Using a Realistic Human Head model to simulate the effect of electrical stimulation can be useful in understanding field distribution in the brain and therefore, the actual point of stimulation before doing it on human subject. With the help of this model, parameters like the stimulus strength as well as electrode placement and its effect can be tested much more easily while targeting a ...

Calculations were carried out for the water model of the investigated tundish, represented on a scale 1:3. Numerical calculations enable to estimate the fluid flow velocities, pahtlines and other parameters. Calculations were done for two different grids. Based on the results, the flow structure in the investigated tundish was obtained.

The kinetic interface-sensitive tracers (KIS tracers) are used to give a partial picture of the spreading, mixing and plume migration of supercritical carbon dioxide (scCO2) in the deep saline aquifer by estimating the interfacial areas between scCO2 and brine during the injection of scCO2. To get a better understanding of the KIS tracer reaction and transport processes in the two-phase flow ...

In a water based electrolytic polishing process, the formation of molecular hydrogen at the cathode is unavoidable and it can contribute to the formation of surface defects at the anode side. This paper presents the work to model and simulate the molecular hydrogen flow inside radio frequency cavity geometries and compares it with the presence, type and relative position of certain defects in ...

Macroscale ultrasonic separation is a new filtration technology, with various applications such as cell clarification, cell therapy, blood-lipid separation, oil-water separation etc. These systems use piezoelectric transducers to create standing waves in fluid-particle mixture. Suspended particles get clustered by action of acoustic radiation forces and are separated out by enhanced gravity ...

We present the results of full-waveform time-dependent finite-element modelling of coupled seismoelectromagnetic wave propagation in fluid-saturated porous media. To describe the seismoelectric response of the system a new set of equations is developed which couple the poroelasticity theory and Maxwell’s equations via flux/force transport equations in a thermodynamical sense. The coupling ...

The results of two thermal response tests recently performed on two vertical borehole heat exchangers (BHEs) are presented. The BHEs have the same cross section and a depth of 100 m and 120 m respectively. The evaluation of the thermal properties of the ground and grout are performed by a finite-element simulation method, developed through the software package COMSOL Multiphysics 3.4.

One of the major applications for dielectrophoresis is the selective trapping and fractionation in lab-on-a-chip devices. Nevertheless, many-particle effects due to high concentrations of biological material around electrodes can cause a rapid decrease of trapping efficiency in dielectrophoretic devices. In this contribution we present a new approach based on a drift-diffusion dynamics to study ...

Fresh fruits and vegetables are gaining importance in the human diet because they contain many beneficial compounds. Among these compounds, phenols are of vital importance due to their antioxidant properties. It is well evident from previous researches that the skin of red grapes is considered a good source of phenols. The aim of this work is to simulate the extraction procedure of phenols in ...

Atherosclerosis causes the deposition of plaque on the inner walls of arteries, which leads to restricted blood flow. Using the balloon angioplasty procedure, stents can be inserted and expanded in the atherosclerotic artery. We used COMSOL Multiphysics Structural Mechanics, Solid Stress-Strain module to perform static, large deformation analyses. Our results show that lower stent stresses were ...
