A model for CO2 storage is presented. It is shown that the system is highly dynamic, i.e. results depend strongly on parameter disturbances and numerical features. However, a series of scenario calculations shows that there are invariants, most important: the duration of the early convection phase with high mass transfer rates.

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 ...

Eccentricity in annular channels contributes to changes in fluid flow characteristics which in turn, affects the performance and integrity of the configuration. This research investigates a model of an annular channel with a diameter ratio of 0.762, an aspect ratio of 68.9:1 and heating of the internal surface of the inner cylinder with a 1.105MW/m2 heat flux. The Reynolds number ranges from 5 ...
Application of Kelvin's Inversion Theorem to the Solution of Laplace's Equation Over a Domain That Includes the Unbounded Exterior of a Sphere
Florida Institute of Technology, Melbourne, FL, USA
In simulating physical systems modeled as solutions of partial differential equations over an unbounded domain, a challenge arises owing to the impossibility to cover an unbounded domain with a mesh. A classical problem in fluid dynamics, a solid sphere of radius a_s is submerged in a tank of water (at rest) of much larger size. The water is disturbed by the sphere’s sudden acceleration in the z ...

Engineering design studies of the feasibility of conversion of the High Flux Isotope Reactor (HFIR) from high-enriched uranium to low-enriched uranium fuel are ongoing at ORNL as part of an effort sponsored by the U.S. Global Threat Reduction Initiative program. HFIR is a very high flux, pressurized light-water-cooled and moderated, flux-trap type research reactor whose current missions are to ...

Vortex ring can be useful to generate thrust force for e.g., jellyfish, but its mechanism has not been clarified. In this field, it seems that numerical simulation has an important role of understanding the propulsion mechanism of creature. A vortex ring in a tube, refered to confined vortex ring, have been far less studied compared with unconfined vortex rings, despite their importance for many ...

Introduction: Power electronic converters such as those for High Energy Physics Experiments (HEPEs) must operate in thermally hostile environment. Heat generated by electronics components must be conveniently dissipated to ensure electrical performances and improve reliability. Due to the high power density, the presence of closed environments, and the requirement of non-thermal interaction with ...
