Magneto-structural Analysis of Fusion grade Superconducting Toroidal Field Coils

A. Amardas [1], and S. Dwivedi[2]
[1] Institute for Plasma Research, Gandhinagar, Gujarat, India
[2] COMSOL Multiphysics Pvt. Ltd, Bangalore, Karnataka , India

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. ... Read More

Multi-Scale Modelling of Catalytic Microreactors

B. Hari[1] and C. Theodoropoulos[1]
[1]The University of Manchester, School of Chemical Engineering and Analytical Science, Manchester, UK

Microreactors are important alternative to conventional reactors in chemistry, chemical, pharmaceutical and semiconductor industries due to their operation characteristics such as increased mass and heat transfer, uniform flow, safety, high throughput through array configurations, ... Read More

Numerical Investigation for the Effect of Guide Panel on Heat Transfer from Steel Containment

Priyanshu Goyal[1], I. Thangamani[1], V. Verma[1], V.M. Shanware[1], R. K. Singh[1]
[1]Bhabha Atomic Research Centre, Mumbai, India

In a nuclear reactor, the containment is the last barrier for the release of radioactivity during severe accident conditions. Containment material can be concrete or steel or steel-lined concrete. Steel containments have a high load bearing capacity and a high degree of leak tightness at ... Read More

[1] Atomic Energy Regulatory Board, Mumbai, Maharashtra, India
[2] Bhabha Atomic Research Centre, Mumbai, Maharashtra, India

Carbon Steel pipes are used as feeder pipes in Pressurized Heavy Water Nuclear Reactors for carrying the coolant from the inlet headers to the coolant channel and again from outlet of the coolant channel to the outlet headers and are part of the Primary Heat Transport (PHT) System of ... Read More

Thermo-fluid Dynamics Modelling of Hydrogen Absorption and Desorption in a LaNi_4.8Al_0.2 Hydride Bed

D. Baldissin[1] and D. Lombardo[1]
[1]Compumat S.r.l., Torino, Italy

A two-dimensional mathematical model for the absorption and desorption of H2 in LaNi4.8Al0.2 was developed and experimentally validated. The model is composed of an energy balance, a mass balance and a momentum balance. These differential equations are numerically solved by means of the ... Read More

Numerical Simulations of Methane Aromatization with and without a Ceramic Hydrogen Separation Membrane

Z. Li[1], C. Kjølseth[2], S. Hernandez Morejudo[3], R. Haugsrud[1]
[1]University of Oslo, Department of Chemistry, FERMiO, Oslo, Norway
[2]Protia, Oslo, Norway
[3]University of Oslo, Department of Chemistry, InGAP, Oslo, Norway

Oxygen-free methane aromatization has been attracting growing attention due to a potential means for producing high valuable products such as aromatics and hydrogen. Many studies have been focused on catalysts screening and characterization, and elementary thermodynamic steps of the ... Read More

3D Simulation of an Ethanol Reformer

A. Cifuentes [1], J. Llorca [1], R. Torres [1], S. Rosell [1], J. Grau [1]
[1] Universitat Politècnica de Catalunya, Barcelona, Catalonia, Spain

In order to improve hydrogen production in an ethanol reformer it is needed to understand what happens inside it. Also, a simulated model can simulate different work conditions avoiding the necessity of doing tons of experiments. A 3D computational fluid dynamics simulation study of ... Read More
