Thermoelectric materials are one of the most promising materials for future and nowadays energy harvesting devices, as they can convert heat into electricity and vice-versa. The efficiency of thermoelectric materials is related with the figure of merit, ZT. Our work deals with the determination of the parameters that affect the measurement of the ZT with the Harman technique and the best ...

Mathematical Modeling has a long history in developmental biology. Advances in experimental techniques and computational algorithms now permit the development of increasingly more realistic models of organogenesis. In particular, 3D geometries of developing organs have recently become available. In this paper, we show how to use image-based data for simulations of organogenesis in the COMSOL ...
Modeling of Wettability Alteration during Spontaneous Imbibition of Mutually Soluble Solvents in Mixed Wet Fractured Reservoirs - new

Mutually-soluble solvents can enhance oil recovery both in completely and partially water wet fractured reservoirs. When a strongly or partially water-wet matrix is surrounded by an immiscible wetting phase in the fracture, spontaneous imbibition is the most important production mechanism. Initially, the solvent moves with the imbibing brine into the core. However, upon contact with oil, as the ...

Nowadays, gas and nuclear waste storage, shale gas and EOR exploitation rise the need to understand and predict the fate of multiphase flows in the underground. Various formulations for multiphase flow arise from different linear combinations of governing equations and choice of associated unknowns. Each formulation has its own benefits and drawbacks; and the optimal may vary depending on the ...

Crystallization phenomena are of first interest in several industrial applications (polymer forming processes, metallurgy, phase change flow, energy storage...). A classical way to model the crystallization evolution is using the Nakamura kinetics law. In this paper, a novel physics interface is developed using the Physics Builder of COMSOL Multiphysics® , which accounts for the resolution of ...
3D Multiphysics Modeling of Bulk High-Temperature Superconductors for Use as Trapped Field Magnets - new

The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of superconducting materials can lead to increases in efficiency, as well as power density, which results in reductions ...

Vibration and music therapies are non-invasive treatments having effective results although their basics are still disputed. By the application of COMSOL Multiphysics® software for modeling and analysis, some of the nonlinear physical phenomena laying on these applications may be clarified. Acoustic environmental stimuli at different intensities are continuously interacting with our bodies, ...

We have simulated alignment and movement of multiple particles under Dielectrophoresis (DEP) using the Particle Tracing Module in COMSOL Multiphysics® software with particle-particle interaction taken into consideration. We are able to do efficient modeling for both 2D and 3D cases. With this work, we are able to shed important insights into the process of pearl chain formation, antenna-like ...

The formation of space charge clouds is a well known problem that affects thermionic emitters in regimes of high current emission. Although some analytical models have been presented, suitable for 1D geometries, the modeling of the problem in complex 3D structures remains a challenge due to the mutual coupling between electron trajectories and field they produce. Here we propose a model able to ...
