A membrane distillation process equipped with mesh-type material spacers has been modeled as a two-dimensional conjugate problem in which a simultaneous numerical solution of the momentum and energy of the feed and cold solutions have been carried out. The results shows that the center suspended spacer produces the highest average shear stress, and gives the highest spacer efficiency at all ...

Finite Element Method simulations of microstructure behaviour is carried out by COMSOL. This enables us to make also technological considerations related to the easy way of fabrication and to lower production costs as explained in the following slide.

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 produce a uniform coating when used with non-Newtonian fluids. With a multiphysics calculation involving the ...
COMSOL Grab Bag: How to Use a Versatile CFD Code to Model Interesting Problems from Cryogenic Storage to Biofuel Production
Senior Research Engineer,

Drilling horizontal wells (HWs) has recently received renewed attentions with the increasing trend in exploitation of tight gas reservoirs. An accurate estimation of productivity of such systems using a numerical simulator is a challenging task, because its 3D simulation requires a fine grid exercise to capture the abrupt variation of fluid and flow parameters around the wellbore. This is ...
Dr. Franck Pigeonneau is currently working in the joint laboratory between the Centre National de la Recherche Scientifique (CNRS) and the company Saint-Gobain. He received his Ph. D. in 1998 from the University Pierre et Marie Curie (Paris, France). His main research activities are devoted to the transport phenomena in high viscous fluids relevant for glass melting processes. He is using COMSOL ...

In this paper we used COMSOL Multiphysics to model basic physico-chemical effects relevant in polymer enhanced oil recovery (EOR) such as non-Newtonian rheology of the displacing phase, permeability reduction, adsorption and salinity effects. COMSOL\'s PDE interface as well as Species Transport in Porous Media interface was used for solving the underlying equations. The validity of the ...

Most of mining works, either on the surface or in the underground, demand continuous groundwater pumping in order to operate under dry conditions. When the mining activity stops, dewatering also stops and mining facilities begin to flood, quite quickly at the beginning but becoming slower as the water level in the pit lake rises. The rise of the surface of the lake decelerates due to the bigger ...

The ability of an industrial mixing tank to homogenize its contents decays rapidly as the Reynolds number is decreased in the transitional regime and approaches the laminar regime. A model of a mixing tank was developed using FEMLAB and using a CFD technique known as momentum source modelling. The model predictions of velocity components agree well with LDA measurements. Decolorization ...
