Flows in highly heterogeneous media are found in many practical fields, such as hydrology, petroleum engineering, and chemical engineering. The case of two-region heterogeneous media (fractured media, catalytic beds, etc.) plays a fundamental role. The different questions associated to this specific case are illustrated in this paper for two different kinds of transport: (i) flow of a slightly ...

The aim of this work is to study tissue morphogenesis as a consequence of the constitutive cells dynamics. Tissue morphogenesis is modelled as a cellular system coupled with a global chemical control. p> Two concrete examples are presented, the secondary growth of conifer trees and the epithelial invagination.
In this presentation we outline our recent work on Magnetic Liquids, and the great number of application areas these are used. Ferrofluids are nanometer sized magnetic particles, covered by a surfactant, suspended in a carrier medium compatible with the surfactant material. Ferrofluids are applicable to a great and ever increasing number of application areas, such as: • Liquid Seals and ...

COMSOL Multiphysics has been used as a supporting tool to our experimental research. Temperature rise inside biological samples was evaluated, giving us the possibility to study the heat damage induced in the tissue, the mechanism of photothermal processes, and to optimize surgical procedures. --------------------------------- Francesca Rossi was one of the keynote speakers at the COMSOL ...

In this presentation, a 1.31/1.55μm wavelength division multiplexer (WDM) based on a 1-D linear array photonic band gap (PBG) structure interconnected with an input/output 2-D PBG array is presented. The linear array coupler parameters were obtained using eigen-mode expansion (EME) aided by optimization techniques based on global and local simplex search algorithm. The design is verified ...

In this study, a model cast in COMSOL Multiphysics has been developed for the analysis of heat transfer and phase change during laser-assisted direct imprinting processes. The features of this model include the employment of temperature-dependent thermal properties, the use of equivalent specific heat for the treatment of latent heat of fusion, automatically switching the thermal contact ...

Sensing electrodes array model of 3-Dimensional ERT/ ECT dual modality is established by using the software COMSOL. According to the uniformity of sensitivity field distribution, the correlation coefficient and the reconstructed image space resolution, the ECT/ERT dual modality sensing electrode arrays are optimized. Experimental results show that the optimized sensing electrode array of the ...

We present results of simulations of a thin liquid film flowing down an inclined plane. Within the lubrication approximation, and assuming complete wetting, the film height is the solution of a time-dependent non-linear fourth order partial differential equation, which is solved using COMSOL.Appropriate initial and boundary conditions are proposed and the influence of the height of the precursor ...
