Iterative Learning Control for Spatio-Temporal Repetitive Processes

D. Kowalów [1], M. Patan [1]
[1] Institute of Control & Computation Engineering, Zielona Góra, Poland

Recently, due to the dynamically increasing complexity of modern systems, a strong necessity appears for more systematic approaches to high quality control and process monitoring. Requirements imposed by process control in the area of spatio-temporal physical systems also called ... 詳細を見る

Hydrodynamics and Mass Transfer in Taylor Flow

F. L. Durán Martínez [1], A. M. Billet [1], C. Julcour-Lebigue [1], F. Larachi [2],
[1] Toulouse University, Toulouse, France
[2] Laval University, Quebec, Canada

In the present work, numerical simulations of a Monolith Reactor (MR) are carried out in order to develop a pre-design tool for industrial-scale reactors applied to highly exothermal reactions. The reacting circular channels (2-4 mm internal diameter) are coated with a few micron thick ... 詳細を見る

COMSOL Multiphysics® Simulation of the Electrokinetic Effect in Gidrogeology

M. A. Narbut [1], K. V. Titov [1], P. K. Konosavsky [1],
[1] Saint Petersburg State University, Saint Petersburg, Russia

The groundwater flow is accompanied by the electric field with potential called usually the streaming potential or the Self-Potential (SP) to be measured on the ground surface (e.g., Rizzo et al., 2004; Bolève et al., 2007; Jardani et al., 2009). We studied numerically the SP signals ... 詳細を見る

It is well-known that metal nanoparticles (NPs) excited at the plasmon frequency not only exhibit peculiar optical properties (e.g., a peak in the extinction spectrum, an enhanced electromagnetic near-filed) but also heat up [1]. This phenomenon is highly investigated for medical ... 詳細を見る

Design and Implementation of a Small UAV’s Pod Equipped with a Solid Oxide Fuel Cell

N. Briguglio [1], G. Giacoppo [1], O. Barbera [1], F. Cipiti [1], M. Ferraro [1], G. Brunaccini [1], L. Di Giovanni [1], N. Randazzo [1], E. Antonucci [1]
[1] CNR ITAE, Italy

Unmanned aerial vehicles (UAVs) have recently received great interest due to their great potential in both military and civil applications [1-4]. Testing and construction of UAVs is expensive and time consuming and a simulation approach can help to reduce cost for both design and tests. ... 詳細を見る

Investigation of Ion Interactions and Space Charge Effects in a Time of Flight Ion Trap Resonator

[1] CSEM SA, Neuchatel, Switzerland
[2] CSEM SA, Alpnach, Switzerland
[3] CSEM SA, Landquart, Switzerland

An ion trap resonator, used for mass spectrometry, is investigated. Simulations are used to define the stabilization criterion of ion trajectories by optimization of the electrode configurations. The ion interactions are investigated and shown to help in reduction of ion-diffusion. Space ... 詳細を見る

Argon Plasma Simulations for Educational Purposes at Fontys University of Applied Physics

H. van Halewijn [1],
[1] Fontys University of Applied Physics, The Netherlands

At the Fontys University of Applied Physics (The Netherlands) a plasma etcher has been acquired for educational purposes. The machine operates at low power up to 30 Watt and is driven with a magnetic coil at 13.56 MHz. The use of COMSOL Multiphysics software will be discussed to simulate ... 詳細を見る

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 ... 詳細を見る

Diverse Models for Graphite Brick Deformation and Stress State in UK AGR Nuclear Reactors

J. Burrow [1], A. Bond [1],
[1] Quintessa Ltd, United Kingdom

The UK Advanced Gas-cooled Reactor fleet, operated by EDF Energy, utilize a graphite core consisting of a lattice of around 3000 annular bricks. Due to irradiation, oxidation and thermal effects, the bricks deform and loose mass as they age. Of key concern is the late-life behavior of ... 詳細を見る

A COMSOL-based 2D Self-Consistent Microwave Plasma Model

A. Berthelot [1], A. Bogaerts [1],
[1] PLASMANT Group, University of Antwerp, Belgium

In this paper, we present a 2D axisymmetric self-consistent plasma fluid model for microwave plasmas operating in argon. The model was developed using COMSOL Multiphysics and its Plasma Module. Plasma, flow, heat and electromagnetic equations solved self-consistently. The effect of the ... 詳細を見る
