The aim of the present work is to explore through the developed numerical model the separation of exosomes from a more complex mixture of particles i.e. red blood cells and white blood cells, through combined acoustofluidics and fluid relocation in a bulk acoustic wave microfluidic ...

Convective transport of macromolecules or micro and nanoparticles in microsystems are usually predicted by solving the Navier Stokes equations for the carrier fluid and a concentration equation for the diffusing species. In the case of isolated particles or complicated geometries with ... En savoir plus

Interest in the production of hydrogen from hydrocarbons has grown significantly recently. In order to achieve high surface to volume ratio with reasonable pressure drop, monolithic reactors are used. The goal of this work is to develop a two-phase (gas & solid) transient catalytic ...

This paper explores the performance of a microfluidic mixer that uses a sinusoidal electric field to accelerate the diffusion process between two Newtonian liquid species in an electrolytic solution. The 2D model was developed using the Microfluidics module in the COMSOL Multiphysics® ... En savoir plus

In recent years, Atomic Force Microscopy (AFM) has played a key role in the characterisation of surface structures and materials at the microscopic level. One of the most important aspects of AFM image analysis is the reliable provision of pore size and cross-linking rate data. AFM uses ... En savoir plus

Angular contact ball bearings (ACBB) are rolling bearings designed to support both axial and radial loads. The rolling elements (balls in this case) significantly decrease the power losses associated with rotating load bearing by replacing sliding with rolling. However, both the specific ...

When a dual probe heat pulse (DPHP) sensor is installed near the soil-atmosphere interface, the basic assumptions of the infinite line heat source (ILS) model and its improvement, the infinite line heat source model with an adiabatic boundary condition (ILS-ABC), might not be satisfied ...

1 Problem Description Most studies for investigating heat and mass transfer phenomena in sorption storage systems use 1D or 2D numerical models. These are inadequate for analyzing processes in more complex geometries used in current prototypes. We present here a 3D model for the ... En savoir plus

When acoustic applications include small geometries, i.e. mm/submillimeter range, so-called thermoviscous effects can greatly affect the pressure response. This paper deals with acoustic topology optimization of such miniature structures with thermoviscous effects taken into account. ... En savoir plus

High temperature variations inside a tent can be a problem for campers’ thermal comfort. To increase user comfort, Decathlon has tents called "Fresh & Black (F&B)". The main improvement of this equipment lies in the textile technology, regulating the temperature inside and ... En savoir plus
