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 ...

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 ...

A numerical analysis of the conjugate optical-thermal fields in an amorphous silicon thin film deposited on a glass substrate and irradiated by a moving Gaussian laser source is carried out. The combined optical and thermal models are solved by means of COMSOL Multiphysics. Results are given for continuous and pulsed moving Gaussian heat sources and they are presented as temperature ...

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.

Politecnico di Milano
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 ...
