Thermoplastic polymers are frequently used in several industries, and represent the most important group of polymeric materials. During the injection moulding process, the cooling phase including solidification is often the most significant part of the manufacturing cycle. In this paper we study the coupling phenomena between the crystallization and the thermal kinetics in the polymer ...

In this work, we present the modeling of V-shaped silicon micro-cantilevers. The sensitivity of different V-shaped silicon cantilevers is estimated, as a function of the geometrical dimensions of the cantilever.

Solid extruded polymeric materials such as crosslinked polyethylene are widely used in the electrical insulation of underground high voltage power transmission cables. This paper treats the combined effect of space charge and cavities, on the electric field, and potential and temperature distribution within the insulation. The model is a 3D stationary linear COMSOL Multiphysics model and the ...

In this paper, different approaches for modeling heat transfer in materials are examined: Heat anisotropy in styreneacrylonitrile copolymer provided by the nanodispersion and the orientation of single wall carbon nanotubes Heat protection of aluminum plate using nonwoven material made with high performance fibers Fire protection using intumescent paint on steel plate. It is shown that ...

Our work is to improve the surface texturing process by laser irradiation. In this study, thermal modelling of the laser-matter interaction for a single laser impact case is presented. A 1D modelling was carried out. The purpose was to determine the dimension of the liquid layer and the ablated matter volume. The model accounts for the evolution of material thermodynamic properties, the ...

The most common case of crevice corrosion occurs on passive materials such as stainless steels, in oxidizing-chloride environments. A flexible crevice propagation model has been developed to allow parametric studies of the solution. Our main results allow us to establish diagrams of stability of solid and gas phases within the crevice and to evaluate the influence of the external ...

In this paper we use the COMSOL Heat Transfer Module to simulate the radiative and conductive heat transfer in an experimental oven fitted with electrical infrared emitters. In particular, we study paint curing temperature and compare our results to experimental data.
