Vacuum distillation furnaces (VDFs) are employed for purification and consolidation of heavy metals from their dendritic forms which are entrained with molten salts. The VDF is an induction heated furnace which is operated at a temperature of 700-1400 °C and at a pressure of 0.01-600 ... En savoir plus
Magneto-Hydrodynamic (MHD) power generation systems were originally investigated starting from the fact that the interaction of a plasma with a magnetic field must take place at much higher temperatures than could be observed in a mechanical turbine. The main problems of traditional MHD ... En savoir plus
Natural convection has to be accounted and simulated for in order to properly describe the physics encounter in the phase change process. A simplified two-dimensional model was created in COMSOL 4.1. Natural convection was accounted for by adding a volume force and using the Boussinesq ... En savoir plus
The purpose of this study was to develop mathematical models of the coupled electro-thermal process in selected, typical contactors that could then be validated and verified by comparing model predictions with the results of previous studies and with experimental data obtained during a ...

Induction furnaces are employed for vacuum distillation process to recover heavy metals after electro-refining operation. Induction furnace of suitable heating rate and cooled by passive means are required to be developed for this purpose. It is planned to set up a mock up induction ... En savoir plus
Established joining techniques like welding, soldering or brazing typically are characterized by a large amount of heat load of the components. Especially in the case of heat sensitive structures like MEMS this often results in stress induced deformation and degradation or even damaging ... En savoir plus
An axially symmetric multiphysics model for industrial induction furnaces has successfully been converted from COMSOL Multiphysics version 3.5a to version 4.2. The model combines computation of magnetic fields, heat transfer and thermal stresses. The inner part of the furnace is ... En savoir plus
Flows of electrically conducting liquids in external magnetic fields are present in several applications. In this kind of flow, the inhomogeneous magnetic field creates a breaking force on the conducting fluid. As a result, a stagnant zone is formed in the zone affected by the localized ...

In the design of electrorefiner, Working electrode and Counter electrode surface areas are very important. The main aim of this study is to understand the effect of the ratio of Anode to cathode Surface areas in an electrorefining cell. Application of this model to design electrorefiner ... 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
