Gas lubricated bearing has been developed for high accuracy in precision machines and equipments. Gas lubricated bearings are mainly two types: aerostatic bearings, which require a feed of pressurized gas for their operation, and aerodynamic bearings, which generate their own internal ...

Sodium is used as a coolant in Fast Breeder Reactors. Eddy Current Flowmeter (ECFM) is used for measurement of sodium flow in the primary pump and at the outlet of the subassemblies. Eddy Current Flowmeter (ECFM) works on the principle of change in the magnetic field profile due to ... En savoir plus
Permanent Magnet Flowmeter (PMFM) is a non invasive device, which is used to measure the flow of electricallyconducting sodium in Fast Breeder Reactor Circuits. PMFM works on the principle of generation of motional EMF by magnetic forces exerted on the charges in a moving conductor. In ... En savoir plus
In this paper a finite element method(FEM) study of a surface acoustic wave (SAW)device excited by electrostatic coupling method is performed by using COMSOL Multiphysics. We have modeled a Rayleigh wave type SAW device by choosing YZ Lithium niobate as the substrate. The effect of ... En savoir plus
The effects of electric fields on combustion flames have been studied by using several types of experimental techniques as well as few numerical methods. The flame is influenced by the electric field mainly due to the charges present as a result of chemical reactions that take place in ... En savoir plus
The multiphysics simulation package COMSOL was incorporated into a course in mathematical modeling for chemical engineers. Our implementation for the first year of using COMSOL in the course is described, and assessment results based on examinations and student survey results are ... En savoir plus
In-situ electrical heating technologies are among the most recent technologies used for bitumen recovery from tar sand and oil shale. These technologies have limited environmental impact because there is little disturbance of the land, and water and solvents are not used. Two-phase ... En savoir plus
When the dimensions of the material approach is a comparable size to the phonon mean free path, heat flow enters a new regime, the nanoscale. The Fourier and Cattaneo Equations describe bulk heat flow well, but radiative boundary terms must be considered when modeling nanoscale heat ... En savoir plus
Finite elements using COMSOL Multiphysics have been used to simulate the edge plasma in a large area capacitively coupled RF reactor. In order to reduce numerical difficulties simplified reactor edge geometries have been used. First results show the importance of electrostatic double ... En savoir plus
An optimal control problem (OCP) is studied to a PDE of elliptic type as well as state constraints. The resulting optimality system contains two PDEs, one algebraic equation and the so called complementary slackness conditions, i.e. dual products between function spaces. At this point, ...
