Heterogeneous photocatalysis an advanced oxidation process (AOP) which in combination with a catalyst and UV irradiation completely mineralizes organic pollutants from water or gases into harmless compounds such as carbon dioxide (CO2) and water (H2O). Photocatalysis as a process is ... Mehr lesen
Geological repository for highly radioactive waste disposal is a system of engineered and natural barriers. The objective of this system is to contain and isolate waste and protect the environment and humans from ionizing radiation. For the evaluation of performance of engineered ... Mehr lesen
In this study, we attempted to develop a simulation to better understand the kinetic of the dye regeneration process in photoanodes of dye-sensitized solar cells (DSSCs). For that purpose, a numerical model was developed using finite element simulation in COMSOL Multiphysics®. The ... Mehr lesen
The high heat loads intrinsically associated with high-energy, high repetition rate laser systems require sophisticated thermal management analyses to minimise the impact of thermal effects on optical performance. Non-uniform heat deposition in optical elements can lead to the onset of ... Mehr lesen
Re-crystallisation of Ni-Mn-Ga Heusler alloys in a floating zone (FZ) optical furnace is a complex problem that depends not only on the compositions of the master alloy and a seed crystal but on the growth speed and evolution of the molten zone shape during the crystal growth process. We ... Mehr lesen
Convective drying of fruits and vegetables is a widely used preservation method and serves to reduce food waste, to make them available off-season and to reduce weight-related transport costs. However, the high energy consumption and impact of the process set-up and process settings on ... Mehr lesen
To achieve the goals of the Paris Agreement and limit global warming below 2 K compared to pre-industrial level, significant energy savings in all fields of industries will be required. One example of energy intensive processes in industrial fabrication is heat treatment. The applied ... Mehr lesen
A numerical model of laser welding process applied on highly optically reflective and thermally conductive materials such as copper has been developped. The latter considers multiphysical couplings of CFD, heat transfers and phase-field representation to account for topological ... Mehr lesen
High power lasers have a wide range of applications. The goal of this work is to analyze and further optimize a beam expander made of 2 lenses used with a kW class laser. The preliminary lens design is performed using an optical design software but its performance analysis, when used ... Mehr lesen
Inertial focusing of particles in a fluid flow is a physical effect induced by inertial forces already happening at the micro-fluidic scale. COMSOL Multiphysics® has provided an implementation of the drag and lift forces to compute this effect for a constant parallel-wall fluid channel ... Mehr lesen
