Thermophysical Phenomena in Metal Additive Manufacturing by Selective Laser Melting: Fundamentals, Modeling, Simulation and Experimentation

, 2017
Among the many additive manufacturing (AM) processes for metallic materials, selective laser melting (SLM) is arguably the most versatile in terms of its potential to realize complex geometries along with tailored microstructure.

Homogenized lattice Boltzmann methods for fluid flow through porous media – Part I: Kinetic model derivation

ESAIM: Mathematical Modelling and Numerical Analysis
In this series of studies, we establish homogenized lattice Boltzmann methods (HLBM) for simulating fluid flow through porous media. Our contributions in part I are twofold. First, we assemble the targeted partial differential equation system by formally unifying the governing equations for non-stationary fluid flow in porous media.

Role of non-ideality for the ion transport in porous media: derivation of the macroscopic equations using upscaling

, 2014
This paper is devoted to the homogenization (or upscaling) of a system of partial differential equations describing the non-ideal transport of a N-component electrolyte in a dilute Newtonian solvent through a rigid porous medium.

Multiscale Bone Remodelling with Spatial P Systems [PDF]

, 2010
Many biological phenomena are inherently multiscale, i.e. they are characterized by interactions involving different spatial and temporal scales simultaneously.

Structural Complexity and Phonon Physics in 2D Arsenenes

, 2017
In the quest for stable 2D arsenic phases, four different structures have been recently claimed to be stable. We show that, due to phonon contributions, the relative stability of those structures differs from previous reports and depends crucially on ...

Challenges in imaging and predictive modeling of rhizosphere processes [PDF]

, 2016
Background Plant-soil interaction is central to human food production and ecosystem function. Thus, it is essential to not only understand, but also to develop predictive mathematical models which can be used to assess how climate and soil management ...
