In the past decades, equilateral polygonal microcavity lasers with whispering-gallery modes (WGMs) have attracted great attentions due to their potential application in photonic-integrated circuits. Compared to the perfect microdisk without deformation, the polygonal microcavities such as triangle, square, hexagonal and octagonal can easily realize the light directional emission and single mode ...

Si-infiltrated SiC porous composites exist in different forms composed of cores of cellular ceramic and skin plates of ceramic matrix composites. Due to high thermal conductivity, low coefficient of thermal expansion, high elastic modulus and high strength, the final product can be a promising candidate for applications in temperatures up to 1500 K such heat exchangers, recuperators and solar ...

Preparative chromatography is an important separation method where the simulated moving bed (SMB) technology is an increasingly used separation process for binary mixtures. Several chromatographic columns are arranged in a ring where the feedings and drains are changed cyclically to maintain a continuous separation. For this reason, an adaptive controller is proposed to adjust the flow rates ...

Hunting Lodge St. Hubertus is one of the most prominent Dutch buildings from the early twentieth century. An extensive study of wind and wind-driven rain (WDR) was conducted to provide insight into the moisture load of the building facade, using measurements and CFD simulations. COMSOL Multiphysics was also used for modeling the moisture transport through the walls of the tower. The model ...

A new type of radiator with a package of combs, to gain a larger area for heat exchange, instead of trapezoidal convector plates, is investigated. The main aim is to find the optimal comb diameter. To solve this problem, CFD (computational fluid dynamics) with COMSOL Multiphysics is used. A chart showing radiator power was produced, which includes radiator power for different temperatures and ...

Pasteurization of solid food undergoing ohmic heating has been analyzed using COMSOL Multiphysics on the basis of a previously validated multiphysics model. The simulation of pasteurization by ohmic heating involves simultaneous solution electrical potential within the food, heat transfer, and the kinetics transport of death of microorganisms. In the model, thermo-physical and electrical ...

Atherosclerosis causes the deposition of plaque on the inner walls of arteries, which leads to restricted blood flow. Using the balloon angioplasty procedure, stents can be inserted and expanded in the atherosclerotic artery. We used COMSOL Multiphysics Structural Mechanics, Solid Stress-Strain module to perform static, large deformation analyses. Our results show that lower stent stresses were ...

Using COMSOL Multiphysics 3.5, a numerical model has been developed to determine the effect of the channel geometry and electrode configuration on cell performance based on polarization curves. The Butler-Volmer equation was implemented to determine the reaction rates at the electrodes. The Conductive Media DC module is used to model the electric fields within the fuel cell.
