Numerical Modelling of Vortex Induced Vibrations in Submarine Pipelines

F. Van den Abeele, J. Vande Voorde, and P. Goes
ArcelorMittal Research & Development Industry Gent, Zelzate, Belgium

Vortex-induced vibration is a major cause of fatigue failure in submarine oil and gas pipelines and steel catenary risers. Even moderate currents can induce vortex shedding. In this paper, COMSOL Multiphysics is applied to study the flow pattern around submarine pipeline spans, and ... Read More

Uniformity Correction for Fluid Coating Head

W. Vetterling
ZINK Imaging, Bedford, MA, USA

Slot coating is a widely used commercial process for applying one or more thin layers to a substrate such as paper, fabric, film or other material. In many cases, a highly uniform thickness is required, where a coating head that has been corrected for use with a Newtonian fluid may not ... Read More

Simulation of the Dynamic Behavior of a Droplet on a Structured Surface using the Non-conservative Level Set Method

N. Boufercha, J. Sägebarth, and H. Sandmaier
Universität Stuttgart / IFF-MST, Stuttgart, Germany

The ongoing trend towards miniaturization, higher integration as well as cost efficiency will make it necessary to investigate a new assembly method for micro components. In this paper, a novel method of fluidic-based micro assembly is presented. A self-assembly effect which is caused by ... Read More

Full-Wave Simulation of an Optofluidic Transmission-Mode Biosensor

E. P. Furlani[1], N. M. Litchinitse[2], and R. Biswas[2]

[1]The Institute for Lasers, Photonics and Biophotonics, University at Buffalo, Buffalo, New York, USA
[2]Department of Electrical Engineering, The State University of New York at Buffalo,Buffalo, New York, USA

We present a study of an optofluidic biosensor. The sensor operates in a transmission mode wherein detection is based on a shift in the transmission spectrum caused by the contrast in refractive index between the carrier fluid and the target biomaterial. We study the behavior of the ... Read More

Drying of Corn Kernels: From Experimental Images to Multiscale Multiphysics Modeling

P. Takhar[1], and S. Zhang[2]

[1]Texas Tech University, Lubbock, Texas, USA
[2]Visualization Sciences Group Inc., Burlington Massachusetts, USA

This work demonstrated the importance and feasibility of experimental image to simulation workflow. The workflow is successfully applied to a food processing study, where multiphysics and multiscale modeling based on 3D experimental image reconstruction contributes to the preservation of ...

Model of a Filament Assisted CVD Reactor

J. Brcka[1]

[1]TEL US Holdings, Inc., Technology Development Center, Albany, New York, USA

In this presentation we are dealing with the computational fluid model of a Filament Assisted Chemical Vapor Deposition (FACVD) reactor. Proposed strategy in this study involved several steps: (a) development a computational model for FACVD process capable to describe and obtain with ... Read More

Exploratory FEM-Based Multiphysics Oxygen Transport and Cell Viability Models for Isolated Pancreatic Islets

P. Buchwald
Diabetes Research Institute and the Department of Molecular and Cellular Pharmacology, University of Miami, Miller School of Medicine, Miami, FL, USA

Cellular-level oxygen consumption and cell viability models incorporating physiologically realistic assumptions and fully scaled 2D/3D geometries have been implemented in COMSOL Multiphysics for isolated pancreatic islets. Oxygen consumption was assumed to follow Michaelis-Menten–type ... Read More

Effects of Thermal and Electro-Osmotic Flux on Grounding Electrodes

I. Ferreira de Rezende Costa¹, M. C. Barbosa¹, A. De Oliveira Costa Neto²
¹UFRJ, Rio de Janeiro, RJ, Brazil
²UFVJM, Teófilo Otoni, MG, Brazil

Electricity has become the main source of heat, power, and light used in the modern world. Much of the technological advances made over the last few decades are due to electrical energy. One of the essential components of the electrical system is the grounding network. The continuous ... Read More

Mathematical Investigation and CFD Simulation of Monolith Reactors: Catalytic Combustion of Methane

M. Ghadrdan[1], and H. Mehdizadeh[2]
[1]Department of Chemical Engineering, Norwegian University of Science and Technology (NTNU), Trondheim, Norway
[2]Department of Chemical Engineering, Tarbiat Modares University, Tehran, Iran

Interest in the production of hydrogen from hydrocarbons has grown significantly recently. In order to achieve high surface to volume ratio with reasonable pressure drop, monolithic reactors are used. The goal of this work is to develop a two-phase (gas & solid) transient catalytic ... Read More

Reacting Flows in Industrial Duct-burners of a Heat Recovery Steam Generator

G. Petrone[1], G. Cammarata[1], S. Caggia[2], and M. Anastasi[2]
[1]Department of Industrial and Mechanical Engineering, University of Catania, Catania, Italy
[2]Engineering Maintenance - ISAB Energy Services, Priolo Gargallo, Italy

In this study, COMSOL Multiphysics is applied in order to simulate reacting flows for duct burner systems arranged in the post-firing section of a Heat Recovery Steam Generator of a combined cycle power plant. Two- and three-dimensional simulations are carried out in order to ... Read More
