Thermoelectric generators (TEG) use Seebeck’s effect to directly convert heat into electricity. TEG represent, therefore, a promising option for energy harvesting of waste heat, for example in car exhaust systems. To investigate the dynamic behavior of high temperature TEG, a test facility was numerically designed and finally constructed. Transient thermal simulations were performed in order to ...
COMSOL Multiphysics® Software: Simplifying Workflow and Promoting Innovations in Nuclear Engineering at ORNL

 Oak Ridge National Laboratory, Oak Ridge, TN, USA
At Oak Ridge National Laboratory (ORNL), COMSOL Multiphysics® software has become a preferred software for certain multiphysics applications in nuclear engineering. This presentation will highlight some of the ongoing activities in the following areas: (1) Highly enriched uranium (HEU) to low enriched uranium (LEU) conversion of the High Flux Isotope Reactor (HFIR), (2) New and improved safety ...

INTRODUCTION Enhancement of a single-photon emission is a great demand in recent science and applications, including development novel class of light sources, encoded information transfer and biological imaging [1, 2, 3]. Fluorescence can be improved through excitation and emission enhancement. Improvement of these two processes can be realized by using the near-field enhancement accompanying ...
Influence of Non-Newtonian Blood Viscosity on Wall Pressure in Right Coronary Arteries with Serial Stenoses

 Monmouth University, West Long Branch, NJ, USA
Three dimensional mathematical models are developed to simulate the blood flows in patient specific right coronary arteries with two stenoses. Simulations are carried out with various flow parameters under physiological conditions. Both Newtonian and non-Newtonian blood viscosity models are applied in the simulations to examine the influence of non-Newtonian viscosity of blood on the wall ...

Methane detection and quantification is of great importance due to its natural abundance, potential to cause explosions and known greenhouse effect. Leak detection and concentration monitoring at source is highly challenging as CH4 is odorless and colorless. This can be performed mounting sensor network over a potential diffusion area. It requires optimal positioning of those sensor nodes to ...

Humanity is faced with an imminent energy crisis. The exponential growth of the human population and the consequential increase of the required energy on a global scale, the dramatic climate change and the exhaustibility of natural resources combined, force us to strive towards a sustainable future. The majority of energy is being produced by fossil fuels, carriers of high density of primary ...

Encapsulation is an established technique to protect sensitive materials from environmental factors such as oxygen and light. Nutritionally beneficial fatty acids like omega 3 fatty acids are susceptible to oxidation and are therefore encapsulated by drying an oil in water emulsion. It is assumed that the wall matrix, that is surrounding the lipid droplets, acts as an oxygen diffusion barrier. ...

Laser-induced forward transfer (LIFT) is a non-contact direct-write technique that enables the deposition of small volumes of material into user-defined high-resolution patterns with a wide range of structural and functional materials. There are many variations of the LIFT process, each differing in how the laser is absorbed and converted into the mechanical energy required for material ejection ...

Excilamps are artificial Ultraviolet sources based on the emission of excimers or exciplexes. The latter are excited states of weakly bound rare gas or halide/rare gas atoms which emit a photon in the UV region when they dissociate. Dielectric Barrier Discharge (DBD) excilamps are promising UV sources for the future, provided the coupling between their power supply is optimized. The model ...

The present work focuses on modeling a new experimental technique: Scanning Electro-chemical Potential Microscopy (SECPM), which is used to probe the potential profile of the electric double layer (EDL). We used an electrostatic approach to compute the EDL potential measured within the metallic probe. Also, we investigated the effect of the interaction of the electrode/probe double layers on the ...
