This paper presents the solution of a transient electromagnetic problem using COMSOL Multiphysics. The paper also presents a closed-form solution of a transient electromagnetic dipole. The computational solution compares well with a closed-form solution for this problem. This work implements Maxwell’s equations in the RF module and optimizes solver parameter settings to resolve the transient ...

Pyrochemical process based on molten salt electrorefining is ideally suited for reprocessing spent metallic fuels from Fast Breeder Reactors. In this work, a heat transfer analysis of the Electrorefiner cell was conducted to develop a basic tool for designing of the engineering–scale Electrorefiner. The focus of this work is to find out steady state temperature profiles of cover gas and molten ...

In this paper, we develop a mathematical model to simulate the movement of bacteria into and within a capillary segment. Also, we model the transportation through capillary walls by means of anisotropic diffusivity that depends on the pressure difference across the capillary walls. By solving the model using COMSOL, it was possible to predict the concentration of bacteria at points within the ...

We are working on a microfabricated lysing chip that uses a piezoelectric actuator to provide ultrasonic energy to break apart cells. The device contains pillars with varying dimensions. We hypothesize that increasing the aspect ratio of pillars will increase the efficiency of the transfer of ultrasonic energy into the fluid phase and enhance the lysing efficiency. The fluid structure ...

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimise power consumptions of building. One technological approach is to use optical detection using specific absorption lines of CO2 molecules in the infrared domain close to 4.2 μm. Key features for a wider use in public and private buildings are power consumption and price. Such optical ...

The fabrication of piezo aluminium composite modules for sensor and actor applications with mass production technologies is in the scope of the SFB/Transregio 39 PT-PIESA project funded by the (German Research Foundation). After forming of cavities with a width of 0.3 mm into aluminium sheets by micro impact extrusion and the insertion of 0.25 × 0.25 mm2 piezo rods, a joining of the rods into ...

The developments of microsystems for biotechnology have been fast in the last few years, and no sign of slowing down is observed. It has begun with lab-on-chip for genomics, especially for the recognition of DNA sequences, followed by protein reactors and immunoassays, and today the emphasis is on cellomics. Cell-chips are design to monitor the behavior of cells, individually or as a group, ...

The paper deals with simulation of rock heating experiment in underground, testing the rock properties for geothermal application. The modeled process is unsteady heat conduction in 3D. We made several parametric studies to find the possible temperature range with uncertainty in some of the parameters - in particular an interval around the laboratory measured heat conductivity and capacity ...

In this article we present Simulations results of an evaporation reactor for optical layer applications. The thermal simulation concern the source of the evaporated material. An experimental problem is ralated to the shape of the material powder surface: due to the evaporation rate, the surface don\'t keep his flat initial shape and this has a strong effect on the local evaporation rate. In ...
