Introduction: The simulation of coupled heat and moisture transfer in constructions is becoming even more important in the last years. COMSOL Multiphysics represents a powerful tool for this kind of simulations as shown in [1,2,3], although applications in this area are still rare. For ... Mehr lesen
Water removal during paper manufacturing is an intensive energy process. The dewatering process generally consists of four stages in which the first three stages, water is removed mechanically through vacuum pulses and pressing.The fourth stage involve thermal drying. The vacuum ... Mehr lesen
Morphogenesis is a tightly regulated process that has been studied for decades. Previously we developed data-based mechanistic models for a range of developmental processes with a view to integrate the available knowledge and to better understand the underlying regulatory logic. In our ... Mehr lesen
Introduction Numerical modeling of melt-casting is becoming a popular tool for the energetic materials and explosives industry. Compared to traditional metal casting, the cooling cycle for explosive melts is significantly longer because of their high Prandtl numbers [1]. Improving the ... Mehr lesen
The bentonite barrier is an essential part of a safe spent fuel repository in granitic bedrock. In this work COMSOL Multiphysics® is used in modelling the Thermal (T), Hydrological (H), Mechanical (M) and Chemical (C) phenomena and processes taking place in a bentonite buffer. Special ...

One viable alternative to non-renewable fossil fuels is the fuel cell. A special class of FC i.e. Proton Exchange Membrane Fuel Cell (PEMFC) has been investigated during the present study. Membrane is a very important part of a PEMFC as most ohmic losses occurs here and limits the ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
