Slot coating is a widely used commercial process for applying one or more thin layers to a substrate such as paper, fabric, film or other material. In many cases, a highly uniform thickness is required, where a coating head that has been corrected for use with a Newtonian fluid may not ... En savoir plus

This work demonstrated the importance and feasibility of experimental image to simulation workflow. The workflow is successfully applied to a food processing study, where multiphysics and multiscale modeling based on 3D experimental image reconstruction contributes to the preservation of ...

In biotechnology and medicine, cells are frequently grown on scaffolds with a three-dimensional channel structure. The oxygen and nutrient supply of the cells is realized by a medium flowing through the channels of the scaffolds. However, it is often difficult to obtain a confluent ... En savoir plus

The ongoing trend towards miniaturization, higher integration as well as cost efficiency will make it necessary to investigate a new assembly method for micro components. In this paper, a novel method of fluidic-based micro assembly is presented. A self-assembly effect which is caused by ... En savoir plus

We present a study of an optofluidic biosensor. The sensor operates in a transmission mode wherein detection is based on a shift in the transmission spectrum caused by the contrast in refractive index between the carrier fluid and the target biomaterial. We study the behavior of the ... En savoir plus

The flow morphology of two immiscible fluids in a microfluidic device finds numerous applications such as emulsification, synthesis of nanomaterials [1], lab-on-a-chip devices and biological analysis [2]. It offers many advantages over the conventional macroscopic devices because of its ... En savoir plus

Parametric and topology optimization approaches are widely used techniques for performance improvement of components in terms of various objectives. Especially topology optimization often leads to complex geometries that are difficult or impossible to produce by conventional ... En savoir plus

The present work introduces a new methodology, based on COMSOL Multiphysics® Application Builder, to account for the “beam trapping” effect in multiphysical modelling of laser welding. Incident intensities involved in laser welding processes are high enough to induce material ... En savoir plus

Porous media fluid dynamic modeling has been widely explored and utilized in many academic and industrial applications. Cross flow filtration being one attractive application, whereas the fluid and filtrate flow parallel the porous media, and thereby induce shearing stress along the ... 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 ...
