In order to improve the design of an induction furnace and to optimize the charge melting, a COMSOL Multiphysics® application is developed. This application runs a furnace model. The inductor, supplied with an alternative electrical tension, creates a variable induction field B ⃗. Due to ... En savoir plus
Currently in the semiconductor industry more than 80% of silicon crystal are grown by the Czochralski (Cz) method. In this method, fused silica (SiO2) crucibles and graphite heaters are used inside furnaces. The surface of the crucibles, which are in contact with the molten silicon, is ... En savoir plus
Laser cladding is an additive manufacturing process, where a laser beam creates a melt pool, into which powder is fed from a powder nozzle. Due to the feed motion of the laser beam and the powder nozzle relative to the workpiece, coatings and 3D parts can be deposited, which consist of ... En savoir plus
The heat and fluid flow calculation inside the melt pool in welding processes is a complex challenge. It can be useful to predict defects in the weld seam or to study the influence of some process parameters. Even if the required equations are mastered over the last few years, the cost ...

Laser metal deposition is widely adopted for coating, reparation and 3D printing. Using COMSOL, we have developed a numerical model with full coupling of laminar fluid flow and heat transfer. The Marangoni effect is considered to capture the enhanced convective heat transfer as well as ... En savoir plus
An auto-consistent multiphysical 3D model with strong coupling between Heat Transfer, Navier Stokes and ALE problems is proposed for the description of transient development of the keyhole and the melted zone in laser welding of metallic materials. It showed a satisfactory correspondence ... En savoir plus
Many materials require functionally graded cellular microstructures whose porosity is engineered to meet specific requirements of diverse applications. It has been shown in previous work that the bubble growth rate of a polymeric foam can be influenced by the surrounding acoustic ... En savoir plus
Selective Laser Melting (SLM), like many other additive manufacturing techniques, offers flexibility in design expected to become a disruption to the manufacturing industry. The current cost of SLM process does not favor a try-and-error way of research; which gives more room for ... En savoir plus
In order to optimize the industrial “ammunition cooling” process, a COMSOL Multiphysics® model is proposed. A shell body filled with a melt-cast explosive formulation is poured and cooled by circulation of a heat transfer fluid. The solidification of the explosive composition has several ... En savoir plus
Current research focus on improvement of electrical, mechanical, surface characteristics of polypropylene films by incorporation of nanoparticles into the polymer matrix of the film. We built 3D model of polypropylene Nanocomposites made of polypropylene matrix and incorporating various ... En savoir plus
