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.

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 ...

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.

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 hyporheic zone is defined as an area where water and matter exchange through the sand, gravel, sediments and other permeable soils under and beside streams. Its impact on the hydro-system function is determined by the proportion of subsurface biogeochemical reactions and the fluxes of water exchanging with the hyporheic zone and flowing through the porous sediments. The objective of our ...

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, we introduce a kinetic equation coupled with the Navier-Stokes equations in COMSOL Multiphysics in order to simulate internal structural changes of a flowing complex fluid. Two physical applications are considered, the starting of blood flow in a stenosis and a simulation of a laboratory rheometric set-up. Results show good agreement with the experiments' well known ...

In this paper we propose a finite element model (FEM), to solve the micro-magnetic equations. Two bi-dimensional test problems are treated to estimate the validity and the accuracy of this approach.
