A flow sensing model for mesenchymal stromal cells using morphogen dynamics

Dominique Pioletti, Alexandre Terrier, Miguel Gortchacow

The differentiation of mesenchymal stromal cells has been shown to be af- fected by many parameters such as morphogens, flow rate, medium viscosity, and shear stress when exposed to fluid flow. The mechanism by which these cells sense their environment is ...

Three-dimensional granular model of semi-solid metallic alloys undergoing solidification: Fluid flow and localization of feeding

Michel Rappaz, Jean-Marie Drezet, André Phillion, Meisam Sistaninia

A three-dimensional (3-D) granular model which simulates fluid flow within solidifying alloys with a globular microstructure, such as that found in grain refined Al alloys, is presented. The model geometry within a representative volume element (RVE) consi ...

A multiscale Darcy-Brinkman model for fluid flow in fractured porous media

Alfio Quarteroni, Carlo D'Angelo, Matteo Lesinigo

The aim of this work is to present a reduced mathematical model for describing fluid flow in porous media featuring open channels or fractures. The Darcy's law is assumed in the porous domain while the Stokes-Brinkman equations are considered in the fractu ...

Phase change behavior of ammonia-water mixtures in corrugated plate heat exchangers

Thomas Wicht

The present report describes the work realized in the frame of a Mas- ter Pro ject in collaboration between the company EnBW Energie Baden- Württemberg AG (Germany) and the Section of Mechanical Engineering of the Swiss Institute of Technology of Lausanne ...

In fluid mechanics, turbulence can occur in very simple flow geometries, for Newtonian fluids and without the need for additional flow conditions such as temperature gradients or chemical reactions. In standard cases, intuitive assumptions on the physics o ...

A mesoscale granular model for the mechanical behavior of alloys during solidification

Michel Rappaz, Stéphane Vernède, Jonathan Dantzig

We present a two-dimensional granular model for the mechanical behavior of an ensemble of globular grains during solidification. The grain structure is produced by a Voronoi tessellation based on an array of predefined nuclei. We consider the fluid flow ca ...

Constructal tree-shaped microchannel networks for maximizing the saturated critical heat flux

John Richard Thome, Rémi Revellin

A constructaltree-shaped microchannel network for maximizing the saturated critical heat flux in a disc-shaped planar body has been investigated. n(0) radial channels touch the center and n(p) channels touch the periphery. Designs with no pairing level (n( ...

Poroelastic modelling of peri-implnat gap

Evert Robberecht

Micromotion affects the tissue outcome at the peri-implant site. Interstitial fluid flow, induced by micromotion, may play a curtail part in the mesenchymal stem cell differentiation pathway necessary for bone regeneration. The aim of this project is to mo ...
