The generation 4 of molten salt reactors using the thorium cycle are characterized by a temperature close to 1000 oC. The very large heat transfers involved between the reactor core and the external parts with minimal thermal losses are a major issue. This study investigated a possible inner loop made of a series of conventional graphite filter plate exchangers, pipes and pumps, using the COMSOL ...

This paper investigates the effects of the soft field character of an Electrical Capacitance Tomography system by means of analyzing the 3D sensitivity distribution of the pipe interior using Finite Element Analysis.The aim of the determined sensitivity is to overcome restrictions caused by the soft field without being forced to use (active) guarding strategies.

COMSOL Multiphysics was used to model and simulate the thermal performance of solid targets irradiated with charged particles.Results showed that materials with a high thermal conductivity to heat capacity ratio behave better in cooling dynamic systems requiring fast dissipation of heat.

Eddy Current Non Destructive Testing is exploited to evaluate the structural integrity of metallic objects. The aim of this paper is to detect defects located in depth within the inspected object; within this framework, we studied the modelling of exciting coils useful to detect structural flaws. The simulations have been carried out by considering the movement of the coil over a structural steel ...

In-situ electrical heating technologies are among the most recent technologies used for bitumen recovery from tar sand and oil shale. These technologies have limited environmental impact because there is little disturbance of the land, and water and solvents are not used. Two-phase movement of bitumen and air in tar sand porous deposit is modeled using COMSOL Multiphysics. A system of non-linear ...

Augmented reality is predestined for visualization of electromagnetic fields in air or inside transparent matter. Real existing objects are studied and invisible electromagnetic fields are added as virtual objects. Hence, experts as well as students are able to connect electromagnetic fields easily with studied objects. They can concentrate on physical effects instead on reading figures. Here, an ...

In 1966, mathematician Mark Kac proposed the question "Can One Hear the Shape of a Drum?" in an article for American Mathematical Monthly. In attempting to resolve the Chesapeake Bay from an eigenfunctional approach, a one-to-one mapping of this famous problem has been identified. The quote above will re-write to "Can One Hear the Shape of a Drum from Multiple Point-Sampled Spectra?". This ...
Development of an Interlinked Curriculum Component Module for Microchemical Process Systems Components Using COMSOL Multiphysics

COMSOL Multiphysics provides a powerful numerical platform where various models for microchemical process technology components can be readily created for both education and research. This modeling tool allows chemical engineering students to focus on understanding the effects of various microchemical system component design and operational parameters versus coding and debugging of the numerical ...

Fault Current Limiters (FCLs) are expected to play an important role in the protection of future power systems due to the rising levels of the short-circuit currents. The inductive FCLs, comprising magnetic cores and one or more dc and ac windings, are particularly interesting because they inherently react on the fault. The so-called open-core FCL configuration employs only one magnetic core for ...
Study of a Self Heating Process of Tetrafluoroethylene by the Exothermic Dimerization Reaction to Octafluorocyclobutane

The self heating process of Tetrafluoroethylene caused by an exothermic dimerization reaction was studied. The heat of reaction can lead to a thermal explosion by the decomposition of the Tetrafluoroethylene. Different reaction kinetics, including multistep kinetics, were used to describe the mass balance. The COMSOL Chemical Engineering Module was used to perform the simulation which was ...
