This paper presents a 3D numerical model to predict the whole process of coaxial powder flow, including the particle stream flow in and below the nozzle and also the laser-particle interaction process. The Particle Tracing Module of COMSOL Multiphysics is used to solve the coupled ... Per saperne di più
For a better understanding of phenomena associated to the appearance of defects in laser welding, a heat and fluid flow model is developed. This study is focused on the modeling of a static laser shot on a sample of steel. This 2D axialsymmetric configuration is used to study phenomena ... Per saperne di più
A mathematical model is developed to determine the weight loss and the freezing rate during the freezing of unwrapped foodstuffs. The model allows comparing two freezing processes; the first uses nitrogen gas at -80°C and the second uses cold air. The model includes thermophysical ... Per saperne di più
In this study, COMSOL®4.2a is used to model a microwave heating process in a TE10 rectangular waveguide. The sample consists of a small cylindrical Ca-alginate gel (D = 8 mm, H = 10 mm) inoculated with bacteria Escherichia Coli K12. The sample is placed along the microwave propagation ...

Windows are the thermal weakest places in the external envelop of buildings. This is true for historic windows with original single pane glazing in historic buildings. To reduce the energy consumption and to improve thermal comfort of historic buildings, replacing these windows by modern ... Per saperne di più
This study deals with a numerical investigation of the melting process of a PCM in a rectangular enclosure differentially heated. COMSOL Multiphysics is used in order to numerically solve Navier-Stokes and energy equations in the considered system. Adopting an enthalpy formulation, one ... Per saperne di più
A conjugate conductive-convective-radiative discrete model useful for the study and the simulation of heat transfer in a ceramic or metallic foam is presented. A Generation-based Technique is used for the foam representation, using the Weaire-Phelan structure and heat transfer is studied ... Per saperne di più
The job of designing end-winding corona protection (ECP) system is one of the very important and complex phases for insulation configuration of high voltage rotating machines. This complexity stems on one hand from the highly nonlinear characteristics of the ECP material and on the other ... Per saperne di più
A hybrid technique based on the use of the FEM and the transfer matrix method is used to identify the frequencies at which thermoacoustic instabilities are expected and the growth rate of the pressure oscillations at the onset of instability. The Helmholtz equation is used to model the ... Per saperne di più
This paper will describe some applications of COMSOL Multiphysics to the analysis of Frequency Selective Surface (FSS) structures. Particular attention will be devoted to the possibility of designing a stealthy antenna using the FSS structure. In fact, since it possesses a dual filter ... Per saperne di più
