The transfer of sucrose and fructooligosaccharides to melon and water to solution was modeled based on generalized form of Fick’s second law for simultaneous diffusion and resolved by the finite element method using the software package COMSOL Multiphysics® software. The diffusion coefficients, the mass transfer coefficient and the Biot number were determined using the simplex optimization ...

Augmented reality is predestined for visualization of electromagnetic fields in air or inside transparent matter. Real existing objects are studied and invisible electromagnetic fields are added as virtual objects. Hence, experts as well as students are able to connect electromagnetic fields easily with studied objects. They can concentrate on physical effects instead on reading figures. Here, ...

We demonstrate the use of Comsol Multiphysics with Matlab to model signal generation in wide-bandgap semiconductor radiation detectors. A quasi-hemispherical detector design is compared with a simple, planar detector. Results show that the quasi-hemispherical design can simply and effectively compensate for the poor hole transport of most compound semiconductor materials.

Petroleum reservoir simulation is a process of modeling the complex physical phenomena inside a reservoir. This study presents an application of an analytical based numerical scheme so called the Boundary Element Method (DRBEM). It is proven to be able to provide a computationally efficient means of handling single and multiphase flow in a homogeneous medium through the comparison study with ...

Several undergraduate programs include the “Heat transfer” subject and, in our experience, it is hard for the students to grasp the concepts that are presented in the course. With this in mind, we designed and constructed an apparatus for the experimentation of heat transfer in a short bar. It was observed, that the time required to perform the experiment was so long, that the didactic aim was ...

Circuit board failures are often ignored because they could be impreceptible. This simulation examines how internal layers around a soldered pin via subject to temperature changes during the soldering process are affected, show the forces involved and determine breaking points. A 2D thermo-mechanical model of a soldered pin is achieved in two simulation steps. First, a connecting pin already ...

The Giant Magneto Resistance (GMR) effect is a quantum mechanical effect which can be observed in systems consisting of thin alternating ferromagnetic and non-ferromagnetic layers. Simulation using COMSOL allows the evaluation of the magneto-resistance ratio and the electrical resistances of realistic CPP-GMR devices and opens the possibility to study new device materials and designs.

Bone resorption around hip stems, in particular periprosthetic bone loss, is a common observation post-operatively. A number of factors influence the amount of bone loss over time and the mechanical environment following total hip replacement (THR) is important. Conventional long stem prostheses have been shown to transfer loads distally, resulting in bone loss of the proximal femur. More ...
