Comparison Between Turbulent and Laminar Bubbly-Flow for Modeling H2/H2O Separation
One of the most critical aspects on water electrolysis is gas-liquid separation, especially in systems with forced convection. The main problem of this kind of circulation is that a gas fraction could return to the electrolysis circuit. A suitable design of separator devices could be a ... En savoir plus
3D Modeling of Fracture Flow in Core Samples Using ?-CT Data
Knowledge on flow behavior in fractured reservoir rocks is of great interest in petroleum engineering as well as for geothermal assets. Due to the big difference of magnitude (fracture aperture: ~?m, lateral extension of reservoirs ~km), modeling of discrete fracture flow is not ... En savoir plus
3D Simulation of Air-Glass Heat Exchange in a Set of Vials
In this model a three-dimensional heat transfer analysis was performed by using COMSOL Multiphysics\' Heat Transfer Module. The model is about the heating of a set of vials (Figure 1) in a current of hot air in the laminar regime. We used time dependent studies to predict the thermal ... En savoir plus
Modeling Pit Lake Flooding After Mine Closure
Most of mining works, either on the surface or in the underground, demand continuous groundwater pumping in order to operate under dry conditions. When the mining activity stops, dewatering also stops and mining facilities begin to flood, quite quickly at the beginning but becoming ... En savoir plus
Deposition of Submicron Charged Spherical Particles in the Trachea of the Human Airways
This paper presents a numerical study of the deposition of submicron charged spherical particles caused by convection, Brownian and turbulent diffusion in a pipe with a smooth wall and with a cartilaginous ring wall structure (see figure). The model is supposed to describe deposition of ... En savoir plus
Numerical Modeling and Performance Optimization Study of a Diaphragm Pump for Medical Application
In this contribution we present the results of the numerical modeling and performance optimization study of a diaphragm pump for drug infusion. The main objective is to develop a numerical model that replicates the pumping cycle (400ms) and also provides indications about the variation ... En savoir plus
Building Energy Simulation Using the Finite Element Method
In order to predict, improve and meet a certain set of performance requirements related to the indoor climate of buildings and the associated energy demand, building energy simulation (BES) tools are indispensable. Due to the rapid development of FEM software and the Multiphysics ... En savoir plus
A Multiphysics Approach to the Modeling of Biological Prosthetic Heart Valves
The complex behavior of biological prosthetic heart valves was simulated. A multiphysics computational approach was adopted using different modules of COMSOL Multiphysics: the LiveLink(TM) interface was used to exchange the valve geometry with CAD, Structural Mechanics Module to set ...

Numerical Investigation of Non-Newtonian Laminar Flow in a Curved Tube with Insert
Non-Newtonian laminar flows in curved circular tubes with inserts are investigated by computer simulations. 0.65% solution of NaCMC is considered. Three-dimensional incompressible Navier-Stokes equations are solved using COMSOL Multiphysics. Placements of inserts inside the curved tubes ... En savoir plus
Thermal and Fluid Dynamics Studies Applied to Steel Industry
The energy pay back is one of the most interesting field especially in the steel industry where this contribution is strictly connected to steams and emissions inside and outside the plant. Perhaps, this application is sometimes disturbed by a strong variation of emissions (\"off gas\"). ... En savoir plus
