High frequency side-scan sonar, to be fitted on a miniaturized submersible explorer, have been simulated and built. The purpose of this study is to see if COMSOL Multiphysics® can be used to predict the performance of the sonar, especially the beam width, setting the resolution of the system. Four models were created, from simple 2-D geometries to more complex 3-D models. The simulated beam ...

In biomedical research the use of animal models gives rise to several ethical problems. COMSOL Multiphysics® may be used as a non-animal technique, very useful in overcoming all these concerns. In this presentation a particular application in dermatology is shown. Bioheat equation mode and diffusion approximation were used to design a theoretical model of blue LED light interaction with an ...

This presentation is concerned with the modelling of deformable non-Newtonian Flow using COMSOL Multiphysics. This general modelling approach has more concrete applications such as paper coating in a metering size press, meniscus location by PIDS to mention a few.

This research presents a model describing the behavior of fluids during a septic filling processes. Numerical simulations were performed to investigate the laminar flow and rheological behavior of shear thinning and Newtonian fluids in 3-dimensional steady state and time-dependent configurations. The mass and momentum balance equations were solved with the finite element method using ...

Primary reference standards for determining absorbed dose to water in radiotherapy beams used at cancer clinics and hospitals ultimately must make reference to the temperature change in water produced by ionizing radiation. The most direct experimental technique for this purpose is water calorimetry. Since the dose distributions delivered by such beams are nonuniform, temperature signals ...

Two-phase electrophoresis is a separation method that combines aqueous two-phase partitioning with electrophoresis and has promise for large scale recovery of biological products. Aqueous two-phase systems formed by adding two polymers, like dextran and polyethylene glycol, to water provide some separation of dissolved species due to differences in solubility of solutes between the phases. COMSOL ...

We present an implementation of the Structural Mechanics module of COMSOL Multiphysics to model the state of stress associated with the emplacement of large volcanic edifices on the surface of a planet. These finite element models capture two essential physical processes: (1) Elastic flexure of the lithosphere beneath the edifice load, and (2) Pressurization of a magma-filled chamber that serves ...
High-intensity discharge (HID) lamps are highly-efficient light sources with many applications. Depending on the dimensions of the electrode, lamp current, and waveforms, the plasma may attach to the cathode in a diffuse mode, that covers the electrode tip surface, or a localized mode where heating and current transfer occur in a local region of the electrode surface. The localized mode is ...

Atherosclerosis affects the arterial blood vessels causing stenosis in the arteries because of which the artery hardens resulting in loss of elasticity in the affected region. In this paper, we present an approach to model the pulsating flow of blood through such an atherosclerosis affected region of the artery using the finite element method. We further discuss the statistical model used to ...

The purpose of this study was the optimization of an industrial furnace from a thermal point of view. Such a cylindrical furnace contains an Al-Mg molten alloy covered by a KCl-NaCl molten salt layer floating on it to prevent alloy evaporation. When tilting the cylindrical furnace, it was necessary to compute the relation between the salt and alloy volumes and the area of the liquid alloy/salt ...
