In some power electronic applications the available coolant temperature is close to maximum and controlling operating temperature becomes more challenging, for which new thermal management schemes must be considered. COMSOL predicts the 3D fluid behavior and 3D temperature distribution within an actively cooled power electronic structure. A solution mapping method is implemented to more ...

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 takes too long, so electrophoresis was used to improve the salt extraction. The objective of this ...

Fresh fruits and vegetables are gaining importance in the human diet because they contain many beneficial compounds. Among these compounds, phenols are of vital importance due to their antioxidant properties. It is well evident from previous researches that the skin of red grapes is considered a good source of phenols. The aim of this work is to simulate the extraction procedure of phenols in ...

COMSOL Multiphysics is widely utilized in the modeling of dynamics of technological and manufacturing processes. At the same time the investigated technological and manufacturing processes are generally described by systems of partial differential equations as distributed parameter systems. This paper presents actual possibilities of control of systems modeled by COMSOL Multiphysics as ...

A three dimensional COMSOL Multiphysics, transient analysis, diffusion model has been adopted to model the transfers of water in the industrial concrete floors. To take into account the different initial saturation levels at the different levels of the slab, the model is divided into three subdomains. The rise of the waterfront is also simulated and the air overpressure thereby developed at the ...
ComsolGrid – A Framework For Performing Large-Scale Parameter Studies Using COMSOL Multiphysics and Berkeley Open Infrastructure for Network Computing (BOINC)

BOINC (Berkeley Open Infrastructure for Network Computing) is an open-source framework for solving large-scale and complex computational problems by means of public resource computing (PRC). In contrast to massive parallel computing, PRC applications are distributed onto a large number of heterogeneous client computers connected by the Internet where each computer is assigned an individual task ...

This paper presents a numerical model based on the mild-slope equation (MSE for short) solved using the PDE mode of the software COMSOL Multiphysics suitable to reproduce the propagation of small amplitude tsunamis in the off-shore field. The model solves the governing equations in the frequency domain and allows the reproduction of the frequency dispersion for broad banded spectrum sea states. ...

An electromagnetic horn is a device used in particle physics to produce a strong pulsed toroidal magnetic field and to focus charged particles toward a detector. A multiphysics analysis is performed to assess the stress level inside the horn structure. In steady state regime, the horn is submitted to a thermal static stress due to thermal dilatation. Then, every 80 ms a strong magnetic field ...

For the numeric investigations of the high temperature compact heat exchanger two numeric models with and without the regards of the velocity field development were used. The results of the comparison of the numeric and experimental data confirm the necessity of regarding the velocity field development for the compact heat exchangers. The two-dimensional simulation task with the regard of ...
