Finite Element Method as an aid to machine design: A Computational Tool
The paper provides an overview of the state of art in computational electromagnetic. There are three major ar eas like Design, optimization and material selection for the electric machines. The computational tool based on finite elements is very useful and powerful field simulation ... En savoir plus
Finite Element Modeling and Simulation of Electromagnetic Forces in Electromagnetic Forming Processes: Case studies using COMSOL Multiphysics
Electromagnetic Forming (EMF) is a promising and relatively new manufacturing technology having significant advantages over conventional forming processes. A primary characteristic of this process is use of noncontact electromagnetic forces to achieve forming and shaping of various ... En savoir plus
Thermo-mechanical Analysis of Steam Generator Bottom Tube Sheet of Steam Generator Test Facility
Steam Generator Test Facility (SGTF) is set up in IGCAR to optimize the design of Steam Generators (SG) for Fast Breeder Reactors. In the SG of SGTF heat exchange takes place from sodium which enters at 525 ºC and leaves at 355 ºC temperature to the water/steam which enters at 235 ºC and ... En savoir plus
Kinetics of the Carbothermal Reduction of Ilmenite: Grain Pellet Model
A novel mechanism for the carbothermal reduction of Ilmenite is proposed and validated with the help of a comprehensive mathematical model. A time-dependent isothermal pellet-grain model is used to simulate the kinetic behaviour of a spherical pellet of ilmenite (FeTiO3) in CO/CO2 ... En savoir plus
Local Electroporation of Single Adherent Cells by Micro-Structured Needle Electrodes
In spite of its low throughput, Patch-Clamp is the established method for intracellular measurements of the transmembrane potential. To address this problem, we have developed new biosensor-chips with micro-structured needle electrodes (MNEs). MNE-penetration of single cells growing on ... En savoir plus
Magneto-structural Analysis of Fusion grade Superconducting Toroidal Field Coils
In this paper, detail magnetostructural analysis of fusion grade superconducting toroidal field coils that are used in ‘tokamaks’ is presented. The stresses that arise due to Lorentz forces in large size superconducting coils that carry high currents are of catastrophic type in nature. ... En savoir plus
Mathematical Modeling of Direct Borohydride Fuel Cells and its Experimental Validation
Direct borohydride fuel cells (DBFCs) use sodium borohydride (NaBH4) as fuel and hydrogen peroxide (H2O2) as an oxidant. A mathematical model encompassing mass balance of ionic species in different regions of the DBFC is developed. Both the oxidation of sodium borohydride and ... En savoir plus
Thermal Analysis of Intermediate Heat Exchanger in a Pool Type Fast Breeder Reactor
Intermediate heat exchanger (IHX) in a pool-type liquid metal cooled fast breeder reactor is an important heat exchanging component as it transfer heat from the radioactive primary sodium in the pool to the non-radioactive secondary sodium. The secondary sodium ultimately heats up water ... En savoir plus
Microwave Coagulation Therapy Using Microwave Antenna
The purpose of this paper is to illustrate the microwave coagulation therapy (MCT) that can be used mainly for the treatment of hepatocellular carcinoma. In this treatment invasive technique are used in which thin microwave coaxial antenna is inserted into the tumor and the microwave ... En savoir plus
Microwave Interstitial Tumor Ablation: New Modality for Treatment of Liver Cancer
Hyperthermia is newly back in the interest of both, clinical and research oncologists, because of its properties to directly produce permanent damages of the treated tumors and to elicit important immunological responses against cancer cells by changing their immunogenicity. Microwave ... En savoir plus
