Modeling Energetic Efficiency of Coil Annealing Using Hydrogen Gas

Abdallah Haouam, Maxence Bigerelle, Bachir Merzoug

Determining the temperature of several steel coils, heated in a furnace traversed by hydrogen, is approached by numerical modeling using differential equations governing heat transfers involved. The resolution is performed by the method of finite differences. Convergence standards of different...

Parametric Study on Thermal Performance of PCM Heat Sink Used for Electronic Cooling

Salma Gharbi, Souad Harmand, Sadok Ben Jabrallah

This work presents a numerical study on the thermal behavior of a PCM heat sink for the purpose of electronic cooling. Introducing copper fins inside a PCM heat sink was examined. A parametric study was performed to maximize the critical time elapsed before reaching the allowable temperature limit...

On the modeling of a visco-hyperelastic polymer gel under blunt ballistic impacts

Anthony Bracq, Grégory Haugou, Benjamin Bourel, Christophe Maréchal, Franck Lauro, Sébastien Roth, Olivier Mauzac

In this paper, the modeling of a polymer gel used as target medium in blunt ballistic experiments is presented. A new visco-hyperelastic law based on the Mooney–Rivlin model is proposed and implemented in a numerical simulation software. The material model identification relies on mechanical...

Separation and preconcentration of actinides from concentrated nitric acid by extraction chromatography in microsystems

Marion Losno, Julien Pellé, Mylène Marie, Ivan Ferrante, René Brennetot, Stéphanie Descroix, Clarisse Mariet

An original method of monolith impregnation in microsystem for the analysis of radionuclides in nitric acid is reported. Three microcolumns made of monolith poly(AMA-co-EDMA) were impregnated in COC microsystems. The robustness of the microsystems in nitric acid media until 8 M was demonstrated....

Study of engine performance, emission and combustion characteristics fueled with diesel-like fuel produced from waste engine oil and waste plastics

V. Edwin Geo, Ankit Sonthalia, Fethi Aloui, J. Femilda Josephin

Utilizing oil extracted from waste engine oil and waste plastics, by pyrolysis, as a fuel for internal combustion engines has been demonstrated to be one of the best available waste management methods. Separate blends of fuel from waste engine oil and waste plastic oil was prepared by mixing with...

Lattice Boltzmann Model for Incompressible Axisymmetric Thermal Flows With Swirl

Insaf Mehrez, Ramla Gheith, Fethi Aloui, Samia Ben Nasrallah

This paper presents a Lattice Boltzmann (LB) model for incompressible axisymmetric thermal flows. The forces and source terms are added into the Lattice Boltzmann Equation (LBE) and the incompressible Navier-Stokes equations are recovered by the Chapman-Enskog expansion. The model of Zhou [1] is...
