Enzyme reactions, blood flow and diffusion in human vasculature play interacting and fundamental roles in blood coagulation. In this complex mechanism, the balance between blood and clot is a delicate equilibrium, whose tight regulation is vital to avoid pathologies such as bleeding and thrombosis. The secondary hemostasis triggered by tissue factor in platelet poor plasma is studied up to ...

Air supply hoses are also predominantly used in the medical industry to aid in patient oxygen intake. In many situations, the outside of the hose can be contaminated with chemicals, especially if the hose lies on the ground in an environment where chemicals are easily found. Permeation and transport of chemicals into the walls of air supply hoses is a noteworthy problem in the chemical ...

In the present work, COMSOL Multiphysics® software was used to solve a mass transfer based mathematical model (Stastova et al., 1996) which is a modified form of Sovova H.,1994 model. The modification has been brought about by introducing the term ‘Grinding efficiency’ in the model and the results of the this model has been compared with the theoretical results obtained by Duba and Fiori, 2015 ...

Immense amounts of methane are stored as gas-hydrate deposits in deep layers of marine sediments. This has raised considerable interest to develop strategies for producing natural gas from marine hydrates. One potential production strategy is the injection of supercritical CO2 into methane hydrate-bearing sand layers to release the CH4 as a gas and sequester the CO2 as hydrate. We used COMSOL ...

This poster studies catalytic micropumps and their ability to induce fluid flow on the microscale. The goal of the study is to design a long-distance, directed convective loop. An array of catalytic micropumps was constructed in the domain, comprised of two distinct catalysts in an alternating pattern with a uniform concentration of their respective reagents in the surrounding geometry. Two ...

This paper describes the modeling of a blood glucose sensor using COMSOL Multiphysics. Chemical species interaction and diffusion, coupled with electrochemical oxidation of multiple blood species produced a powerful working model used in developing and refining a range of blood glucose sensors for the commercial market.

Introduction: Development of next-generation chemical processes that have zero emissions is a key environmental objective for sustainable development. The manufacture of H2SO4 by the air oxidation of SO2 to SO3 is an important technology where an opportunity exists for new catalyst development and process innovation by reducing emissions of unconverted SO2 in process reactor tail gases owing to ...

Silicon carbide (SiC) single crystals are industrially produced by the physical vapor transport technique. Apart from the geometry of the growth setup, there are two main process parameters that can be controlled: temperature and pressure. To support the development of the process, numerical simulation has imposed as the only tool able to describe the process itself, providing a good evaluation ...

Hydrogen storage in a metal hydride bed, uses an intermetallic alloy that can absorb efficiently high amounts of hydrogen by chemical bonding resulting to metal hydrides. This alloy is capable of absorbing and desorbing hydrogen while maintaining its own structure. The heat, mass and momentum transfer in a metal-hydride reactor is mathematically described by energy, mass and momentum balance ...
