We use finite elements simulations in order to study the fluid flow behavior in a chamber of a preconcentrator. We realized that most part of the fluid does not affect our preconcentrator because it is going out the chamber at high distance above it and parallel to the preconcentrator. So, we are wasting most part of our fluid and we need a lot of time to have a good concentrator factor. We ...

This work describes the study of a thermal actuator and modifications to the materials employed in order to decrease power consumption and implementation costs. For this study, we worked on improving the thermal actuator described in the work of T. Ebefors. The criteria for choosing the new materials were lower power consumption, commercial availability, and ease processing. The thermal actuator ...

Computational models of biological systems are becoming more and more common in medical research areas. Evidence of this can be found by examining the number of articles containing the term “finite element” in the expansive National Institutes of Health (NIH) digital research archive PubMed. Numerical modeling of biological systems allows the execution of “computational ...

Magnetorheological Elastomers (MREs) are a composite that consist of magnetic micrometer sized particles suspended within rubber matrix filler. By placing this material within an external magnetic field during the rubber curing process, the poles of the particles are forced to align and form chains of particles within the matrix. These chains cause the MRE to change its stiffness properties when ...

Enzymatic biofuel cells (EBFCs) are miniature implantable power sources, which use enzymes as catalysts to perform redox reaction with biological fuels such as glucose. In this study, we focused on a three dimensional EBFC chip with highly dense micro-electrode arrays, fabricated by carbon-micro-electro-mechanical-system (C-MEMS) techniques. Glucose oxidase (GOx) is immobilized on anodes for the ...

Flow, concentration and temperature fields are studied with numerical and experimental methods inside a scaled-up fuel cell anode channel model. The low aspect ratio channel has a porous medium as the inferior wall where a mixing of different pH solutions occurs. Chromatic change of phenolphthalein is used to visualize concentration field and Particle Image Velocimetry (PIV) is used to visualize ...

In-situ electrical heating technologies are among the most recent technologies used for bitumen recovery from tar sand and oil shale. These technologies have limited environmental impact because there is little disturbance of the land, and water and solvents are not used. Two-phase movement of bitumen and air in tar sand porous deposit is modeled using COMSOL Multiphysics. A system of non-linear ...

The Eustachian Tube (ET) is a collapsible tube that connects the middle ear to the nasopharynx. Dysfunction in the ET leads to a disease called Otitis Media. Our goal is to develop and use fluid-structure interaction (FSI) models of ET opening phenomena to better understand what factors contribute to ET dysfunction in certain patients. We model the ET in COMSOL using geometric data obtained ...

Steam drum in a nuclear power plant is one of the important components of Primary Heat Transport (PHT) system where steam is separated from the steam water mixture. Steam water mixture emanating from the reactor core is separated in a steam drum. Separated steam goes to the turbine whereas separated water after mixing with incoming feed water returns to the reactor. The entire feed water flow is ...
