For this work the multi-objective design environment modeFRONTIER was integrated with COMSOL, bringing the advantages of multi-objective optimization to multiphysics simulations. Practically any commercial analysis tool (such as COMSOL) or in-house code can be integrated within ... En savoir plus

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 ... En savoir plus

This paper describes the use of COMSOL Multiphysics® during the design of a vented box loudspeaker. Templates have been created to model the different needs of a complete design. Based upon those templates a box has been prototyped, measured and confronted to simulation. The cabinet may ... En savoir plus

A successful development of an effective quench detection and protection method for a high temperature superconducting (HTS) coil based on a HTS coated conductor tape lays on a thorough understanding of its slowly propagating, three-dimension (3D) quench behavior. Toward this goal, a 3D ... En savoir plus

This work treats of a preferential oxidation reactor, which is simulated by a two-dimensional axial symmetric model. The reactor serves as purification of hydrocarbon reformat and converts the CO mole fraction from up to 1 % in the feed gas down to a few ppm at the outlet to deliver a ... En savoir plus

There are over 10 million kilometers of pipes and pipelines around the world that carry hazardous fluids and gases. Fluids include oil, oil products, chemicals such as solvents, caustics, acids, corrosives and combustibles often at high pressure and temperature. These pipes are ... En savoir plus

Design of latent heat energy storage systems (LHESS) requires knowledge of heat transfer processes within them, as well as the phase change behavior of the phase change material (PCM) use. COMSOL Multiphysics can be used to model (LHESS). Natural convection plays a crucial role during ... En savoir plus

The method to derive upscaled expressions for the dispersion coefficients for reactive flow in a porous medium uses a periodic unit cell (PUC), which consists for instance of a spherical grain in a cube, but nothing prohibits defining more complex PUC's. Homogenization leads to a coupled ... En savoir plus

The acoustoelastic effect relates the change in the speed of an acoustic wave travelling in a solid, to the pre-stress of the propagation medium. In this work the possibility of assessing nondestructively the stress status in metal sheets, by using the acoustoelastic effect, is ... En savoir plus

Solar drying is a ubiquitous method that has been adopted for many years as a food preservation method. Most of the published articles in the literature provide insight on the performance of solar dryers in service but little information on the dryer construction material selection ... En savoir plus
