Numerical Analysis of Mass Transfer Rate in Droplet Flow at Microscopic Scales

S. Cito[1], T. Sikanen[1]
[1]Division of Pharmaceutical Chemistry and Technology, Faculty of Pharmacy, University of Helsinki, Helsinki, Finland

Droplet flow at microscopic scale is often used to enhance many pharmaceuticals and industrial processes (i.e. liquid–liquid micro-extraction, nanoparticle synthesis, slow reactions in microfluidic devices, etc.). In all these processes, the mass transfer rate, at the interface between ... Read More

Submarine Gas Hydrate Reservoir Simulations - A Gas/Liquid Fluid Flow Model for Gas Hydrate Containing Sediments

S. Schlüter[1], T. Hennig[1], G. Janicki[1], G. Deerberg[1]
[1]Fraunhofer UMSICHT, Oberhausen, Germany

In the medium term, gas hydrate reservoirs in the subsea sediment are intended as deposits for carbon dioxide (CO2) from fossil fuel consumption. This idea is supported by the fact, that CO2 hydrates are more stable than methane hydrates at certain conditions. The potential of producing ... Read More

Optimization of the Slot Dimensions of a Large Air-gap Linear Synchronous Motor

F. Giacometti[1], C. R. Lines[1], R. J. Cruise[1]
[1]Texchange Limited, London, UK

A COMSOL Multiphysics® model is used to optimise the slot geometry of a large air-gap linear synchronous motor. Fixed dimensions are used for the pole pitch, stator depth, stator width and air-gap, since the amount of available space is usually limited. A parametric sweep of the slot ... Read More

Inclusive Routine of the Soil Surface Energy Balance in COMSOL Multiphysics®

M. Bortoloni[1], M. Bottarelli[2], Y. Su[3]
[1]Department of Engineering, University of Ferrara, Este, Italy
[2]Department of Architecture, University of Ferrara, Este, Italy
[3]Faculty of Engineering, University of Nottingham, Nottingham, UK

In ground-coupled heat pumps (GCHPs) the coupling between heat pumps and ground occurs by means of ground heat exchangers, that can be installed vertically inside boreholes (BHEs) or horizontally (HGHEs). In the horizontal installation, the heat exchangers are placed in shallow trenches ... Read More

Modeling and Simulation of Membrane Contactor Employed to Strip CO2 from Rich Solvents via COMSOL Multiphysics®

N. Ghasem[1], M. Al-Marzouqi[1], N. A. Rahim[1]
[1]United Arab Emirates University, Al-Ain, United Arab Emirates

A mathematical model is developed for the stripping of CO2 from rich solvent. The rich solvent (aqueous NaOH) is used in CO2 absorption from natural gas through gas-liquid hollow fiber membrane contactor. The polyvinylidene fluoride (PVDF) hollow fiber membrane was fabricated via ... Read More

3D Multiphysics Modeling of Bulk High-Temperature Superconductors for Use as Trapped Field Magnets

M. Ainslie[1], J. Zou[1], D. Hu[1], D. Cardwell[1]
[1]Department of Engineering, University of Cambridge, Cambridge, UK

The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of ... Read More

Modeling the ELENA Electron Cooler with COMSOL Multiphysics® Software

G. Tranquille[1]
[1]CERN, Geneva, Switzerland

ELENA is a small cooler decelerator ring at CERN which will be built to increase substantially the number of usable antiprotons delivered to experiments for studies with antihydrogen and antiprotonic nuclei. COMSOL Multiphysics® software has been used to completely model the ELENA ... Read More

Modeling an Adsorption Process in a Shell-and-Tube-Heat-Exchanger-Type Adsorber

G. Salazar Duarte[1], B. Schürer[1], C. Voss[1], D. Bathen[2]
[1]Linde AG, Munich, Germany
[2]Universität Duisburg-Essen, Duisburg, Germany

Pressure Swing Adsorption (PSA) and Temperature Swing Adsorption (TSA) are commonly used for separation/purification of gas mixtures in industrial processes. The cycle time of industrial TSA processes usually ranges from several hours to days. The reason for this long cycle time is the ... Read More

Numerical Investigation of Heat Transfer of Aluminum Metal Foam Subjected to Pulsating Flow

A. Bayomy[1], M. Z. Saghir[1]
[1]Ryerson University, Toronto, ON, Canada

The rapid development of electronic devices leads to more demand for efficient cooling techniques. Porous media represent a convincing passive cooling enhancer due to its large contact surface area to volume ratio and intense mixing of ﬂuid ﬂow. In the present work, numerical studies ... Read More

An Automatic Modeling Approach for Optimized Positioning of an Electrostimulative Implant in the Human Femoral Head

Y. Su[1], D. Kluess[1], W. Mittelmeier[1], M. Ellenrieder[1], U. van Rienen[2], R. Bader[1]
[1]Department of Orthopaedics, University of Rostock, Rostock, Germany
[2]Institute of General Electrical Engineering, University of Rostock, Rostock, Germany

Introduction Electromagnetic stimulation is a common therapy to support bone healing in cases of avascular necrosis or pseudarthrosis. An electrostimulative screw implant (Asnis III s-series screw in Figure 1) is used to stimulate bone regeneration in the treatment of femoral head ... Read More
