In a water based electrolytic polishing process, the formation of molecular hydrogen at the cathode is unavoidable and it can contribute to the formation of surface defects at the anode side. This paper presents the work to model and simulate the molecular hydrogen flow inside radio ... En savoir plus
Nitrogen oxides are one of the more dangerous ingredients contaminating the atmosphere. They are considered to be almost ten times more harmful than carbon monoxide, and sulfur dioxide several times. A whole range of photochemical reactions involving nitrogen oxides are responsible for ... En savoir plus
This project makes a first attempt at modelling fluid flow over shark skin on a microscopic level. The modeled fluid flow shows good agreement with theory. Further refinement of the model parameters holds promises of better understanding of this complex fluid flow phenomenon. The COMSOL ... En savoir plus
Wear in hydrodynamic journal bearings resulting from solid contact in the mixed friction regime becomes an increasingly prominent topic leading to the necessity of numerical wear evaluations. A numerical method tackling this topic based on Archard’s wear law is presented and applied on a ... En savoir plus
Thermoelectric generators (TEG) use Seebeck’s effect to directly convert heat into electricity. TEG represent, therefore, a promising option for energy harvesting of waste heat, for example in car exhaust systems. To investigate the dynamic behavior of high temperature TEG, a test ...

Highly loaded lubricated machine elements such as gears or camshafts are an integral part in a wide variety of technical products. Due to higher efficiency requirements these machine elements have to be improved continuously, which leads to the necessity to investigate physical ... En savoir plus
Pervaporation is the selective evaporation of one component in a liquid mixture using a membrane. HybSi pervaporation membranes consist of porous ceramic support tubes with a thin selective layer on the inside or feed side. Modules for 7 and 19 membrane bundles (surface area up to 2.0 ...

As known, air quality in urban areas is dramatically affected in particular by the noteworthy presence of respirable suspended particulate matter (such as PM2.5), nitrogen oxides (NOx), carbon monoxide (CO) and hydrocarbons (HC), which are mainly due to traffic-induced emissions. On the ... En savoir plus
A wind tunnel experiment was modelled using COMSOL Multiphysics® CFD software. A k-ω coupled turbulence model was considered including the Brinkman equation for stationary air flow through a porous vegetation section. En savoir plus
Aqueous polymers used for enhanced oil recovery (EOR) application is considered a complex fluid. It can exhibit Newtonian and Non-Newtonian behavior depending on the velocity or the stresses that it is submitted during the flooding process. Therefore, the polymer flooding project ... En savoir plus
