Heterogeneous materials with different phases, are conductive and insulating (dielectric), and are physically present in different natural materials as e.g. atmospheric ice. Jonscher’s proposed ‘universal dielectric response’ is not sufficient for such materials, as it only reflects ... Read More
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 ... Read More
Nowadays, spot laser welding is a full-fledged part of industrial manufacturing and is routinely used due to its advantages. It generates very located temperature gradients, and therefore, induces small distortions in the pieces. The COMSOL Multiphysics® software is used to model the ... Read More
A comprehensive mathematical model that includes mass and heat transfer was developed for the transport of gas mixture of carbon dioxide and methane through hollow fiber membrane (HFM) contactor. COMSOL Multiphysics® was used in solving the set of partial, ordinary and algebraic ... Read More
In certain cases, the accuracy of measurements with a rotational rheometer can be influenced by inefficient thermal management, by the heat generated in the sample, or by rod-climbing due to the Weissenberg effect. We investigate the effect of these phenomena with simulations in COMSOL ... Read More
Streamers are considered as main cause of electrical breakdown in air at atmospheric pressure. A streamer is an ionization wave propagating in neutral gas which is converted into low-temperature plasma behind its front. A streamer model is based on drift-diffusion approach where space ... Read More
This paper studies oxide forming on titanium, during cold gas dynamic spraying with air. This is a quite new spraying method, which can be used to spray material having high affinity for oxygen. The model allows for the diffusion of oxygen through the oxide layer, reaction on the oxide ... Read More
Simulation of the flow behaviour of non-Newtonian fluids with high viscosities leads to special material models with specific material parameters. In this presentation, a material model consisting of 4 material parameters describing the flow itself and also the wall slip is presented. ... 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. ... 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 ...
