We present a novel method for concentrating and focusing small analytes by taking advantage of the nonuniform ion distributions produced by thick electric double layers (EDLs) in nanochannels with heterogeneous surface charge. Specifically, we apply a voltage bias to a gate electrode ... En savoir plus

The temperature distributions inside two packs (in-line and staggered) made of large cylindrical lithium iron phosphate cells (of 18 Ah nominal capacity) are analysed in this paper during a 90 A constant discharge current. The analysis of the battery packs temperature distributions is ... En savoir plus

The nanofluid is a class of fluids with high thermal conductivity and non-Newtonian flow behaviors. In this work, we present numerical simulations of spreading characteristics for nanofluids droplet impinging on the solid surface which is of great importance in a number of applications ...

The anode baking process has gained significant attention since the 1980s due to its importance in Aluminium industry. A good anode baking process strives to achieve multiple goals including reduction of NOx from emissions. NOx generation is mainly due to the high-temperature ... En savoir plus

We have developed a piezoelectrically controlled MEMS drug delivery device for on-demand release of defined quantities of drug. A drug-loaded micro reservoir (∅6mm×550µm) is sealed by A membrane placed over the drug reservoir on which the piezoelectric material is deposited. On ... En savoir plus

Heat transfer inside a refrigerated truck is a key phenomenon that governs the temperature inside the truck and the regulation of the cooling system. Up to now, a lot of experimental studies ([Tso et al., 02]) have been carried out to assess the effect of opening the door and to minimize ... En savoir plus

Individual batteries have their own operational temperature ranges, which shall be respected to avoid both damaging of the cells and shortening of the cycle life. In terms of the Li-Ion cells, many of them do not function well at higher temperatures. Therefore, a better understanding of ... En savoir plus

Examples of Electromagnetic processes are presented: (1) cold crucible, (2) electromagnetic pump, (3) DC electromagnetic brake. A combined approach by using multiphysics modeling with Comsol and experimental validation is used in order to give some guidelines for process improvement and ... En savoir plus

The study of low Reynolds number flow around air vehicles of the order of centimeters. According to DARPA, a NAV is defined as a vehicle with 7.5 cm of length and weight of 20 grams. We calculated the flow around a small length scale 3D rigid body with complex geometry. Firstly we ... En savoir plus

In the poster you can see a project where using computational tools like the COMSOL Multiphysics® software, hydrodynamics of a photo electrocatalytic reactor was studied. It was evident that the influential factor is the geometry of inlet and exit header. Therefore, these changes were ... En savoir plus
