This article discusses the RMN import of a brain geometry in COMSOL Multiphysics via an interpolating function. The physical property associated with the grayscale is the diffusivity tensor, assumed here to be isotropic but inhomogeneous. Applications to anti-tumor drug delivery and cancer growth processes are discussed.

One of the most important requirements of any integrated optical technology is the ability to perform optical modulation, which permits to encode a bit stream onto the optical carrier provided by the laser source. In this paper a multiphysics model for silicon modulators adopting a Metal Oxide Semiconductor (MOS) structure is presented.

The aim of the present work is the formulation of a theoretical model describing the transport phenomena involved in a food drying process by a convective oven. The proposed model represents a general and predictive tool capable of describing the real oven’s behavior over a wide range of process and fluid-dynamic conditions. The resulting system of non-linear unsteady-state partial ...

The subject of this work is the design of a LiNbO3 electro-optic tuned Bragg filter to be used as an amplitude modulator. We analyze in detail the realized waveguide and simulate the grating, developing a fabrication methodology for building the Bragg modulator by niobate core etching. Finally, we evaluate the performance of the modulator, using the finite element method analysis.

3D model analysis of the temperature dynamics during a welding process is presented. Bio-heat equation described laser-tissue interaction in porcine and human eyes, simulating the surgery conditions. The modeled behavior of the superficial cornea temperature was compared with direct measurements performed by an infrared thermo-camera. The results indicated a selective, spatially-confined ...

The objective of this paper is to present the results of a numerical study undertaken to investigate the hydrodynamics and turbulent transport and mixing inside two contact tanks, which have the same channels but different location of the baffles. Transient concentration data were used to derive the residence time distribution (RTD) function for both tanks in order to evaluate and compare ...

Transient three-dimensional temperature distribution in a solid, irradiated by a moving Gaussian laser beam, was investigated numerically by means of COMSOL Multiphysics. Convection and radiation from the work-piece surfaces as well as variable thermophysical properties are accounted for.

Mathematical modelling of a catalytic plate reactor for methane steam reforming with COMSOL Multiphysics was carried out. The model reactor includes three channels where methane combustion occurs on the plates bordering the inner side of the outermost channels, whereas methane steam reforming takes place on the plates bordering the central channel.
