[1] Department of Electrical & Instrumentation Engineering, SLIET , Longowal (Deemed University), Punjab
[2] ABES Engineering College, Department of Electronics and Communication Engineering, Ghaziabad

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 ... Read More

Microwave Interstitial Tumor Ablation: New Modality for Treatment of Liver Cancer

S. Maini[1] , A. Marwaha[1] , and S. Marwaha[1]

[1] Department of Electrical & Instrumentation Engineering, SLIET , Longowal (Deemed University), Punjab

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 ... Read More

Thermal analysis of a spent fuel transportation cask

P. Goyal[1], V. Verma[1], R. K. Singh[1], and A. K. Ghosh[1]
[1]Reactor Safety Division, Bhabha Atomic Research Centre, Trombay, Mumbai, India

Spent fuel transportation casks are required to meet among others (test conditions), the regulatory thermal test conditions in order to demonstrate their ability to withstand specified accidental fire conditions during transport. This paper describes the transient thermal analysis ... Read More

Modeling and Analysis of a Feedback-Controlled Active Magnetic Levitation System using COMSOL Multyphysics Finite Element Software

M. Nabi[1], and K. V. Ajeeth[1]
Department of Electrical Engineering, Indian Institute of Technology Delhi, India

Magnetic levitation systems have been studied in the context of high-speed transportation as maglev trains, high speed machinery as magnetic bearings, and other similar engineering applications. In this paper, a three dimensional arbitrary shaped object is modeled and analyzed through ... Read More

Simulation of AC Loss in High Temperature Superconducting Cable using COMSOL Multiphysics

G. Konar[1], R. K. Mandal[1], A. Chakrabarty[1], J. Das[1], and N. Chakraborty[1]
[1]Power Engineering Department, Jadavpur University, Kolkata, West Bengal, India

In this paper simulation of the alternating current loss (AC loss) in a high temperature superconducting tape and a HTS cable having 4 layers of polygon conductors using COMSOL Multiphysics software has been reported. The simulation results for the single rectangular tape are verified ... Read More

Modeling of Temperature Fluctuations in Frozen Fish

S. Kumar[1], and S. Panigrahi[1]
[1] Agricultural and Food Engineering Department, Indian Institute of Technology Kharagpur, West Bengal, India

The novel concept of distributing the food super chilled (partially frozen) in order to prolong the shelf life has been suggested in the project. The temperature of the distribution chain is envisaged to be +5C. The suggested application has the following advantages: 1) Partial ... Read More

Modelling and Simulation of a Single Particle in Laminar Flow Regime of a Newtonian Liquid

D. Jamnani[1]

[1] Alpha Project Service, Vadodara, Gujarat, India

The interaction of a single particle in straight rectangular channel in laminar flow is modelled explicitly using the set of Navier Stokes equation for the fluid motion and Newton momentum equation for the particle motion in Cartesian coordinate system. The evaluation of integral force ... Read More

Motion of Uncharged Particles in Electroosmotic Flow through a Wavy Cylindrical Channel

N. Qudus[1], T. Mahbub[1], S. A. Ali[1], and M. Shajahan[1]
[1] Bangladesh University of Engineering and Technology, Dhaka Bangladesh

A finite element model is employed to describe the electric potential distribution and electroosmotic flow field inside a wavy cylindrical channel. The model uses coupled Laplace and Poisson-Boltzmann to evaluate the electric potential distribution inside the channel. It also contains ... Read More

Numerical Investigation of Electroosmotic Flow in Convergent Divergent Micronozzle

V. Gnanaraj[1], V. Mohan[1], and B. Vellaikannan[1]
[1]Thiagarajar College of Engineering, Madurai, Tamilnadu, India

A fundamental understanding of the transport phenomena in microfluidic channels is critical for systematic design and precise control of such miniaturized devices towards the integration and automation of Lab-on- a-chip devices. Electroosmotic flow is widely used to transport and mix ... Read More

Optimization of Flow Distribution in the Feed Sparger of a Steam Drum

P. Goyal[1], A. Dutta[1], and A. K. Ghosh[1]
[1] Reactor Safety Division, Bhabha Atomic Research Centre, Trombay, Mumbai, Maharashtra, India

Steam drums of a nuclear power plant separate steam from the steam water mixture and sub cooled incoming feed water returns to the reactor. The entire feed water flow is delivered to the steam drum through the feed water sparger. The feed water sparger is provided with number of ... Read More
