Simulation of Pumping Induced Groundwater Flow in Unconfined Aquifer Using Arbitrary Lagrangian-Eulerian Method
A novel numerical method characterizing groundwater flow in unconfined aquifer is demonstrated. In contrast to the conventional method (Dupuit approach considering horizontal flow only), hydraulic head is simulated in horizontal and vertical directions. The new approach is introduced via ...

Highly Concentrated Solar Radiation Measurement by Means of an Inverse Method
This work focuses on the numerical analysis conducted on the prototype sensor for the measurement of highly concentrated radiative heat fluxes, based on an inverse heat transfer method, realized at the ENEA Portici Research Center in collaboration with the DETEC department of the ... En savoir plus
Using COMSOL for Optimal Design of Engineering Barriers of Nuclear Waste Repositories
The Swedish Nuclear Fuel and Waste Management Co (SKB) is responsible for final disposal of spent fuel and radioactive waste. SKB operates SFR, an underground waste repository in crystalline rock. The evolution of groundwater flow within the repository needs to be estimated considering ... En savoir plus
Numerical Simulation of Warm-Air Drying of Mexican Softwood (Pinus Pseudostrobus)
In this work, the numerical simulation of Mexican softwood (Pinus pesudostrobus) drying is presented by solving a physics-based model. The model was developed by considering the heat and mass transport and the representative elementary volume, which involves the solid, liquid and gas ... 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
Optimization of Thermal Properties Identification of Complex Thin Films Using MATLAB® and COMSOL Multiphysics
The importance of laser processing and thermal properties investigation of bulk materials and thin layers is still increasing. For thermal properties investigation many experimental systems were developed based on the photothermal effect. One of typical ways is to induce a rapid surface ... En savoir plus
Simulation Organogenesis in COMSOL: Deforming and Interacting Domains
Organogenesis is a tightly regulated process that has been studied experimentally for decades. We are developing mechanistic models for the morphogenesis of limbs, lungs, and kidneys with a view to integrate available knowledge and to better understand the underlying regulatory logic. ...

The Refinement of the Contact Compression Ring Chamfer for Race Engine Conditions
Use of COMSOL Multiphysics: In operation, the piston ring is surrounded by gas acting on it, using effect of chamfer design has been considered using Love’s equation in conjunction with Stone’s equation for force ad Miler’s equation for gas pressure modelling. The chamfer geometry was ... En savoir plus
Ammonia Removal From Water by a Liquid-Liquid Membrane Contactor Under a Closed Loop Regime
Ammonia separation from water by membrane contactor was simulated on transient state and compared with experimental data. Aqueous low concentrated solution of ammonium with high pH has been pumped inside the hydrophobic hollow fibers, acid solution in the outside part. The system is in ... En savoir plus
Battery Pack Temperature Distribution Simulation with COMSOL and MATLAB®
This work is to present an implementation of COMSOL with MATLAB® [1] for the liquid cooling system of a battery pack based on the physics in COMSOL. The m.file of a model of battery module from COMSOL 4.2 is exported and modified to run in MATLAB®, as well as is managed by using another ... En savoir plus
