The described Poisson-Nernst-Planck-Navier-Stokes nonequilibrium mathematical model is a powerful tool for analysis of the reaction transport processes in various microfluidic devices, namely, geometrically complex microfluidic structures with polarizable dielectric walls or dep…
The AFM cantilevers offer interesting prospects as biological and chemical sensors with very high sensitivity. To allow the adsorption of chemical species on the functionalized surface of cantilevers, these cantilevers are previously coated with a thin film of gold or silver. Th…
The presented work considers two approaches to use a CFD method for modelling the hydrodynamic field of fishing gear net structures. These approaches are based on the COMSOL Multiphysics software use allowing to model physical fields of various bodies flow of a flow. For an esti…
The re-examination of the colloid filtration theory revealed that it is crucial to consider the effect of surrounding solid grains on the flow field in order to gain more realistic results. The application of the colloid filtration theory on the air bubble showed that more collo…
A model describing the dynamics of a floating body by solving the NS-equations in a moving grid framework with free surface is presented. The model has several interesting features, like the peculiar way of describing: a) the grid movements; b) the slip boundary conditions in pr…
Electrical resistance tomography is a technique able to identify solid/liquid distribution in packed beds by identification of the bed conductivity and its subsequent modelling as a function of electrical properties of each phase. It can be performed via an array of equispaced e…
The applicability of the present model of an ideal two-probe impedance measurement, treated as a current injection/extraction problem, is demonstrated for a fairly good conductor, in this case a nickel-base superalloy. However, the scope of this model may be extended to good sem…
It is concluded that the presented simulation environment Matlab/SimuLink/Comsol is capable of solving a large range of integrated HAM problems. Furthermore, it seems promising in accurately solving modelling problems that are caused by the presence of different time scales and/…
