This paper reports on progress in the implementation of COMSOL Multiphysics 3.2 to model thermal stresses in a three-dimensional solidifying shell, as occurs typically in the industrial continuous casting of copper, copper alloys and steel. Computer memory requirements prohibit a direct 3D numerical simulation of the temperature and the stresses. Instead, we use the fact that casting ...

The model for study of thermal mechanical behavior of multilayer thin films was developed. The stress-strain analysis was carried out in combination with thermal effects. The 2D thinfilm model has been solved by FEMLAB 3.1i. The middle layer was thermally loaded with Ohmic heating and other layer’s thicknesses were varied in time. All material data like elastic coefficients, thermal ...

Development of new handling microsystems needs integration of field effect thin film transistors made directly on various low temperature substrates, as glass for example, with other functions. Argon laser is used to melt completely and then to crystallize 400 nm thick amorphous silicon films. However, the implementation of this process generates cracking and destruction of the silicon thin film ...

Self-reheating tins are composed of two parts; one of them contains a ready-to-eat preserved product, the other one, the components of an exothermic process which, once started, brings the edible product to the temperature at which it is usually eaten. Some existing data on the temperatures in the heating and heated parts during the process have been used to validate the results obtained by ...

Heat transfer is simulated on a gas sensor component and its closest surroundings consisting of a carrier and bond wires mounted on a printed circuit board. The component is heated in order to improve the performance of the gas sensing element. Power dissipation occurs by all three modes of heat transfer; conduction from the component through bond wires and carrier to the printed circuit board as ...

FEMLAB was used to aid in the design of a novel temperature management system. The system under consideration is a heat sink consisting of a carbon foam block brazed to the inside of an aluminum enclosure. The high thermal conductivity carbon foam is structurally reinforced and filled with a phase change material. A phase change material (PCM) is a substance which releases a large amount of ...
Roctool is a company which develops and sells some process to heat and transform composite materials very quickly. One of these, the Cage System®, uses an inductive heating process which heats instantaneously the tooling surface of the mold, where the composite we want to transform is put. The thermal diffusion in the mass mold is reduced relative to other means of heating.

The electrophotographic print process uses polymer toner particles to create the desired print image on the paper. After depositing the particles on the paper, the particle layer has to be heated beyond the glass point of the polymer to create a homogeneous layer. This fusing process is one of the most energy-consuming parts of the whole print process. It is therefore imperative to limit the ...

The aim of this work is to optimize the efficiency of an intumescent coating that is designed to protect steel in a hydrocarbon fire. This kind of coating, applied on steel plate, is usually evaluated in big industrial furnaces and exposed to hydrocarbon fire conditions. FEMLAB has been first used to model heat transfers in the virgin steel plate: a three dimensional model has been created using ...

In this paper, we validate a numerical model of a “V”-shaped buckle-beam electro-thermal actuator through FEMLAB simulation. The motivation here is similar to that of the simulation of purely electronic VLSI circuits: before manufacturing a prototype, one wishes to virtually build the device and predict its behavior. FEMLAB allowed us to study the effect of temperature dependant ...
