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 ...

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.

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.

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 ...

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.

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.

In this paper we study the natural convection for Dual In-Line Memory Module (DIMM) systems. Numerical models are developed using COMSOL Multiphysics. The results, obtained for imposed ambient temperature and operative conditions (power supplied to the CPUs) were produced and complex fluid motion field could be detected.

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 ...

This research presents a model describing the behavior of fluids during a septic filling processes. Numerical simulations were performed to investigate the laminar flow and rheological behavior of shear thinning and Newtonian fluids in 3-dimensional steady state and time-dependent configurations. The mass and momentum balance equations were solved with the finite element method using ...

The paper presents a two-dimensional model to describe the gas flow in a propane autothermal reactor, developed at the CNR-ITAE Institute, and aimed to design a Beta 5 kWe hydrogen generator, named HYGen II, to be used with Polymer Electrolyte Fuel Cells (PEFCs) for residential applications. The main aim of the mathematical model was to optimize the reactor geometrical key parameters (diameter ...
