Surface Acoustic Wave Properties (SAW) and Acoustic Streaming Characterization for Annular and Curved Electrodes on 128˚ Y-Cut, X-Propagating LiNbO3

G. Potter[1], N. Tokranova[1], S. Gattu[1], J. Castracane[1]
[1]SUNY College of Nanoscale Science and Engineering, Albany, NY, USA

Microfluidic devices and lab-on-a-chip (LOC) require the ability to transport or pump reagents or reaction products, the ability to effectively mix small volumes of fluid, and provide direct data display. Surface acoustic wave (SAW) driven acoustic streaming generated by a piezoelectric ... En savoir plus

Design and Simulation of Sensors to Detect Methanol

C. K. Subramaniam[1], Muthuraja[1]
[1]School of Electronics Engineering, VIT University, Vellore, Tamil Nadu, India

The Direct Methanol Fuel Cell (DMFC) working is dependent on the concentration of methanol in water before it is introduced in the anode. DMFC has a high energy density when generating electrical power from fuel, and is an attractive power source for portable devices. A fundamental ... En savoir plus

Fluid Motion Between Rotating Concentric Cylinders Using COMSOL Multiphysics® Software

P. L. Mills [1], K. Barman [1], S. Mothupally [1], A. Sonejee [1],
[1] Texas A&M University - Kingsville, Kingsville, TX, USA

Introduction Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, ... En savoir plus

Simulation of the Cooling and Phase Change of a Melt-Cast Explosive

W. Sanhye [1], C. Dubois [1], P. Pelletier [2], I. Laroche [2],
[1] Department of Chemical Engineering, École Polytechnique de Montréal, Montréal, QC, Canada
[2] General Dynamics Ordnance and Tactical Systems-Canada Inc., Repentigny, QC, Canada

Introduction Numerical modeling of melt-casting is becoming a popular tool for the energetic materials and explosives industry. Compared to traditional metal casting, the cooling cycle for explosive melts is significantly longer because of their high Prandtl numbers [1]. Improving the ... En savoir plus

Simulation of Deep Geothermal Heat Production

E. Holzbecher, P. Oberdorfer, F. Maier, and Y. Jin
Georg-August Universität Göttingen
Göttingen, Germany

Geothermal heat production from deep reservoirs (5000-7000 m) is currently examined, not only in Germany. Our reference set-up consists of two pipes within a single borehole: one for pumping. We examine a design, where a single borehole splits into two legs at a certain depth. The two ... En savoir plus

Simulation of a Plastic Bottles Solar Collector

V. Bonetti[1]
[1]Ingegneria Senza Frontiere, DESE, Università di Pisa, Pisa, Italy

In the Andean region of Southern Peru, poverty and climate are extreme: at 4000mt asl, insolation is among the highest in the world but the temperature varies more than 30 degrees between day and night. At the community of Livitaca (Cuzco), the association “Ingegneria Senza Frontiere” is ... En savoir plus

Effect of Magnetic Field on MR-Fluid in Ball End Magnetorheological Finishing

H. Garg[1], V. S. Negi[1], A. S. Kharola[1], R. Sharma[1]
[1]CSIR - Central Scientific Instruments Organization, Chandigarh, India

Magnetorheological Finishing (MRF) is one of the precision finishing processes in which magnetic field is used to drive abrading forces for Finishing 2D and complex 3D surfaces. In this paper, Ball End Magnetorheological Finishing (BEMRF) has been analyzed for fluid behaviors under the ... En savoir plus

Simulation and Optimization of the Speed Flow in COMSOL Multiphysics® during the Suction of the Dust Pump for Granite Polishing Operation
