Fluid-Structure Interaction Model of Active Eustachian Tube Function in Healthy Adult Patients

F. Sheer[1], and S. Ghadiali [1,2]
[1]Mechanical Engineering Department, Lehigh University, Bethlehem, PA, USA
[2]Department of Biomedical Engineering, Ohio State University, Columbus, OH, USA

The Eustachian Tube (ET) is a collapsible tube that connects the middle ear to the nasopharynx. Dysfunction in the ET leads to a disease called Otitis Media. Our goal is to develop and use fluid-structure interaction (FSI) models of ET opening phenomena to better understand what factors ... Read More

Development of a Mathematical Model for an Anode Baking Process with COMSOL Multiphysics®

P. Nakate [1], D. Lahaye [1], C. Vuik [1], M. Talice [2],
[1] Delft University of Technology, Netherlands
[2] PM2 Engineering, Italy

The anode baking process has gained significant attention since the 1980s due to its importance in Aluminium industry. A good anode baking process strives to achieve multiple goals including reduction of NOx from emissions. NOx generation is mainly due to the high-temperature ... Read More

Optimizing Bio-Inspired Flow Channel Design on Bipolar Plates of PEM Fuel Cells

X. Wang[1], J. Peitzmeier [2], and S. Kapturowski[3]
[1]Oakland University, Rochester, MI, USA
[2]Michigan Technological University, Houghton, MI, USA
[3]The State University of New York at Buffalo, Buffalo, NY, USA

The flow channel design on bipolar plates affects proton exchange membrane (PEM) fuel cell performance by influencing reactant distribution and water removal in an operating fuel cell. The fuel cell performance can be improved by varying the type, size, or arrangement of channels. Two ... Read More

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 ... Read More

Pore-Level Influence of Contact Angle on Fluid Displacements in Porous Media

H. Ali Akhlaghi Amiri[1]
[1]University of Stavanger, Stavanger, Norway

Wettability affects two-phase displacements in porous media by determining the microscopic distribution of fluids in pore spaces. The impact of wettability on transport properties at macro-scales has been widely addressed in literature; however a deeper understanding of wettability ... Read More

Two-Dimensional Numerical Simulation of a Planar Radio-Frequency Atmospheric Pressure Plasma Source

L. Wang [1], G. Dinescu [2], E.- R. Ionita [2], C. Leys [1], A. Y. Nikiforov [1],
[1] Department of Applied Physics, Ghent University, Ghent, Belgium
[2] National Institute of Laser, Plasma and Radiation, Măgurele, Romania

The radio-frequency(RF) plasma sources have shown great potential in various industrial applications such as thin coatings deposition and polymers modification[1,2]. Physics of low pressure RF plasmas has been investigated significantly[3]; however, this kind of plasma source is rarely ... Read More

Using Temperature Signals to Estimate Geometry Parameters in Fractured Geothermal Reservoirs

F. Maier[1], P. Oberdorfer[1], I. Kocabas[2], I. Ghergut[1], M. Sauter[1]
[1]Dpt. Applied Geology, Center of Geosciences, Georg-August-University, Göttingen, Germany
[2]Petroleum and Natural Gas Engineering Department Batman, Batman University, Batman, Turkey

We compare the output of 2D single fracture models as well as analytical solutions of the problem. The temperature signal is evaluated with the heat transfer mode while the flow field is assumed to exhibit Darcy flow everywhere. The problem is time-dependent so we have to take into ... Read More

Propagation Of Tsunamis Over Large Areas Using COMSOL

C. Cecioni, and G. Bellotti
University of Roma TRE, DSIC, Rome, Italy

This paper presents a numerical model based on the mild-slope equation (MSE for short) solved using the PDE mode of the software COMSOL Multiphysics suitable to reproduce the propagation of small amplitude tsunamis in the off-shore field. The model solves the governing equations in the ... Read More

Magnetic Fields and Materials for Medical Bone Reconstruction Assisted by Advanced Finite-Element Simulations

A. Sytcheva[1] and T. Herrmannsdörfer[1]
[1]Hochfeld-Magnetlabor Dresden, Forschungszentrum Dresden-Rossendorf, Dresden, Germany

We address the use of magnetic fields, forces, and materials for medical purposes. In particular, the treatment of osteochondral lesions is aimed for. To support ongoing activities in this field of research, last advances in using Finite Element Analysis (FEA) for the simulation of ... Read More

Ignition Process of Microplasmas

H. Porteanu, and R. Gesche
Ferdinand-Braun-Institut für Höchstfrequenztechnik, Berlin, Germany

Microplasmas at atmospheric pressure are required in many applications, where treatments in normal ambient, with spatial resolution, are important. The interest on such miniaturized sources has increased due to the availability of a new generation of microwave sources based on high power ... Read More
