Temperature measurements of the subsurface are available due to hydrocarbon exploration in the project area, where the average drilling depth is about 2-4 km and the deepest well reaches about 8.5 km. Since the data is heavily uneven distributed, standard interpolation techniques did not deliver satisfying results. This is why numerical modeling was applied to assess the thermal regime of the ...

Currently there is much interest in electromagnetic metamaterials [1-9]. In our work we have focused on design of tunable metamaterial which can be made within available technology. In proposed design we use metallic split-ring resonators and thin-wires (Figure 1). Moreover we have decided to introduce nematic liquid crystal layer in design to obtain tunability (Figure 2). One can control ...

Drug therapy of the posterior segment of an eye is very challenging due to the difficult accessibility. Modern drugs often are large molecules, such as peptides, antibodies or oligonucleotides which are administrated, e.g. by intravitreous injections which requires clinical conditions. Computer modeling can be helpful in designing new and less invasive routes of drug administration. COMSOL is ...

The energy pay back is one of the most interesting field especially in the steel industry where this contribution is strictly connected to steams and emissions inside and outside the plant. Perhaps, this application is sometimes disturbed by a strong variation of emissions (\"off gas\"). One example is the arc furnace where the process is very discontinuous and there are many fluctuations in the ...

This paper presents thermo-mechanical models for predicting the strength of polymer laminates loaded in tension or compression exposed to one-sided radiant heating by fire. The first part is the fire simulation where the FDS model is utilized. The FDS model generates a solution of several state variables, such as pressure, temperature, heat, velocity vector. In the second part, COMSOL heat ...

The Swedish Nuclear Fuel and Waste Management Co (SKB) is responsible for final disposal of spent fuel and radioactive waste. SKB operates SFR, an underground waste repository in crystalline rock. The evolution of groundwater flow within the repository needs to be estimated considering different options for the design of the engineered barriers. The goal is to predict the effects of flow and ...

The possibility to detect and probe molecules in microfluidic devices gives rise to interesting applications. There are different approaches how to detect and probe particles, but a common step, for most methods, is to place the particles on a sensor. This can be done by applying external field gradients, or in this case by utilizing gravitational and hydrodynamic effects. Therefore, the sensor ...

Hydrogen, the most abundant element in the universe, has great potential as an energy source, and can be generated from renewable energy sources. We used COMSOL for the solution of the energy, mass and momentum balance equations that describe the hydrogen absorption and desorption procedure in the metal hydride compressor. Thermodynamic or engineering properties like the reaction enthalpy ??, ...

Presented work is motivated by pre-realization phase of rock heating experiment in underground, testing properties for cyclic energy storage. Heating unit, installed in large borehole from end of a tunnel, is fixed to the rock face with the geo-polymer. Rest of the borehole is filled with isolation material. We used the Heat Transfer Module and the Structural Mechanics Module in COMSOL for ...

It is important in designing micro-electromechanical systems (MEMS) to reduce the variability of design parameters caused by manufacturing tolerances and material properties. At NXP COMSOL has been used to investigate many aspects of the design, such as the Q-factor, anchor losses, thermal behavior, parasitic capacitance of the resonator and more. Quartz crystal resonators are used in many ...
