[1] Volkswagen AG, Wolfsburg, Germany
[2] Institute of Engineering Thermodynamics, German Aerospace Center (DLR), Stuttgart, Germany; Helmholtz Institute Ulm for Electrochemical Energy Storage (HIU), Ulm, Germany; Institute of Electrochemistry, University of Ulm, Ulm, Germany

Due to the rapid growth of the electromobility market much effort currently is being put into investigating electric vehicle batteries. Optimizing the microstructure of the cell components is playing an important role in extending range, enhancing fast charging capabilities and reducing ... En savoir plus

Mechanical Damage Models for Concrete

M. Laviña [1], A. Idiart [1],
[1] Amphos 21 Consulting S.L., Barcelona, Spain

Damage models can be used to simulate the quasi-brittle behaviour of cementitious materials, since they can represent cracking in a smeared-way under various loading conditions. COMSOL Multiphysics® developed a functionality to access external material models for structural mechanics in ... En savoir plus

Thermo-fluid Dynamics Modelling of Hydrogen Absorption and Desorption in a LaNi_4.8Al_0.2 Hydride Bed

D. Baldissin[1] and D. Lombardo[1]
[1]Compumat S.r.l., Torino, Italy

A two-dimensional mathematical model for the absorption and desorption of H2 in LaNi4.8Al0.2 was developed and experimentally validated. The model is composed of an energy balance, a mass balance and a momentum balance. These differential equations are numerically solved by means of the ... En savoir plus

Numerical and Experimental Investigation of Natural Convection Flow of (Sub-) and (Super-) Critical CO2 in Aqueous Phase

R. Khosrokhavar[1], G. Elsinga[1], R. Farajzadeh[2], H. Bruining[1]
[1]Delft University of Technology, Delft, The Netherland
[2]Shell International Global Solutions, Amsterdam, The Netherland

Optimal storage of carbon dioxide (CO2) in aquifers requires dissolution in the aqueous phase. Transfer of CO2 from the gas phase to the aqueous phase or oil phase would be slow if it were only driven by diffusion. Dissolution of CO2 in brine (oil) forms a mixture that is denser than the ...

Numerical Prototyping of Locally Heated Digital Microfluidic Devices

C. Ozen [1], G. Sathyanarayanan [1], S. Cito [2], T. Sikanen [1],
[1] Faculty of Pharmacy, Drug Research Programme, University of Helsinki, Helsinki, Finland
[2] Department of Mechanical Engineering, Rovira i Virgili University, Tarragona, Spain

An alternative approach to integration of a local heat source with the digital microfluidic (DMF) platform by attaching inkjet-printed silver microheaters to the bottom plate was recently introduced (Sathyanarayanan et al., MNE 2017). This approach allows more degrees of freedom to the ... En savoir plus

Numerical Study of Heat Transfer Effect of Wire EDM on P91, SS304, Al 1050 using COMSOL Multiphysics®

Aquifer Pumping Test Evaluation: 1D Classical vs. 2D Numerical Solutions

E. Holzbecher¹
¹German University of Technology in Oman

In a pumping test the drawdown of the water table in a piezometer is recorded, as response to pumping from a nearby well. Pumping tests belong into the common toolbox of hydro-geologists, used to obtain basic parameters for aquifer characterization. There are various approaches to ... En savoir plus
