The capture and storage of CO2 in deep geological formations is one of the proposed solutions to reduce CO2 emissions to the atmosphere. CO2 is injected as a supercritical fluid deep below a confining geological formation that prevents its return to the atmosphere. A configuration of denser CO2-enriched brine overlying lighter water leads to convective flow and the formation of gravity fingers ...

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 ...

In a water based electrolytic polishing process, the formation of molecular hydrogen at the cathode is unavoidable and it can contribute to the formation of surface defects at the anode side. This paper presents the work to model and simulate the molecular hydrogen flow inside radio frequency cavity geometries and compares it with the presence, type and relative position of certain defects in ...

In the context of increasing demographic pressures around the world, soil improvement techniques constitute viable alternatives to expensive foundations. Among these techniques, the biocalcification of granular soils appears as a promising alternative relying on the formation of calcium carbonates. The process is relatively basic and energy efficient, as based on the metabolic activity of the ...

This publication aims to investigate conjugate heat and mass transfer around a clothed virtual manikin. This research can be performed at different scales: (1) at material scale where a piece of textile is investigated in 1D or 2D space or (2) at system level where a clothed cylindrical body (2D) or a complete manikin (3D) is modeled. The work is based on previous methods and results from ...

During the pyrolysis and combustion of polymers, heat is released and is typically measured with a cone calorimeter to better assess the polymer’s flammability. Modeling heat release rate, as assessed by cone calorimetry, has not been extensively studied for char-forming polymers, such as, polycarbonate. Here we determine the heat release rate with the help of a one-dimensional transient finite ...

The plasmas generated in water involve various physical phenomena such as flows agitated by bubbles, high electric fields for breakdown, discharges in bubbles with size variation, and so on. In this paper, studies have been made on the simulation of plasmas generated in bubbles with size variation. The species taken in account include electrons, three kinds of ions, and ten kinds of neutral ...

A microfluidic component was designed to collect blood from a finger prick by capillary flow and to perform biological analysis. It was used to perform ABO blood typing experiments in one step, the blood drop deposit, by agglutination of red blood cells (RBC) using embedded dried reagents. The present study is a first step in the modeling of the whole agglutination assay. Blood typing ...

Interest in the production of hydrogen from hydrocarbons has grown significantly recently. In order to achieve high surface to volume ratio with reasonable pressure drop, monolithic reactors are used. The goal of this work is to develop a two-phase (gas & solid) transient catalytic combustor model using a simplified flow field inside a single channel to test the advantages of the COMSOL ...
