Airliners are often subjected to dangerous atmospheric and weather hazards among which lightning strikes represent a threat for flight safety. Recently, the use of Carbon Fibers Reinforced Composites as structural parts in aircrafts as an alternative to traditional metallic materials. ... Read More
In this paper a methodology for calculating loss within contactless inductive power transmission systems, resulting from hysteresis and eddy current effects, is presented. The usage of the mathematical models of Stoll and Steinmetz for the determination of core loss with COMSOL is ... Read More
An interaction of aluminum aircraft skins with a laboratory-simulated, low-level, long-duration, continuing current representative of a natural lightning flash was modeled with COMSOL Multiphysics. For the analysis of the lightning direct effects on aircraft, the external environment is ... Read More
Implantable biosensors have the potential to revolutionize the healthcare industry by allowing patients and their health care providers to continuously monitor blood pH levels, pCO2, proteins, metabolites, and a wide variety of other biomolecules. These devices need to operate completely ... Read More
Microwave drying of foodstuffs is a complex interplay of mass, momentum, and energy transport coupled with large deformation of the solid. To be able to better understand the microwave drying process, a fundamentals-based three dimensional (3D) multiphase porous media based model is ... Read More
In the context of non-destructive evaluation methods, eddy-current testing plays a prominent role in crack-detection problems, due to its various attractive features. One of the physical quantities that typically interest us in such type of problems is the – complex – coil impedance and ... Read More
Surface Acoustic Waves (SAW) is the acoustic wave that propagates along the surface of the substrate with amplitude decaying exponentially away from the surface. A basic SAW device consists of two IDT’s on a piezoelectric substrate such as quartz. Surface Acoustic Wave can be ... Read More
Acoustic Imaging of hand movement is being studied with COMSOL and Matlab. A hardware implementation is being pursued that will be an array of 16x16 ultra-sonic speakers placed in a grid facing a similar grid of 16x16 microphones, operating at 40kHz. COMSOL is used to repeatedly ... Read More
A compression driver is a certain type of electrodynamic loudspeaker which has a phase plug with slits in front of the diaphragm. The slits are narrow enough that the so-called viscothermal effects are of significant importance. In this paper a 2D axisymmetric finite element model of a ... Read More
Studying teeth grinding behavior and other oral conditions requires the ability to accurately measure the pressure on the teeth. Placing a sensor in the mouth requires small size devices with powering and measurement techniques that do not hinder the normal life of the patient. To meet ... Read More
