Pyrolysis is a key step in the conversion of carbonaceous materials into useful products. In this study, we investigate the pyrolysis of asphaltene and oil shale, both experimentally and numerically. COMSOL Multiphysics® software is used to model the combined effects of fluid flow in porous media, mass transfer of species, heat transfer, and reaction kinetics. Gas evolution and the porosity ...

REBCO tapes belong to a class of high-temperature superconductors (HTS) that can be superconducting at liquid nitrogen temperatures (77K) as opposed to typical superconductors such as Nb3Sn which need to operate at liquid helium temperatures (4K). One important aspect of designing a super conducting coil is the ability to predict the critical current above which the conductor becomes ...

The kinetic interface-sensitive tracers (KIS tracers) are used to give a partial picture of the spreading, mixing and plume migration of supercritical carbon dioxide (scCO2) in the deep saline aquifer by estimating the interfacial areas between scCO2 and brine during the injection of scCO2. To get a better understanding of the KIS tracer reaction and transport processes in the two-phase flow ...

This work aims at the modelling of a 5 cm^2 Direct Methanol Fuel Cell (DMFC) with mixed serial/parallel serpentine flow fields in terms of current/voltage behavior. One of the main challenge to overcome consists on lowering the so-called methanol cross over from the anode through the polymer membrane to the cathode that is responsible for mixed-potential formation at the cathode where both ...

Thermal ablation in the head and neck requires accurate thermal dose delivery to target tissue while protecting the structure and function of nearby tissue and organs. In this study, we present a method that allows importing Computed Tomography (CT) scans to COMSOL, in order to model accurately the expected pathological outcomes prior to thermal ablation treatment. Thermal ablation of a virtual ...

Heat transfer from a sphere having a uniform temperature and falling axially in a cylindrical tube filled with an incompressible power-law liquid is numerically investigated. The governing equations for simultaneous flow around a confined sphere and heat transfer to power-law fluids were solved numerically using COMSOL Multiphysics. It was found that the wall effects on the mean Nusselt number ...

Brain edema is one of the most common consequences of serious traumatic brain injuries which is usually accompanied with increased Intracranial Pressure (ICP) due to water content increment. A three dimensional finite element model of brain edema is used to study intracranial pressure in this paper. Three different boundary conditions at the end of Cerebral Spinal Fluid (CSF) were used to ...

The long-term performance of double U-tube Borehole Heat Exchangers (BHEs) is studied numerically by considering three different time-dependent heat fluxes exchanged between each BHE and the ground. Since the temperature distribution along the vertical direction has a negligible influence on long-term BHE performance, the problem is studied by means of a 2D conduction model, where the energy ...

An undergraduate course is developed to initiate future engineers to multiphysics numerical simulation by approaching concrete cases in various fields such as: heat transfers, fluid flow, mechanics, chemistry and electrostatics. The so called “Virtual Experiments” course consists of four projects given successively to students. Each project lasts about ten hours. The major notions related to ...
