Formation mechanism and microstructural characteristics of a body-centered cubic phase in 3D printed 316L–CuCrZr multi-material structures, combining laser powder bed fusion with foils

Roland Logé, Cyril Cayron, Jamasp Jhabvala, Seyed Amirmohammad Jamili

Additive manufacturing of 316L/CuCrZr multi-material metallic structures has recently attracted significant attention, due to the ideal combination of structural and thermal/electrical properties. In this work, a unique multi-phase microstructure was produ ...

Conditions for the local arrest of a hydraulic fracture by a region of larger toughness

Brice Tanguy Alphonse Lecampion

We investigate the conditions for the local arrest of a hydraulic fracture encountering a region of larger toughness. The propagation of a hydraulic fracture strongly depends on the ratio between the energy dissipated in the creation of new fracture surfac ...

Buoyancy-tilted Shear Layers and Coherent Structures in Hyperpycnal River Plume Plunging

David Andrew Barry, Ulrich Lemmin, Haoran Shi

Shear layers and corresponding Kelvin Helmholtz-type Coherent Structures (KHCS) can be generated by rivers discharging into laterally-unconfined quiescent open water bodies (e.g., lakes). When the river discharge has a greater density than the receiving wa ...

On the duration of flood hydrograph using the Compound Poisson Process approximation

Paolo Perona, Giulio Calvani

River engineering projects are usually designed based on the peak discharge concept. However, some river processes depend on the shape and duration of the flow hydrograph, and their modelling is particularly relevant for designing protection and retention ...

On the difficulty of determining Kármán "constants" from direct numerical simulations

Peter Monkewitz

The difficulty of determining the slope of the famed logarithmic law in the mean velocity profile of wall-bounded turbulent flows, the inverse of the K & aacute;rm & aacute;n "constant" kappa, from direct numerical simulations (DNS) is discussed for channe ...

Additive Fabrication of Functional Microfluidic Devices

Mustafa Mohieldin Fadlelmula Fadlelseed

In the age of smart systems, artificial intelligence, and personalized devices, the need for effective methods to facilitate multifunctionality integration has become a necessity. One of the fields that boosts the efforts of multifunctionality integration ...

Coating thickness prediction for a viscous film on a rough plate

François Gallaire, John Martin Kolinski, Giuseppe Antonio Zampogna, Lebohang Molefe

Surface roughness significantly modifies the liquid film thickness entrained when dip coating a solid surface, particularly at low coating velocity. Using a homogenization approach, we present a predictive model for determining the liquid film thickness co ...

A Fast Hybrid Pressure-Correction Algorithm for Simulating Incompressible Flows by Projection Methods

Jiannong Fang

To enforce the conservation of mass principle, a pressure Poisson equation arises in the numerical solution of incompressible fluid flow using the pressure-based segregated algorithms such as projection methods. For unsteady flows, the pressure Poisson equ ...

A stable loosely-coupled scheme for cardiac electro-fluid-structure interaction

Alfio Quarteroni

We present a loosely coupled scheme for the numerical simulation of the cardiac electrofluid-structure interaction problem, whose solution is typically computationally intensive due to the need to suitably treat the coupling of the different submodels. Our ...

A revised gap-averaged Floquet analysis of Faraday waves in Hele-Shaw cells

Baptiste Kellian Jouron, François Gallaire, Alessandro Bongarzone

Existing theoretical analyses of Faraday waves in Hele-Shaw cells rely on the Darcy approximation and assume a parabolic flow profile in the narrow direction. However, Darcy's model is known to be inaccurate when convective or unsteady inertial effects are ...

Influence of the shear stress on fine sediment exchanges with the substrate using UVP measurements

Giovanni De Cesare, Romain Maxime Dubuis

The dynamic of fine sediment in rivers is closely related to the interactions between fine particles, the riverbed and the flow conditions. The accumulation of fine sediment in the riverbed reduces vertical water exchanges and can have detrimental effects ...

A comprehensive mathematical model for cardiac perfusion

Alfio Quarteroni, Francesco Regazzoni, Christian Vergara

The aim of this paper is to introduce a new mathematical model that simulates myocardial blood perfusion that accounts for multiscale and multiphysics features. Our model incorporates cardiac electrophysiology, active and passive mechanics, hemodynamics, v ...

Wind Turbine Wakes in Active Yaw Control: Numerical and Theoretical Studies

Mou Lin

In this thesis, we explore the best practice of simulating the wakes of the turbines under active yaw control (AYC) using large-eddy simulation (LES). In the first study, we validate the blade-element actuator disk model (ADM-BE) for a yawed wind turbine. ...

Dynamic stall characterisation and control for vertical-axis wind turbines

Sébastien Le Fouest

According to the International Energy Agency, the global net-zero emissions objective requires the installed wind power capacity to increase 11-fold between 2020 and 2050. The scientific community has recently voiced concerns about the logistic feasibility ...

Mesh d-refinement: a data-based computational framework to account for complex material response

Jean-François Molinari, Antonio Joaquin Garcia Suarez, Sacha Zenon Wattel

Model-free data-driven computational mechanics (DDCM) is a new paradigm for simulations in solid mechanics. The modeling step associated to the definition of a material constitutive law is circumvented through the introduction of an abstract phase space in ...

X-ray radiography 4D particle tracking of heavy spheres suspended in a turbulent jet

Edward Carlo Giorgio Andò

The suspension of a heavy sphere by an upward jet is a classical fluid mechanics experiment to demonstrate the fluid forces acting on an object. In the range of the parameter space where the sphere can be suspended, the dynamics can either be regular, i.e. ...
