D. Kekejian [1], L. Khachatryan [2], M. Barekati-Goudarzi [3], D. Boldor [3],
[1] Department of Physics and Astronomy, Louisiana State University, Baton Rouge, LA, USA
[2] Department of Chemistry, Louisiana State University, Baton Rouge, LA, USA
[3] Department of Biological & Agricultural Engineering, Louisiana State University Agricultural Center, Baton Rouge, LA, USA

The IR CO2 laser powered chemical conversions in the gas phase are intriguing and the researchers’ attention was focused on this transformation a while ago. The method, known as Infrared Laser Powered Homogeneous Pyrolysis, or IR LPHP opened reaction pathways not reached by conventional ... En savoir plus

Modeling a Concentrated Solar Thermal Collector for Methane Dry Reforming

S. Verma [1], N. Hotz [1],
[1] Duke University, Durham, NC, USA

Hydrogen has great potential to be the fuel of the future through utilization in fuel cells, but it is rarely found naturally and must be produced in energy-intensive processes. Steam reforming, the process of heating natural gas and steam in the presence of a catalyst to drive a ... En savoir plus

Impact of the Forces due to CLIQ Discharges on the New HL-LHC Beam Screen

M. Morrone [1], C. Garion [1],
[1] CERN, Geneva, Switzerland

In the framework of the high luminosity large hadron collider (HL-LHC) project, important upgrades will take place by 2024 including the installation of new superconducting magnets in which new beam screens will be placed. The beam screen is an octagonally shaped pipe inserted into the ... En savoir plus

A Transient Unified Model of Arc-Weld Pool Couplings During Pulsed Spot Gas Tungsten Arc Welding

A. Traidia[1], and F. Roger[2]
[1]AREVA NP, Technical Center, Saint Marcel, France
[2]ENSTA Paristech, Paris, France

Using COMSOL Multiphysics, a finite element model is introduced in this paper to describe the couplings between the welding arc and the weld pool dynamic in pulsed gas tungsten arc welding. The cathode, arc-plasma and melting anode regions are taken into account. The unified time ... En savoir plus

Radiation Heat Transfer in Imaging Infrared Spectrometer

A. Jhaveri [1], M. Kushhare [1], A. Bhargav [1],
[1] Indian Institute of Technology Gandhinagar, Gandhinagar, Gujarat, India.

Imaging Infrared Spectrometer (IIRS) is a Hyperspectral optical imaging instrument which measures the spectra of a scene in high resolution within spectral bands covering Near Infrared (NIR) to Mid Infrared (MIR) regions. Radiation entering the spectrometer assembly governs the ... En savoir plus
