Effect of Permeability Diminution in Nutrient Diffusion in Intervertebral Disc
Intervertebral discs (IVD) are fibro-cartilages situated between vertebrae providing their joint flexibility. They play a major role in the transmission and absorption of load through the spine. The disc can undergo progressive structural and quantitative changes in its composition and ... Mehr lesen
Hydrodynamics and Mass Transfer in Taylor Flow
In the present work, numerical simulations of a Monolith Reactor (MR) are carried out in order to develop a pre-design tool for industrial-scale reactors applied to highly exothermal reactions. The reacting circular channels (2-4 mm internal diameter) are coated with a few micron thick ... Mehr lesen
Development of a COMSOL Application for the Efficient Evaluation of an Engineered Barrier System
Radioactive waste repositories include barriers that work to contain the waste, thereby protecting human health and the environment. In deep geological disposal systems, barriers include the natural geological barrier and the engineered barrier system (EBS). The ability of the EBS to ... Mehr lesen
Modeling Degradation in Lithium-Sulfur Batteries
Two Anode Surface processes are examined : Formation of Solid Electrolyte Interphase (SEI) and heating due to Shuttle Current. During charging, higher order sulfur species are reduced at the anode surface, while they are concurrently being oxidized at the cathode. This leads to the ... Mehr lesen
Interface Phenomena for a Multifunctional Air-Water Micro-Particle Collecting and Filtering System
The confinement clean rooms used in industry are susceptible to higher count of particles per cubic meter of air after the usual work program. To decrease the economic and technological effects of particle concentration a micro-cleaning device was elaborated. A first approach of a 3D ... Mehr lesen
Comparison of Industrial Agitation for Batch Reacting Vessel Mixing in Bioethanol Fermentation
This paper presents the investigation into the phenomena during batch reactor vessel mixing comparing agitation equipment; the Rushton turbine and the Marine propeller; in the production of bioethanol by yeast fermentation. The key factors addressed in selecting equipment were fluid ... Mehr lesen
Design of an Anisokinetic Probe for Sampling Radioactive Particles from Ducts of Nuclear Facilities
The aim of this study is to design a new concept of shrouded probe that meets the ISO 2889 requirements and it is suitable for small-ducts installation. In order to reduce the construction costs they have been considered standard stainless steel welding fittings manufactured according to ... Mehr lesen
Non-isothermal Flow of CO2 in Injection Wells: Evaluation of Different Injection Modes
Injection conditions of CO2 at the wellhead may play a major role on the flow behavior through the wellbore. The density and the injection rate reached at the bottomhole are key factors affecting the performance and efficiency of CO2 geological storage. In this work, a model of non ... Mehr lesen
Numerical Modeling of Solvent Enhanced Water Flooding
Mutually soluble-solvents can improve the ultimate recovery in conventional reservoirs. Initially, the solvent moves with the imbibing aqueous phase into the reservoir. However, upon contact with oil, diffusion occurs and the solvent is transported in the oleic phase. Through the ... Mehr lesen
Modeling of Transport Phenomena in Laser Welding of Steels
Laser Welded Blank solutions enable to reduce vehicles weight and to optimize their crash performances by means of simultaneous tuning of different grades and thicknesses. The present work aims to characterize numerically and experimentally materials mixing during laser welding. For ... Mehr lesen
