Liquid metals are the extensively used as coolants in nuclear reactors.However, the heat transfer mechanism differs significantly in low Prandtl number heavy liquid metals (HLM’s) than those observed in common fluids. It is crucial to have the accurate heat transfer correlation for the ... En savoir plus
Chemical reactions conducted under microwave irradiation have high reaction rates and high selectivity, but these reaction rates are not always reproducible. To achieve reproducibility, a solid-state microwave source with an ultra precise oscillator, high power amplifier module (HPA), ... En savoir plus
Self-propagating High-temperature Synthesis (SHS), a very economical synthesis of oxides was used in our lab to produce oxide materials. SHS process uses a highly exothermic reaction to convert reactants rapidly to pure products with minimal external energy input. This reaction is ... En savoir plus
An inactive Demonstration facility for the integrated pyroprocess, named High temperature Electrorefining (HTER) facility is in developing stage. This facility is equipped with several types of pyroprocess equipment such as electro-refiner, salt and cadmium distillation equipment, ... En savoir plus
Reformer and catalytic burners are common components in fuel cell systems, crucial for efficient preparation of fuel and exhaust gases of the fuel cell stack. We intend to show the influence of radiation to the temperature distribution inside of a reformer unit. The model consists of an ... En savoir plus
Ultrasound is a promising green technology for the advanced oxidation process (AOP) since it adds no chemicals to the treated water. In this paper, COMSOL Multiphysics® was used as a tool to design and characterize an ultrasound irradiator with multi-stepped configuration, which aims to ... En savoir plus
Ozone treatment is an oxidative process used in wastewater treatment plant to demolish complex organic molecule. In the case of textile industry is required to adequately remove residual color, demolishing the chromophoric bonds or groups in the dye molecules. A useful method for adding ... En savoir plus
The hydraulic flocculates are employed in water treatment plants (WTPs), but may present problems during the mixing stage reducing the efficiency of treatment. In this context modeling of a hydraulic flocculate using COMSOL and a 1:10 scale model of the Maringá-PR Brazil city WTP ... En savoir plus
The plasma enhanced chemical vapor deposition process with a linear plasma source and the frequency range up to 140 MHz developed by Dresden University of Technology and FAP GmbH Dresden enables a fabrication of thin film silicon layers at very high deposition rates. However, an increase ... En savoir plus
Ar/H2 discharges are frequently used in various industrial applications, such as etching processes, surface treatment, and film deposition. In the discharges, the active species, such as ions and hydrogen atoms, are responsible for surface reactions, which could be considered as the ... En savoir plus
