Heat and mass transfer can be analyzed for conditions that may limit shelf-life. With this target, the purpose of the present work is the development of a general model which is applicable to a large variety of packaging configurations, food products and environmental conditions. To this end, COMSOL Multiphysics is exploited in a full 3D geometry.

In the present paper we report the results obtained applying COMSOL Multiphysics to the numerical simulation of Cyclic Voltammetries (CV’s) at microelecrodes arrays. CV’s at inlaid micro disk electrode arrays have been simulated showing how the electrochemical response is affected by geometrical parameters such as the electrode radius and the distance among the electrode canters.

Buffer chemical polishing is a cheap, simple and effective processing technique for single grain high gradient and polycrystalline lower gradient cavities. This paper describes the thermal-fluid finite element model adopted to simulate the process, the experimental flow visualization tests performed to verify the simulation and a novel device fabricated to solve the problem.

In this communication, we deal with the numerical simulation of Voltage Operated ionic Channels (VOC) in Bio-Electronics. Suitable functional iteration techniques for problem decoupling and finite element methods for discretization are proposed and discussed. Model and computational procedures are validated in the simulation of a real-life VOC under several working conditions.

An efficient simulation of the inverse extrusion process has been performed through the coupling of three modules in COMSOL Multiphysics: fluid-dynamics, general heat transfer and ALE. The strain, the strain rate, and the stress field can be completely defined after the complete definition of the velocity field of the material under the action of the tool. The definition of the stresses and of ...

The main object of this paper is the determination of the impulse response, in the low frequency range, for calculating the reverberation time and the energetic parameters in this space. An absorbing material is modelled by using the propagation of sound waves in an equivalent fluid. The results of this Finite Element model are compared with experimental measurements of impulse responses ...

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 ...

This paper describes an example of full fluid structure interaction. The 2D dynamics of a box-type pile-anchored floating breakwater is solved by means of two models using COMSOL Multiphysics . Simulated wave transmission and vertical displacements of the floating breakwater agree well with physical model results.
