In this paper an axisymmetric model of annular linear electromagnetic induction pumps using numerical methods and four approaches (two transient and two quasi-stationary) with different complexity is studied. Comparison of integral characteristics is performed between numerical ... Read More

The manufacturing of high quality injection molded parts requires a deep understanding of material properties, process parameters and product design. The behavior of a polymer during the injection molding process and the performance of the final part are strongly determined by the ... Read More

Sound absorption in porous materials with rigid frame and open porosity can be very effectively estimated by applying the Johnson-Allard model in order to substitute a porous medium with an equivalent effective fluid and then utilise the Helmholtz equation for time-harmonic acoustics. ...

Multigrid methods (MG) belong to the fastest solvers for partial differential equations. The key for this is an appropriate composition of the algorithmic components [1,2,4]. The multigrid solver implemented in COMSOL Multiphysics® is analyzed with respect to components and with respect ... Read More

Moisture can cause serious damages in different building components therefore the heat and moisture calculation in building constructions are important tasks. In the current paper, two different multi-layered walls, mainly consisted of wooden materials and mineral wool, are analyzed. ... Read More

Fluid injection in deep wells is a basic procedure in geothermal permeability enhancement. The retrieved changes of Pressure and Temperature are subsequently considered as sources of incremental stress and strain changes, using the elastic model from COMSOL Multiphysics®, which are then ...

: One of the most commonly used techniques for quantification of beating forces exerted by cardiomyocytes is culturing them on a bed of vertical microcantilevers or microposts. The position of the microcantilevers is observed through advanced imaging techniques and the displacements are ... Read More

Double walls provide stability to the structure and separate the controlled indoor climate from the outdoor fluctuating environment. In this study we want to receive more insight in the heat exchange between the walls through the cavity in between, by computer simulations and ... Read More

Metal contaminants and organic pollutants are affecting aquatic environments in urban and industrial zones. Mangrove trees are capable of absorbing metal ions and organic pollutants. To estimate the remediation potential, a two dimensional model of water and substance flow in the soil ... Read More

In the production of high quality materials by a heat treatment, it is indispensable to accurately predict the temperature inside the furnaces being employed. In this work we develop a turbulent combustion model for the heat being released by gas burners inside a shaft kiln. Turbulent ... Read More
