A numerical analysis on transient three-dimensional temperature distribution in a semi-infinite solid, irradiated by a moving Gaussian laser beam, is carried out numerically by means of the code COMSOL Multiphysics. The investigated workpiece is simply a solid. A laser source is ... En savoir plus

Numerical and Experimental Analysis of Natural and Mixed Convection Heat Transfer for Vertically Arranged DIMM

G. Petrone, and G. Cammarata
University of Catania, Catania, Italy

It is commonly recognized that careful thermal design of electronic equipments represents an unavoidable pre-production step in order to ensure reliability and performance of those components during their functioning. This paper mainly concerns a comparison between experimental and ... En savoir plus

Thermal and Material Flow Modelling of Friction Stir Welding Using COMSOL

H. Schmidt[1,2], and J. Hattel[1]
[1]Technical University of Denmark, Kgs. Lyngby, Denmark
[2]HBS Engineering, Frederiksberg, Denmark

Two friction stir welding models are presented – a global thermal model using the temperature dependent heat source and a local material flow and heat generation model allowing for detailed investigation of different contact conditions. The two models are coupled into a larger local ... En savoir plus

Modeling the Thermally Induced Curvature of Multilayer Coatings with COMSOL Multiphysics^TM
