Chromatographic Separation of Tröger’s Base in a Batch Column

A. Fayolas [1], M.G. Sanku[1], M. Pascoa[1], M. Xynou[1]
[1]KTH Royal Institute of Technology, Stockholm, Sweden

The objective of the study is to investigate the chiral separation of Tröger’s base enantiomers using batch chromatography. Because of its resolution, chromatography is often the preferred method for chiral separations. The separation of Tröger’s base is resolved by using the COMSOL ... Read More

Adaptive Numerical Simulation of Streamer Propagation in Atmospheric Air

S. Singh[1], Y. Sedyuk[1], R. Summer[2]
[1]Chalmers University of Technology, High Voltage Engineering, Gothenburg, Sweden
[2]Schneider Electric, Regensburg, Germany

Simulations of streamer discharge was performed by utilizing a space adaptive numerical scheme based on logarithmic representation of mass conservation equations, which governs the transport of charge carriers. Implementation of a model, which describes the propagation of a streamer in ... Read More

Virtual Prototyping of a Microwave Fin Line Power Spatial Combiner Amplifier

A. Leggieri[1], F. Di Paolo[1], D. Passi[1]
[1]University of Rome "Tor Vergata" - Department of Electronic Engineering, Rome, Italy

This paper describes the Virtual Prototyping based on a COMSOL Multiphysics® simulation for a novel Microwave Fin Taper (FT) Spatial Power Combiner (SPC) Amplifier. The analyzed system is waveguide (WG) based, and uses FT Probes to convert the energy of a rectangular WG EM fundamental ... Read More

The Use of COMSOL Multiphysics® for Studying the Fracture Pressure of Rectangular Micro-Channels Embedded in Thin Silicon Substrates

K. Howell[1], H. Georgiou[2], P. Petagna[3], G. Romagnoli[3]
[1]George Mason University, Fairfax, VA, USA
[2]Cyprus University of Technology (C.U.T), Limassol, Cyprus, EU
[3]CERN - The European Organization for Nuclear Research, Geneva, Switzerland, EU

The thermal management of silicon detectors and related electronics through micro-structured silicon cooling plates is gaining considerable attention for high precision particle trackers. Micro-fluidic circuits are etched in a silicon wafer, which is then bonded to a second wafer to ... Read More

Simulation of the Coalescence and Subsequent Mixing of Inkjet Printed Droplets

M.H.A. van Dongen[1], H.J. van Halewijn[2]
[1]Fontys University of Applied Sciences, Expertise Centre Thin Films & Functional Materials, Eindhoven, The Netherlands
[2]Fontys University of Applied Sciences, Eindhoven, The Netherlands

Coalescence of droplets is a widely investigated phenomenon. In inkjet printing micrometer sized droplets are deposited on a substrate which when positioned close enough to each other will coalesce and mix. Little is known about the flows and mixing behaviour within these small droplets. ... Read More

Simulation of a 3D Flow-Focusing Capillary-Based Droplet Generator

D. Conchouso[1], E. Al Rawashdeh[1], A. Arevalo[1], D. Castro[1], I.G. Foulds[1]
[1]King Abdullah University of Science and Technology, Thuwal, Saudi Arabia

This paper presents the multiphase 2D axisymmetric simulation of a three-dimensional flow-focusing microfluidic droplet generator using the laminar two phase flow, phase field interface in COMSOL Multiphysics®. The performance of the device is characterized at different flow conditions. ... Read More

Self-Consistent Modeling of Thin Conducting Wires and Their Interaction with the Surrounding Electromagnetic Field

G. Eriksson[1]
[1]ABB AB, Corporate Research, Västerås, Sweden

It is demonstrated how the RF Module of COMSOL Multiphysics® can be used to approximately model thin conducting wires or cables and how they interact with a surrounding electromagnetic field. Despite being non-stringent the method can reasonably well predict currents induced by an ... Read More

Reactive Transport and Convective Mixing During CO2 Migration in a Saline Aquifer

E. Abarca[1], A. Nardi[1], F. Grandia[1], J. Molinero[1]
[1]Amphos21 Consulting, Barcelona, Spain

The capture and storage of CO2 in deep geological formations is one of the proposed solutions to reduce CO2 emissions to the atmosphere. CO2 is injected as a supercritical fluid deep below a confining geological formation that prevents its return to the atmosphere. A configuration of ... Read More

Oscillatory Thermal Response Test (OTRT) – An Advanced Method for Gaining Thermal Properties of the Subsurface

P. Oberdorfer[1]
[1]Georg-August-Universität Göttingen, Göttingen, Germany

Thermal Response Tests (TRTs) are the state-of-the-art method to obtain the thermal conductivity of the subsurface in the nearby ambience of a borehole heat exchanger (BHE). The results of TRTs are used to determine the necessary depth of the borehole and to make long time predictions ... Read More

Turbulent Premixed Combustion with FGM in COMSOL Multiphysics®

R. Bastiaans[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

In this paper a new method for turbulent combustion modeling is introduced in COMSOL Multiphysics®. The method is called Flamelet Generated Manifolds (FGM). The method is based on the concept of flamelets, elemental reaction layers in combustion. The only hypothesis is that the turbulent ... Read More
