Calibration of MHD Flow Meter using COMSOL Multiphysics

S. Sahu[1], R. P .Bhattachryay[1], E. R. Kumar[1]
[1]Institute for Plasma Research, Bhat, Gandhinagar, Gujarat, India.

There is limited option for non-intrusive flow measurement of liquid metals at high temperature. Liquid metal flowing in a conduit along with the transverse magnetic field induces emf in the liquid metal. The emf developed; which has linear dependency on flow velocity; can be used for ...

A Study on the Suitability of Indium Nitride for THz Plasmonics

A. Shetty[1], K. J. Vinoy[1], S. B. Krupanidhi[2]
[1]Electrical Communication Engineering, Indian Institute of Science, Bangalore, India
[2]Materials Research Centre, Indian Institute of Science, Bangalore, India

As interest in the electromagnetic spectrum expands towards the infrared and terahertz range, the distinct advantages of using semiconductors instead of metals for plasmonic applications must be understood. Plasmonic resonances in gold (Au) and indium nitride (InN) gratings are studied, ... Read More

Thermal Analysis of Induction Furnace

A. A. Bhat[1], S. Agarwal [1], D. Sujish[1], B. Muralidharan[1], B. P. Reddy[1], G. Padmakumar[1], K. K. Rajan[1]
[1]Indira Gandhi Center for Atomic Research, Kalpakkam, Tamilnadu, India

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 ... Read More

Simulation of Flux Density in a Hybrid Coil SMES using COMSOL Multiphysics

S. Roy[1], G. Konar[1]
[1]Power Engineering Department, Jadavpur University, Kolkata, West Bengal, India

Energy storage is an essential component for hybrid power system using non-conventional energy resources. Batteries, compressed air energy storage, pumped hydro plants etc. have been developed for storage. However, these have demerits like losses involved in energy conversion and time ... Read More

Simulation of Magnetic Flux Distribution of Stator and Rotor Coil of Superconducting Air Cored Wind Turbine Generator using COMSOL Multiphysics

A. Hazra[1], G. Konar[1]
[1]Power Engineering Department, Jadavpur University, Kolkata, West Bengal, India

Wind energy is one of the fastest growing renewable energy sources for electricity generation over the past decade. The offshore installation of large-scale wind farms draws huge attention because of better wind profile. Direct drive synchronous wind turbine generators are now a global ... Read More
