Mixing Layer Analysis in Variable Density Turbulent Flow

A.E. Alshayji[1]
[1]Department of Mechanical Engineering, College of Engineering and Petroleum, Kuwait University, Safat, Kuwait

In this study, numerical simulations of mixing in turbulent flow, subject to a change in density, are performed. Attention is focused on the binary mixing between two streams of fluid in which a variable density step are formed due to a difference in the temperature. This binary mixing ... Read More

Numerical Modeling of 3D Electrowetting Droplet Actuation and Cooling of a Hotspot

M. M. Nahar [1], H. Moon [1], G. S. Bindiganavane [1], J. Nikapitiya [1]
[1] Department of Mechanical and Aerospace Engineering, University of Texas - Arlington, Arlington, TX, USA

Electrowetting on Dielectric (EWOD) is a versatile tool for performing basic operations in Digital Microfluidic Systems. In EWOD, surface tension between a liquid droplet and solid substrate is modulated by applying voltage to an electrode and a hydrophobic surface is transformed into a ... Read More

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

Energy Harvesting in a Fluid Flow Using Piezoelectric Materials

M. Curatolo [1], M. La Rosa [1], P. Prestininzi [1],
[1] Roma Tre University, Rome, Italy

Energy harvesting from a fluid flow using piezoelectric materials is a relatively recent topic that has been investigated experimentally and numerically [1, 2]. Its possible application in natural water currents represents an interesting strategy to easily harvest renewable energy from ... Read More

Highly Concentrated Solar Radiation Measurement by Means of an Inverse Method

[1]ENEA - Italian National Agency for New Technologies, Energy and Sustainable Economic Development, Portici, Italy
[2]DETEC - Università degli Studi di Napoli Federico II, Napoli, Italy

This work focuses on the numerical analysis conducted on the prototype sensor for the measurement of highly concentrated radiative heat fluxes, based on an inverse heat transfer method, realized at the ENEA Portici Research Center in collaboration with the DETEC department of the ... Read More

Full Coupling of Flow, Thermal and Mechanical Effects in COMSOL Multiphysics® for Simulation of Enhanced Geothermal Reservoirs

D. Sijacic[1], P. Fokker[1]
[1]TNO, Utrecht, The Netherlands

The effective modeling of enhanced geothermal systems (EGS) requires the coupling of geomechanics, fluid flow and thermal processes. An understanding of the complete system with these coupled processes is vital, not just for reservoir stimulation targeted at enhancing reservoir ... 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
