In this article we present Simulations results of an evaporation reactor for optical layer applications. The thermal simulation concern the source of the evaporated material. An experimental problem is ralated to the shape of the material powder surface: due to the evaporation rate, the ... Mehr lesen
We consider the fluid dynamics problem of homogeneously filling a large tank by multiple inlets fed from a piping system. Suitable pipe geometries must be chosen so that the volume flow is constant for all inlets. In this work, we compare both for a piping system as depicted in fig. 1: A ... Mehr lesen
This study deals with the 3D modeling of a light photocatalytic textile. This process aims to decontaminate industrial effluents such as water with pesticides. The present study describes the implementation of a reactive transport model in a computational fluid dynamics model developed ... Mehr lesen
Plasma reactors can be applied to the conversion of waste, biomass and fuels to synthesis gas (mixture of hydrogen and carbon dioxide) with efficiencies as higher as 90-95% and low energy demand, depending on the design optimization. In this work, a multi-step approach was applied to the ... Mehr lesen
In recent years, the optimization of high-temperature superconductors (HTS) has shown promising potential for developing advanced cable layouts aimed at the realization of practical fusion reactors. Despite their excellent performance in terms of electromagnetic and mechanical stability, ... Mehr lesen
Non-thermal plasma, generated in atmospheric pressure discharges, has been investigated in our laboratory in order to treat highly diluted (300 ppm to 1000 ppm) volatile pollutant. The collision of electrons created in the discharge with atmospheric air, leads to the formation of ... Mehr lesen
Climate change is a short-term problem which can no longer be ignored and affects everything, from global food security to geopolitics and economics: extreme weather phenomena, falling crops yields, decrease of water availability, sea level rise, extinction of several animal species, are ...

The annular reactor is a very useful design to carry many chemical reactions. In this study, COMSOL Multiphysics® software was used to study the isothermal mass transfer from the inner side of the outer tube of the annular reactor in the range of 200 Mehr lesen
Engineering design studies of the feasibility of conversion of the High Flux Isotope Reactor (HFIR) from high-enriched uranium to low-enriched uranium fuel are ongoing at ORNL as part of an effort sponsored by the U.S. Global Threat Reduction Initiative program. HFIR is a very high flux, ... Mehr lesen
1 Problem Description Most studies for investigating heat and mass transfer phenomena in sorption storage systems use 1D or 2D numerical models. These are inadequate for analyzing processes in more complex geometries used in current prototypes. We present here a 3D model for the ... Mehr lesen
