Calibration of a Bio-Kinetic Model to Simulate Microalgae Growth new

A. Solimeno[1], J. Garcia[2]
[1]Department of Hydraulic, Maritime and Environmental Engineering, Universitat Politècnica de Catalunya, Barcelona, Spain
[2]Universitat Politecnica de Catalunya, Barcelona, Spain

The aim of present work is to present and calibrate a new mechanistic model that includes physical and biokinetic processes to reproduce the algae growth in photobioreactor or ponds during long-term scenarios. A COMSOL Multiphysics® model is used to implement the microalgae processes ... Read More

Development of a COMSOL Application for the Efficient Evaluation of an Engineered Barrier System

[1] Amphos 21 Consulting S.L., Barcelona, Spain
[2] Swedish Nuclear Fuel and Waste Management Co., Stockholm, Sweden

Radioactive waste repositories include barriers that work to contain the waste, thereby protecting human health and the environment. In deep geological disposal systems, barriers include the natural geological barrier and the engineered barrier system (EBS). The ability of the EBS to ... Read More

Multi-Dimensional Simulation of Flows Inside Mono and Polydisperse Packed Beds

R.G. Schunk [1], J. C. Knox [1], K. Son [1, 2], R. F. Coker [1],
[1] NASA Marshall Space Flight Center, Huntsville, AL, USA
[2] Purdue University, West Lafayette, IN, USA

An analysis to quantify the flow inside the narrow channels of an ISS (International Space Station) CDRA (Carbon Dioxide Removal Assembly) adsorbent bed is presented. The CDRA contains two pelletized adsorbent beds to remove CO2 respired by the crew. Heaters and associated fins inside ... Read More

Generation of Chemical Gradient of Varying Shapes Using Microfluidic Devices

S. Jadhav [1], K. Deekshith [1],
[1] Indian Institute of Technology Bombay, Mumbai, Maharashtra, India

In the work presented, we generated a microfluidic design to obtain different concentration profiles in transverse channels. We also generated another microfluidic design with a flow-fewer zone which we think will help study the cells in a shear free environment. We simulated these ... Read More

Modelagem dos Processos de Descarga em Eletrodos de Baterias de Chumbo-Ácido

P. R. Impinnisi [1], L. F. Siqueira [1],
[1] Instituto Lactec, Curitiba, PR, Brasil

Foi desenvolvido um modelo 3D para simular descargas de eletrodos de baterias de chumbo-ácido. O modelo inclui a formação de filmes isolantes de sulfato de chumbo durante a descarga e permite visualizar a analisar a evolução da distribuição de linhas de corrente, os efeitos de bordas, os ...

[1] Paul Scherrer Institut, Villigen, Switzerland
[2] ETH Zürich, Zürich, Switzerland

Electrochemical flow cells have found widespread use in analytical chemistry due to their short response time, high sensitivity and selectivity. The geometrical flexibility and therefore, the ease of coupling the electrochemical to other experimental techniques has attracted considerable ... Read More

Push or Pull, How Does Silk Flow?

J. Sparkes [1],
[1] University of Sheffield, Sheffield, UK

Silk is one of the longest used and most recognizable textiles that we, as a society, use regularly. We see it as a luxury good, worn as an indicator of success and value. However, despite mankind having domesticated and farmed silkworms for millennia, we still know relatively little ... Read More

Nonlinear Shielded Multipair Twisted Railway Cable Modeling with COMSOL Multiphysics®

Y. Jin [1], G. Papaiz Garbini [1], S. Karoui [1], M. Cucchiaro [1],
[1] SNCF Réseau, Paris, France

Signaling and telecommunication cables are shielded multipair twisted cables that lie along the railway and transfer railway information at low frequency (some kilohertz). Due to the electromagnetic disturbance of the railway environment, coming from high voltage conductors such as the ... Read More

MRI Birdcage RF Coil Resonance with Uncertainty and Relative Error Convergence Rates

J. T. Fong [1],
[1] National Institute of Standards and Technology, Gaithersburg, MD, USA

In a magnetic resonance imaging (MRI) system, it is necessary to excite the nuclei of a patient into coherent precession for imaging. This requires a coupling between the nuclei and a source of radio frequency (RF) power using a transmitter. To receive a meaningful signal, we also need ... Read More
