Non-conventional hydrocarbon resources become more and more challenging object for energy producing companies throughout the world. Being already known and long-explored method, the electromagnetically (EM) assisted recovery constitutes a promising idea of technology for deposits of such a kind. COMSOL has been used recently for modeling the thermal multiphase flow through porous media in the ...

The well known Pierce design of electron and ion diodes is the base of particle source extraction systems [1,2]. It was heavily studied up to 1960 with analog computing and it now offers us a known case against which to compare the precision of fluid and particle tracing codes. The ideal model assumes zero particle kinetic energy at cathode emission, which is well matched in many sources: the ...

Mass spectrometry is an analytical technique widely used in the scientific community to determine chemical composition of sample compounds. Typically, mass spectrometers perform their analysis under vacuum conditions, though atmospheric pressure mass spectrometers are becoming more prevalent. With the development of atmospheric pressure mass spectrometers, techniques such as FAIMS (Field ...

There is urgent need to monitor dental and oral diseases, such as tooth decay, gum diseases, and teeth grinding. Such monitoring can be achieved by embedding sensors in the mouth. This technique faces some difficulties. The first is how the power needed for the operation of the sensors and the associated electronic chips can be generated. This power can be generated using the pressure exerted by ...

Membrane-based tangential flow filtration (TFF) cassettes are used for the clarification, concentration and purification of fluid streams containing macromolecules of proteins. In TFF, the protein fluid is pumped tangentially along the surface of the membrane. The feed flow along the length of channel between two membranes causes a pressure drop from the feed to the retentate end of the channel. ...

Use of the terahertz(THz) region, which is unexplored frequency band, is investigated and expected for the next-generation high-speed wireless communication. In this presentation, we propose a monolithic integrated device by using mesa-shaped compound semiconductor and a thin-metal broadband antenna which is capable in THz operation, and we analyze several characteristics of the device by using ...

Considering a liquid drop in relative movement with respect to the air flow at uniform velocity, the liquid will be driven to the surface by the viscous friction. Internal vortices will appear inside the drop. This problem has already been studied in fluid mechanics and is well known as a classic problem. The idea of the present work is to resume the same analysis in a porous medium within a ...

An alluvial aquifer system has probably conceived as a numerical modeling hell. We have chosen COMSOL Multiphysics® for two reasons: 1) FEM methods allow to use complex geometries; 2) multiphysics simulation permits to run a single model with all phenomena. We built a section with these physics: a) Darcy's law, b) Richards' equation, c) ALE to show surface deformation, d) Hydrogeologcal ...

In heating upgrades, most attention is paid to the boiler. When upgrading to HR++-boilers (eff of 107%) however, difficulties may occur since the high efficiency boilers are designed for water temperatures around 40°C, while the old radiators are designed for water temperatures higher than 60°C. The resulting mismatch may lead to reduced performance, a larger carbon footprint and increased ...

When the production capacity of micro chemical plants is increased by numbering-up approach, it is important to realize the uniform flow distribution among the parallelized microreactors. In addition, a blocked microreactor needs to be identified as early as possible to achieve the stable long-term operation of micro chemical plants. In this research, a system that can detect a blocked reactor by ...
