Modeling and Characterization of Superconducting MEMS for Microwave Applications in Radioastronomy
Superconducting GHz electronics circuits are frequently used in Radio Astronomy instrumentation. The features of these instrumentations can be significantly improved by using tuneable capacitances, which can be realized by electrically actuated, micromechanical bridges (MEMS) made of ... Read More
High Vacuum Gas Pumping and Boundary Coupling
Many scientific instruments are based on high vacuum equipment with a gas pressure maintained in the order of 1 Pa or below. The gas flow in the low pressure limit, called the molecular flow regime, is a case of transport with zero viscosity. The ability to solve an integral equation on ... Read More
Lava Tubes at Shallow Depth
Many theoretical studies concerning lava tubes focus on the thermal disturbances generated on the earth surface. Recently a solution was suggested, where a lava tube located at a great depth h in the soil, where the ratio between h to the major axis of the ellipse a is higher than 10. ... Read More
Simulation of Surface Chemical Reactions in a Monolith Channel for Hydrogen Production
This paper intends to show a model of a monolithic reactor for the autothermal reforming process (ATR), a process that uses hydrocarbons to produce H2. The ATR chemical reactions take place on the surface of monolith channels coated with a catalyst. The isothermal ATR reactor is modeled ... Read More
Benchmarking as Key Element of Confidence Building in Safety Assessments for Radioactive Waste Disposal
Verification of the codes applied for assessment of the long-term repository safety is typically one of the quality assurance requirements demanded by regulatory bodies, in the disposal of radioactive waste. In this paper, an internationally organized benchmark exercise is presented, in ... Read More
On Boundary Conditions for CSEM Finite Element Modeling, I
In this study, we propose an absorbing boundary domain (or condition), which is really simple but still efficient for the 2.5D finite element (FE) analysis. The main application is to simulate the electromagnetic (EM) waves related to the marine controlled source electromagnetic (CSEM) ... Read More
Modeling Ion Motion in a Miniaturized Ion Mobility Spectrometer
Ion mobility spectrometry provides fast detection of very low concentrations of chemical substances. Simple instrumentation combined with high sensitivity and high selectivity are the advantages of this technique. One well established field of application is the detection of hazardous ... Read More
Comparing Equations for Two-Phase Fluid Flow in Porous Media
Various types of equation system formulations for modeling two-phase flow in porous media using the finite element method have been investigated. These allow for equation manipulation such that the main differences between the formulations are the dependent variables that are solved ... Read More
Numerical Modelling of Electrophoresis Applied to Restoration of Archaeological Organic Materials
Restoration of archaeological materials from oceans is a major activity of Arc’ Antique. Organic materials such as wood, tissues, leathers, papers and ceramics found in sea water are always impregnated with salts. Rinsing such archaeological objects with pure water to extract the salts ... Read More
Modelling of the Temporal Analysis of Products (TAP) Reactor with COMSOL
A TAP reactor is a fixed-bed catalytic reactor operated in pulse (transient) mode under very low pressures. It has become a very important tool in catalytic studies as it fills the material and pressure gaps existing between practical conditions and high vacuum – monocrystal techniques. ... Read More
