Modeling the Swirling Flow of a Hydrocyclone

B. Chine' [1], F. Concha [2], M. Meneses [3],
[1] Costa Rica Institute of Technology, School of Materials Science and Engineering, Cartago, Costa Rica
[2] Departamento de Ingeniería Metalúrgica, Universidad de Concepción, Concepción, Chile
[3] Costa Rica Institute of Technology, School of Industrial Production Engineering, Cartago, Costa Rica

Hydrocyclones are industrial devices used as processing units in fluid and particle technology. A hydrocyclone is an apparatus consisting of a cylindrical or a cylindrical-conical body with a tangential or involute entrance to admit the fluid inside. There are also two opposite exits, ...

Modeling Polybenzimidazole/Phosphoric Acid Membrane Behaviour in a HTPEM Fuel Cell

C. Siegel[1,2], G. Bandlamudi[1,2], and A. Heinzel[1,2]
[1]Zentrum für BrennstoffzellenTechnik (ZBT) gGmbH, Duisburg, Germany
[2]Institut für Energie- und Umweltverfahrenstechnik, University of Duisburg-Essen, Duisburg, Germany

Phosphoric acid doped polybenzimidazole (PBI) membranes are commonly used in today’s high-temperature polymer-electrolyte-membrane (HTPEM) fuel cell technology. COMSOL Multiphysics is used to model and simulate the three-dimensional, single-phase, non-isothermal overall cell behaviour ... En savoir plus

Optimal Design for the Grating Coupler of Surface Plasmons

Y. Huang

Mathematics Department, University of California, Los Angeles, CA, USA

We present an optimization procedure to optimize the maximum coupling of free space optical wave to surface plasmon. Shape derivative from shape sensitivity analysis is calculated, and the corresponding partial derivatives of the objective functional with respect to finite number of ... En savoir plus

Modeling the Effect of a Crack on the Flow-Induced Vibration of Supported Pipes

J. H. Lee [1], S. M. Al-Said [2],
[1] American University of Sharjah, Sharjah, United Arab Emirates
[2] Jordan University of Science and Technology, Irbid, Jordan

In this paper, the effect of a crack to the flow-induced vibration characteristics of supported pipes is investigated based on vibration method. In order to estimate the crack location and depth in the pipe, we need to utilize the variation of the difference between the natural ... En savoir plus

Thermo-Mechanical Modeling of Laser Beam Welding of Molybdenum

K.-H. Leitz [1],
[1] Plansee SE, Reutte, Austria

Laser beam welding is a key technology in industrial manufacturing as it combines high flexibility and the potential for automation with excellent joint quality and minimal thermal influence of the workpiece. Whereas for materials like steel and aluminium laser beam welding is already ... En savoir plus

Design of Arrayed Micro-Structures to get Super-Hydrophobic Surface for Single Droplet and Bulk Flow Conditions

A. Mall[1], P. R. Jelia[1], A. Agrawal[1], R. K. Singh[1], and S. S. Joshi[1]

[1] Department of Mechanical Engineering, Indian Institute of Technology Bombay, Maharashtra, India

Surfaces with water contact angle greater than 150º are super-hydrophobic in nature and possess extraordinary water repelling properties. Various researches on wettability of textured surfaces in recent years have shown that texturing surfaces with micron-sized and nanosized patterns ... En savoir plus

Anisotropic Damping in MEMS Oscillator

S. Silvestrini [1],
[1] Delft University of Technology, Delft, Netherlands

The analyzed MEMS oscillator is composed by a spring (beam) supported mass that needs to vibrate with a high Q-factor in the horizontal plane. Nevertheless, the transverse motion needs to be highly damped (low Q-factor). The purpose of the work was to explore different system ... En savoir plus

The Role of COMSOL Toward a Low-Enriched Uranium Fuel Design for the High Flux Isotope Reactor

J.D. Freels[1]
[1]Oak Ridge National Laboratory, Oak Ridge, Tennessee, USA

Design and safety analyses are underway to convert the High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) from a high-enriched uranium (HEU) fuel to a low-enriched uranium (LEU) fuel. The primary constraint for the project is that the overall fuel plate ... En savoir plus

Enhanced Fin Tube Heat Exchanger Design Through Topology Optimization

Shi Zeng [1],
[1] National University of Singapore, Singapore

Fin tube heat exchangers are widely used in air conditioning systems. Various fin structures have been proposed and studied in literature to enhance their heat transfer performance. However, enhancement in heat transfer is often accompanied by pressure drop penalty. This study utilized a ... En savoir plus
