Introduction: Flexures are low-cost bearings that are capable of providing motion guidance with high repeatability and low friction (Figure 1). However, applications of flexure bearings are often limited by their low range. This is because motion guidance in flexures is provided by ... 詳細を見る

For the last two centuries, the conventional Fourier heat conduction equation has been used for modeling a diffusive nature of macroscale heat conduction by considering the energy conservation and Fourier's linear approximation of heat flux. However, it cannot accurately predict heat ... 詳細を見る

Thermography measurements on metallic thin films are challenging due to reflections from the environment. We present a thin "gold black" absorption layer to deal with this issue. A multiphysics model is introduced to correct the experimentally obtained data for undesirable heat transfer ... 詳細を見る

We have developed Thor: a pulsed power accelerator for performing dynamic material experiments. The design was aided by using the COMSOL Multiphysics® software with the AC/DC Module and RF Module. Our design process involved optimizing the impedance of the system while maintaining a good ... 詳細を見る

Engineering design studies of the feasibility of conversion of the High Flux Isotope Reactor (HFIR) from high-enriched uranium to low-enriched uranium (LEU) fuel are ongoing at Oak Ridge National Laboratory as part of an effort sponsored by the U.S. Department of Energy’s Global Threat ... 詳細を見る

Biosensors based on silicon nanowires are of great interest for ultrasensitive biomolecular recognition of disease specific markers for early stage diagnosis [1]. However, there are limitations on the performance of these nanosensors in solutions at high ionic strength. This is because ... 詳細を見る

COMSOL® software was used to simulate the conductive heat transfer with phase change in the geological formations encompassed in permafrost surrounding a shallow thaw lake. The purpose of the simulation was to verify the adequacy of COMSOL to model such phenomena by comparing the COMSOL ... 詳細を見る

A simple steady-state photo-fermentative biochemical model was developed using the COMSOL Multiphysics'® Transport of Diluted Species physics interface. A dimensionless model seeks optimal physical parameters based on given biochemical parameters found in literature. A parametric sweep ... 詳細を見る

This project involves a simplified biological problem that was used to test the potential of COMSOL Multiphysics® software for cardiac myocyte spatial modeling. We made several assumptions to simplify the biological complexity and to highlight the geometrical structures (i.e., lack of ... 詳細を見る

The dynamic behavior of droplet impingement on a solid surface is important to many engineering applications. This paper studied the dynamic behavior of a droplet impinging onto solid dry surfaces with different surface wettability using the COMSOL Multiphysics® software. The simulation ... 詳細を見る
