Heat Transfer in an Oscillating Meniscus
Experimental data for oscillations occurring at the three phase contact line of an evaporating HFE 7000 meniscus on a silica substrate is presented. The frequency of the oscillations were found to depend on the local value of the evaporative heat ?ux. The thickness, slope, and curvature ... 詳細を見る
Constructing COMSOL Models of a Bacteriological Fuel Cell
We have started constructing preliminary design COMSOL models of a bacteriologically driven \'fuel cell\' that is intended to process waste products, such as carbon dioxide and brine, from a crewed vehicle. At this early stage, this complex system is reduced to two electrodes separated ... 詳細を見る
Energetics of Half-Quantum Vortices
Magnetic cantilever measurements have detected half-flux states in mesoscopic rings of the layered material Sr2RuO4, adding evidence that superconducting Sr2RuO4 may be described by a p-wave order parameter. A proposal accounting for this behavior has been presented in which the ... 詳細を見る
Modeling the Chemical Decomposition of Sodium Carbonate Peroxyhydrate
The challenge with the use of Sodium Carbonate Peroxyhydrate (Na2CO3*1.5H2O2) as a bleach source in dry detergent formulations is its lower stability in comparison with other materials, and the risk of quality losses of the product over the shelf life. The issue can be solved with the ... 詳細を見る
Humidity Mass Transfer Analysis in Packed Powder Detergents
Powder detergents containing sodium percarbonate and bleach activators undergo chemical decomposition when exposed to high relative humidity. Controlling the moisture intake in finished product packs is therefore a fundamental need in order to guarantee product stability during the whole ... 詳細を見る
Thermo-Mechanical Analysis of Composite Material Exposed to Fire
This paper presents thermo-mechanical models for predicting the strength of polymer laminates loaded in tension or compression exposed to one-sided radiant heating by fire. The first part is the fire simulation where the FDS model is utilized. The FDS model generates a solution of ... 詳細を見る
Thermal Analysis of a Piezo-Disk Ultrasound Probe
Ultrasound imaging probes are widely used for several types of diagnosis applications. In the present work we focus our attention on a disk-type probe, which is widely used in CW and PW operating conditions. In particular we present a 2D-axial symmetry FEM for the probe, capable to ... 詳細を見る
Downscale Finite Element Modeling of Aortic Valve Leaflets for In-Situ Estimation of Cell Level Mechanics
As in all tissues, mechanical forces in the aortic valve (AV) modulate the constituent cell population’s physiology and biosynthetic activity. While advances have been made toward the understanding of this complex multi-scale relationship, the specific role that and extracellular matrix ... 詳細を見る
A Study of the Effects of Mounting Supports, and Dissipation on a Piezoelectric Quartz Double-Ended Tuning Fork Gyroscope
A COMSOL model of a piezoelectric quartz double ended tuning fork gyroscope was implemented. The gyroscope has two detection modes; the first mode detects the angular velocity about a z-axis perpendicular to the tuning fork plane (x-y plane), while the second mode detects the angular ... 詳細を見る
Parametric Study of Electrolyte-Supported Planar Button Solid Oxide Fuel Cell
Fuel cells are devices that convert chemical energy of a fuel into electrical energy through electrochemical processes. One of the types of fuel cell is the Solid Oxide Fuel Cell (SOFC) that uses solid ceramics for electrolytes. Numerical simulation involves constructing a mathematical ... 詳細を見る
