 
Layout Optimisation of Wave Energy Converter Arrays
(20170824)This paper proposes an optimisation strategy for the layout design of wave energy converter (WEC) arrays. Optimal layouts are sought so as to maximise the absorbed power given a minimum qfactor, the minimum distance between ... 
Mesoscopic modelling and simulation of espresso coffee extraction
(2019)A mesoscopic model for the simulation of espresso extraction based on the Smoothed Particle Hydrodynamics method is presented. The model incorporates some essential features such as bimodal granulometry (finescoarses) of ... 
Mesoscopic simulations of inertial drag enhancement and polymer migration in viscoelastic solutions flowing around a confined array of cylinders
(20220701)We study the flow around a periodic array of cylinders using a mesoscopic viscoelastic fluid that mimics polymeric solutions. We model our fluid employing a novel mesoscopic method based on Smoothed Dissipative Particle ... 
Metallic microswimmers driven up the wall by gravity
(20210721)Experiments on autophoretic bimetallic nanorods propelling within a fuel of hydrogen peroxide show that tailheavy swimmers preferentially orient upwards and ascend along inclined planes. We show that such gravitaxis is ... 
Modeling swelling effects during coffee extraction with smoothed particle hydrodynamics
(20220401)It is commonly assumed that coffee particles swell during filtration, but it has not been clarified how different degrees of swelling affect the extraction. In this article, we propose a grain swelling model to investigate ... 
Modeling the effect of flowinduced mechanical erosion during coffee filtration
(202109)The espresso extraction process involves a complex transport inside a geometrychanging porous medium. Large solid grains forming the majority of the porous medium can migrate, swell, consolidate and they can also ... 
Molecular Dynamics Test of the StressThermal Rule in Polyethylene and Polystyrene Entangled Melts
(20200203)Anisotropic thermal transport induced by deformation and the linear relation between the thermal conductivity and stress tensors, also known as the stressthermal rule (STR), are tested via molecular dynamics simulations ... 
Mooring system monitoring of offshore renewable energy floating platforms
(2019)An appropriate schedule of the operations for the maintenance (both long and short term) of offshore renewable energy devices can be a crucial key factor for assessing the economic viability of marine energy projects. ...
