This paper deals with the design of a viable thermal management solution using La5Ca9Cu24O41 layers for heat channeling. The simulations are carried out with the finite element method using COMSOL Multiphysics Heat Transfer Module. COMSOL 4.2 was used to model and optimize silicon devices. Malfunctioning elements on silicon devices are sometimes converted into hotspots resulting in the ...

Surface aeration systems are used in the wastewater treatment industry for the transfer of oxygen in the activated sludge process. These systems are capital intensive and also require a significant amount of energy to operate. Scale-up and design of these systems is largely empirical, and due to the size of these systems, modifications for experimental testing can be economically prohibitive. ...

Accurate metrology of radiotherapeutic absorbed dose to water requires assessing the radiation induced temperature change. The most direct method for doing this is water calorimetry, for which the established technique involves the use of slender thermistor probes that are sealed within a glass vessel containing high-purity water. The probes and vessel perturb the radiation field, via ...

Computer simulation is mandatory for the optimization of electromagnetic devices. Here we concentrate on two classes of devices operating in the MHz and GHz range, namely microwave ovens and TEM cells for electromagnetic compatibility testing. In particular we concentrate on the issue that numerical results are usually different from the experimental ones and this can be due, among others ...

This paper presents a successful step towards the development of a “web-based laboratory” for teaching basic, and even advanced, electromagnetic concepts. The main idea is to develop a reusable model for the student to be used exactly as a hardware experiment in a physical laboratory, where he/she can change some of the experiment\'s physical parameters and get corresponding results. The two ...

Multiphysics simulation has been used extensively in our research for fluid flow and heat transfer applications. Our projects include: simulation of fluid dynamics in an active liquid heat sink for CPU cooling, impeller design for a pipe flow generator with computational fluid dynamics (CFD), investment casting with plastic rapid prototype patterns, phase change materials with rapid prototyping ...

COMSOL Multiphysics® has been used to develop assessment tools for the NASA-sponsored Precision Combustion, Inc. (PCI) regenerable Microlith®- based adsorber modules. The Full Scale Water Removal (FSWR) PCI Microlith® was initially modeled for comparison with exit velocity data, measured while exterior canister was removed. Measurement data as well as flow analysis showed that the velocity ...

Even though sonochemical reactors have been studied extensively for decades, there is limited data on their characterization when the volume of the sample is fixed. The Acoustics Module and COMSOL Multiphysics® software are used to resolve the pressure field. The validated numerical model will be used to compare different configurations; changing the Height (H), diameter (D) of the reactor and ...
Modeling of Noise Produced by Offshore Wind Turbines with Different Foundations and Effects on the Marine Environment - new

Vibration produced by offshore wind turbines during their normal operation transmits through the tower into the foundation where it interacts with the surrounding water and is released as noise. The noise produced by offshore wind turbines can be detected by fish and marine mammals and may lead to alteration of their behavior. Given that noise is emitted at the interface between the foundation ...
