Simulation Of Soil Remediation Polluted By Hydrocarbons Using A Non-Thermal Atmospheric Plasma

J. Rojo, S. Ognier, and S. Cavadias
Laboratoire de Génie des Procédés Plasmas et Traitements de Surfaces, University Pierre et Marie Curie, Paris, France

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent ...

Simulation Study of High Frequency Pulsed DC Discharges in Nitrogen

L. Tong [1],
[1] Keisoku Engineering System Co., Ltd., Tokyo, Japan

Pulsed DC technology has led to the design of cost-effective deposition systems and to improved film properties, compared to conventional rf systems. In this work, a two-dimensional finite element model is used to investigate the high frequency pulsed DC discharges in nitrogen. The study ... En savoir plus

Comparison of User vs. COMSOL® Developed Automated Installation Verification of COMSOL Multiphysics® Software

M. W. Crowell [1],
[1] Oak Ridge National Laboratory, Oak Ridge, TN, USA

Verifying that a local software installation performs as the developer intended is a potentially time consuming but necessary step for safety related codes. Automating this process not only saves time, but can increase reliability and scope of verification compared to ‘hand’ comparisons. ... En savoir plus

The Analysis of the Conditions of Flow in the Tundish Performed by a Numerical and Physical Method

T. Merder [1], J. Jowsa [2], A. M. Hutny [2], J. Pieprzyca [1], M. Warzecha [2],
[1] Silesian University of Technology, Katowice, Poland
[2] Czestochowa University of Technology, Czestochowa, Poland

Studies of the liquid metal movement (hydrodynamic) in a real object (tundish) are substantially precluded due to the objective difficulties (high temperature and the size of metallurgical equipment), compared to their execution by the use of physical and numerical modeling. In presented ... En savoir plus

Design and Simulation of MEMS Micro Heater for DNA Amplification

D. Sharma [1], A. Siddiqua [1],
[1] Nitte Meenakshi Institute of Technology, Bengaluru, Karnataka, India

PCR (Polymerase Chain Reaction) is a recent well researched technique which can be employed to obtain an amplified DNA (Deoxyribonucleic Acid). A continuous flow polymerase chain reaction with integrated MEMS based design micro heater for DNA amplification is implemented. Temperature ... En savoir plus

N. Manivannan[1], W. Balachandran[1]
[1]Brunel University, Uxbridge, UK

Design of Microwave Resonance Cavity (MRC) to generate non-thermal plasma to treat NOx and SOx from marine diesel engine is presented in this paper. Microwave frequency of 2.45GHz is used generate the required plasma. A number of wave guides are used to transfer the microwave energy ... En savoir plus

SD Numerical Simulation Technique for Hydrodynamic Flow Gas-Solids Mixing

I. Mantilla[1], S. De Vicente[2]
[1]National University of Engineering, Lima, Perú
[2]Polytechnic University of Madrid, Madrid, Spain

We formulate a new mathematical model of gas-solids mixing hydrodynamic flow [1] in a combustion chamber with a fluid bed system used in the combustion of mineral coal waste. This model in study is called Model Gas-Solids Mixing and it is constructed by averaging the conservation ... En savoir plus

Assessment of COMSOL Capabilities to Analyse the Thermo- Hydrodynamic Behaviour of the MSR Core

A. Cammi[1], V. Di Marcello[1], C. Fiorina[1], and L. Luzzi[1]

[1]Nuclear Engineering Division, Department of Energy, Politecnico di Milano, Milano, Italy

The present work is aimed at evaluating the capabilities of COMSOL Multiphysics® to treat heat transfer in Molten Salt Reactors (MSR). The analyzed situation is represented by the molten salt in turbulent regime flowing through a cylindrical channel surrounded by graphite, with both ... En savoir plus

Prototype Probe Development for Liquid Injection Shutdown System Tube Gap Detection by Remote Field Pulsed Eddy Current Technique

T. V. Shyam[1], B. S. V. G. Sharma[1], J. N. Kayal[1]
[1]Bhabha Atomic Research Centre, Trombay, Mumbai, India

Pressurised Heavy Water Reactors (PHWR) play a prominent role in contributing power for the Nuclear Energy Programme in India. In 540MWe type PHWR reactors, there are horizontally placed Liquid Injection Shutdown System (LISS) tubes for injecting poison into the moderator to clamp down ... En savoir plus

Thermal Hydraulic Study for Heavy Liquid Metal Flows using COMSOL Multiphysics

K. T. Sandeep[1], S. Sahu[1], V. C. Chaudhari[1], R. P. Bhattacharyay[1], E. R. Kumar[1]
[1]Institute for Plasma Research, Gandhinagar, Gujarat, India

Liquid metals are the extensively used as coolants in nuclear reactors.However, the heat transfer mechanism differs significantly in low Prandtl number heavy liquid metals (HLM’s) than those observed in common fluids. It is crucial to have the accurate heat transfer correlation for the ... En savoir plus
