The High Flux Isotope Reactor at the Oak Ridge National Lab is in the research stage of converting its fuel from high-enriched uranium to low-enriched uranium. One of the areas being explored is the fluid-structure interaction phenomenon due to the interaction of thin fuel plates (50 ... En savoir plus

Nuclear fusion represents a promising solution for providing clean and sustainable energy. However, to support fusion reactions, tritium, a rare isotope, must be continuously produced within the reactor. Breeding blankets, which surround the plasma, produce this tritium. These components ... En savoir plus

This study focuses on optimizing the lengths of various structural components around a cylinder to minimize drag. Using COMSOL Multiphysics, numerical simulations involving Laminar Flow were performed. Key components optimized include an arrowhead positioned upstream and two flaps ... En savoir plus

The transfer molding process is a widely used method for encapsulating microelectronics and power semiconductor devices. In power electronics, it is gaining increasing importance, particularly in the automotive sector [1]. In transfer molding, an epoxy mold compound (EMC) is injected ... En savoir plus

Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient leads to a strong electrothermal flow that can be used for multiple purposes. Combining simulations and ... En savoir plus

The WaveEL buoy developed by the company Waves4power is characterized as a point absorber and has a 36 meters long vertical cylinder where a water-piston is oscillating due to induced motion from the waves. Estimating the wave loads on the piston is a challenge due to the presence of ... En savoir plus

This study focuses on the design and optimization of a logging while drilling (LWD) tool with look-ahead detection capabilities, which is widely used in measuring formation resistivity and detecting formation boundaries ahead of the drill bit during oil and gas drilling operations. The ... En savoir plus

A pneumonectomy is an invasive, high-risk surgical procedure performed to remove the right or left lung. Although this may be a life saving procedure for some patients, it has high morbidity rates and many complications post-pneumonectomy. Pneumonectomies result in the heart’s entire ... En savoir plus

Metal foams are interesting materials with many potential uses. They are characterized by a cellular structure represented by a metal (or a metal alloy) and gas voids inside. A common metallic cellular material is a solid sponge, also known as open-cell metal foam. Due to their intrinsic ... En savoir plus

We present a problem-adapted finite element model, which enables the design of a novel type of a highly miniaturized, electrostatic MEMS membrane pump, as well as the investigation and the optimization of its operation. The electro-mechanical actuation scheme constitutes a strongly ... En savoir plus
