Investigating the Impacts of Hydrogeological Parameters on DSI Efficiency through Numerical Simulation

Y. Jin[1], E. Holzbecher[1], S. Ebneth[2]
[1]Department of Applied Geology, GZG, Georg-August- University of Göttingen, Göttingen, Germany
[2]Hölscher Wasserbau, Haren, Germany

Düsensauginfiltration (DSI),‘nozzle-suction-infiltration’, is a new method for dewatering that avoids groundwater abstraction from the aquifer. Drawdown is achieved via pumping of groundwater at upper abstraction section, meanwhile, all the pumped water is injected through the same ... Read More

Improvements on Liquid Cyclotron Target Loading/Unloading System Using COMSOL Multiphysics®

F. Alrumayan[1], A. Alghaith[1], J. Schneider, [1], M. Ahmed [1], M. Al-Qahtani[1]
[1]King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia

A 3D model was developed using COMSOL Multiphysics® to study the flow dynamics of the water inside the geometry of the [13N] Ammonia target for medical application . The image attached shows a 3D model of the target. A significant improvement was noted after modifying the geometry as ... Read More

Effects of Flow and Diffusion on Blood Coagulation in Platelet Poor Plasma: a Two-way Coupling Between Hemodynamics and Biochemistry

D. Magnabosco[1,2], H. van Ooijen[2], B. Bakker[2], R. van den Ham[2]
[1]Politecnico di Milano, Milan, Italy
[2]Philips Research, Eindhoven, The Netherlands

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 ... Read More

CO2 Storage Trapping Mechanisms Quantification

A. Nardi[1], E. Abarca[1], F. Grandia[1], J. Molinero[1]
[1]Amphos 21, Barcelona, Spain

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. In general, four ... Read More

A COMSOL Multiphysics®-based Model for Simulation of Methane-Hydrate Dissociation by Injection of Superheated Carbon Dioxide

M. Gharasoo[1], C. Deusner[1], N. Bigalke[1], M. Haeckel[1]
[1]Department of Marine Geosystems, GEOMAR - Helmholtz Centre for Ocean Research, Kiel, Germany

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 ... Read More

In Silico Evaluation of Local Hemodynamics Following Vena Cava Filter Deployment

J. Ferdous[1], M. Ghaly [2], V. B. Kolachalama [3], T. Shazly[1,4]
[1]Biomedical Engineering Program, University of South Carolina, Columbia, SC, USA
[2]Department of Biomedical Engineering, North Carolina State University, Raleigh, NC, USA
[3]Charles Stark Draper Laboratory, Cambridge, MA, USA
[4]Department of Mechanical Engineering, University of South Carolina, Columbia, SC, USA

Inferior vena cava (IVC) filters have become essential components in deep vein thrombosis treatment to prevent preventing pulmonary embolisms. Filter efficacy relies on maintaining IVC patency by preventing filter-induced thrombosis following clot capture. A computational model has been ... Read More

An MHD Study of the Behavior of an Electrolyte Solution Using 3D Numerical Simulation

L. P. Aoki[1], H. E. Schulz[1], M. G. Maunsell[1]
[1]University of São Paulo, São Carlos, SP, Brazil

This article considers a closed water circuit with square cross section filled with an electrolyte fluid. The conductor fluid was moved using an electromagnetic pump, in which a permanent magnet generates a magnetic field and electrodes generate the electric field in the flow. Thus, the ... Read More
