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.

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 ...

This paper presents thermo-mechanical and electromagnetic computational results in the time-harmonic and transient domains. This includes the stress analysis induced by the magnetic field and resulting pressure, the Joule heating with skin effects and the corresponding deformation.

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.

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 ...

This paper presents the modeling of high pressure discharge lamps, which are complex molecular systems, using COMSOL Multiphysics. The model accounts for the momentum, mass and energy conservation equations.

This study deals with numerical and experimental investigations of a microwave thawing process. The microwave power generation is calculated from Maxwell’s equations and then from Lambert’s law, using COMSOL Multiphysics. For those two different approaches, the heat source term depends on the dielectric properties of the material. Numerical simulations are compared with experimental ...

Shape Memory Alloys are good candidates for being used as passive dampers, strain sensors, stiffness or shape drivers. In order to develop the use of these alloys in structural vibration control, we present in this paper how to implement a phenomenological model based on the Rl model in COMSOL Multiphysics. We use this implementation to simulate internal loops in order to characterize the ...

Flows in highly heterogeneous media are found in many practical fields, such as hydrology, petroleum engineering, and chemical engineering. The case of two-region heterogeneous media (fractured media, catalytic beds, etc.) plays a fundamental role. The different questions associated to this specific case are illustrated in this paper for two different kinds of transport: (i) flow of a slightly ...
