Pseudo-3D Multiphysics Simulation of a Hydride Vapor Phase Epitaxy Reactor

M. Hackert-Oschätzchen[1], M. Penzel[1], P. Plänitz[2], A. Schubert[1][3]
[1]Chemnitz University of Technology, Chemnitz, Germany
[2]GWT-TUD, Dresden, Germany
[3]Fraunhofer Institute for Machine Tools and Forming Technology IWU, Chemnitz, Germany

Gallium nitride (GaN) and its related nitride alloys with special physical properties are in technical areas of high interest. The growing of gallium nitride boules on non-native sapphire or silicon carbide requires complicated mechanisms of defect reduction in the lattice structure. ... Read More

Research and Development of Multiphysics Models in Support of the Conversion of the High Flux Isotope Reactor to Low Enriched Uranium Fuel

The findings presented in this report are results of a five-year effort led by the Research Reactors Division (RRD) of the Oak Ridge National Laboratory (ORNL), which is focused on research and development toward the conversion of the High Flux Isotope Reactor (HFIR) fuel from high ... Read More

Modeling and Simulation of Dielectric Barrier Discharge Plasma Reactor for Nitrogen Fixation Reaction

B.S. Patil[1], Q. Wang[2], V. Hessel[2], J. Lang[3]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands
[2]Micro Flow Chemistry and Process Technology, Eindhoven University of Technology, Eindhoven, The Netherlands
[3]Innovation Management, Verfahrenstechnik & Engineering, Evonik Industries AG, Hanau-Wolfgang, Germany

Fixed nitrogen is used in many forms ranging from nitric acid to hydrogen cyanide and is used as such for industrial applications. The reactions to produce these products are highly endothermic and favored by high-temperature processing. The most basic route of chemically fixing nitrogen ... Read More

Modeling of a Biogas Steam Reforming Reactor for Solid Oxide Fuel Cell Systems

F. Cipitì[1]
[1]CNR-ITAE, Institute of Advanced Technologies for Energy, Messina, Italy

A biogas steam reforming reactor has been developed in order to be integrated into a proof-of-concept SOFC system, able to operate with biogas produced in an industrial waste water treatment unit. A mathematical model, aimed at describing the performance of the reactor, has been ... Read More

Iberian COMSOL Multiphysics Conference 2024

In this conference we have brought together a community that is scientifically diverse in an event that allows for inspiring contacts about the use of COMSOL Multiphysics. It is an event to connect with the Spanish and Portuguese COMSOL Multiphysics users and participate in training ... Read More

Modeling of the Reduction Stage during the Continuous Refining of Copper in a Packed Bed Reactor

F. Mansilla[1], L. Voisin [2]
[1]Advanced Mining Technology Center, Chile University, Santiago, Chile
[2]Department of Mining Engineering, Advanced Mining Technology Center, Chile University, Santiago, Chile

Throughout history, the copper pyrometallurgical processes have been carried out mostly in discontinuous or batch systems. In recent decades new continuous technologies have been developed but focused only on Smelting and Converting stages leaving aside the Refining one. In 2002 a novel ... Read More

Cluster Diameter Determination of Gas-solid Dispersed Particles in a Fluidized Bed Reactor

M. Das
Department of Biotechnology, PESIT, Bangalore, Karnataka, India

Clustering is a common hydrodynamic characteristic observed among suspended gas-solid particles in a fast fluidized bed (FFB) regime of a circulating fluidized bed (CFB) system. In this paper clustering behavior has been studied with Geldart group B particles like coal and iron ore in a ... Read More

CFD Analysis of Loss Of Vacuum Accident for Safety Application in Experimental Fusion Reactor Facility

C. Bellecci[1], P. Gaudio[1], I. Lupelli[1], A. Malizia[1], M.T. Porfiri[2], R. Quaranta[1], and M. Richetta[1]

[1]EURATOM, Faculty of Engineering, University of Rome “Tor Vergata”, Roma, Italy
[2]ENEA Nuclear Fusion Tecnologies, Frascati, Roma, Italy

In an experimental nuclear fusion facility dust is generated both during normal machine operations and by macroscopic erosion of the plasma facing materials due to intense thermal loads. This dust can be mobilized by air ingress in case of LOVA (Loss of Vacuum Accident) threaten safety ... Read More

Non-uniform magnetic field-induced performance alteration of a topology-optimized PBMR

Debdeep Bhattacharjee¹, Arnab Atta¹, Suman Chakraborty²
¹Department of Chemical Engineering, Indian Institute of Technology Kharagpur, Kharagpur, West Bengal, India
²Department of Mechanical Engineering, Indian Institute of Technology Kharagpur, Kharagpur, West Bengal, India

Packed bed microreactors (PBMR) and ferrofluids are independently enormously used in a broad range of applications in the healthcare sector. In a PBMR, one of the primary factors for controlling the reaction rate is the bed porosity which immediately affects the catalyst distribution and ... Read More

A Preliminary Approach to the Neutronics of the Molten Salt Reactor by Means of COMSOL Multiphysics^®

V. Memoli[1], A. Cammi[1], V. Di Marcello[1], and L. Luzzi[1]
[1]Nuclear Engineering Division, Department of Energy, Politecnico di Milano, Milano, Italy

The Molten Salt Reactor (MSR), proposed along with other five innovative concepts of fission nuclear reactor by the Generation IV International Forum (GIF-IV), represents a challenging task from the modeling perspective because of the strong coupling between neutronics and thermo ... Read More
