Chemicals are an integrated part of our daily life. While chemicals are significant contributor to a nation’s economy, sound management of chemical production is essential for environmentally friendly operation without maximizing operational costs. Next generation technologies must be ... En savoir plus

Self-heating is a problem to consider for Ultrasound Imaging probes. Since the probe is in contact with the skin, it’s necessary to find a solution to lower the front face temperature in order to avoid patient discomfort, even at the most demanding operating condition. One solution ... En savoir plus

A design for the thermal management of the media used for packing Li-ion batteries used in hybrid and electric vehicles has been developed. The design satisfies all thermal and physical issues relating to the battery packs used in vehicles such as operating temperature range and volume, ... En savoir plus

The paper presents a methodology to account for local mean-flow effects on thermo-acoustic instabilities to improve typical calculations performed under the zero-Mach number assumption. A 3D FEM model of a simplified combustor is solved with COMSOL Multiphysics® Pressure Acoustics ... En savoir plus

Packed beds are important in the chemical industries. Computational fluid dynamics (CFD) can simulate detailed flow and scalar transport in packed beds for improved understanding and quantitative information. We present simulations of single-phase gas flow, conjugate heat transfer and ... En savoir plus

Museum buildings strive for a stable indoor climate to reduce the risk of cultural object degradation. An incorrect temperature or relative humidity can induce or accelerate deterioration processes such as biological, chemical or mechanical degradation. In order to reduce these risks, ...

Using modeling software such as COMSOL Multiphysics during the design phase, an approach called “simulation-led design”, allows ideas to be both inspired and validated by the use of simulations. Then, using simulations after the product is designed can shorten the prototype-testing ... En savoir plus

The research documented herein was funded by a research contract between the Research Reactors Division (RRD) of Oak Ridge National Laboratory (ORNL) and the University of Tennessee, Knoxville (UTK) Mechanical, Aerospace and Biomedical Engineering Department (MABE). The research was ... En savoir plus

Lorentz Force Velocimetry (LFV) is a non-contact measurement technique used to determine flow rates in electrically conducting fluids by exposing the flow to an external magnetic field and measuring the Lorentz force acting on the magnet system. Typically, for LFV applications real and ... En savoir plus
