Numerical Model For Rocking Of Mono-Pile In A Porous Seabed

D-S. Jeng, X. Luo, and J. Zhang
Division of Civil Engineering, University of Dundee, Dundee, Scotland, UK

Offshore wind and wave energy industries have developed considerably in the last two decades. Most offshore energy structures used in the existing projects are mono-piles in shallow water due to simplicity of installations, design and control. Numerous research for the design and ...

Modeling Self-Potential Effects during Reservoir Stimulation in Enhanced Geothermal System

G. Perillo[1], A. Monetti[2], A. Troiano[2], M. G. Di Giuseppe[2], C. Troise[2], G. De Natale[2]
[1]University of Naples Parthenope, Naples, Italy
[2]INGV-Osservatorio Vesuviano, Naples, Italy

Geothermal systems represent a large resource that can provide, with a reasonable investment, a very high and cost-effective power generating capacity. Despite its unquestionable potential, geothermal exploitation has long been perceived as limited, mainly because of the dependence from ... En savoir plus

Increasing Heat Transfer in Microchannels with Surface Acoustic Waves

S. Berry[1]
[1]Massachusetts Institute of Technology: Lincoln Laboratory, Lexington, MA, USA

In this numerical study, surface acoustic waves (SAWs) are evaluated as a potential disruptive flow technology for enhancing heat transfer in microchannels. Using COMSOL Multiphysics® software, the physics governing acoustics, single-phase-fluid flow and heat transfer are coupled. The ... En savoir plus

Integration of the DeProF Model for Two-Phase Flow in P.M. into the Subsurface Flow Module

[1] TEI Athens, Athens, Greece
[2] FORTH/ICE-HT, Patras, Greece
[3] TEI of Western Greece, Patras, Greece

Relative permeability maps for steady-state two-phase flow in porous media, delivered by implementing the DeProF model [1] algorithm, were integrated within COMSOL Multiphysics® software [2] to resolve field-scale flows in porous media. The mechanistic model DeProF [1], predicts the ... En savoir plus

Analysis of Fluid Pumping with a Throttle Type Piezoelectric Micro Pump

B. Pe?ar[1], D. Križaj[1], D. Vrta?nik[1], D. Resnik[1], U. Aljan?i?[1], M. Možek[1], T. Dolžan[1], A. Slavko[1]
[1]Faculty of Electrical Engineering, UNI of Ljubljana, Ljubljana, Slovenia

Operation of a modified type microthrottle (MT) pump is analyzed by numerical simulation. Conventional MT pumps have disk type piezoelectric membranes while the analyzed type has a membrane of a rectangular shape. This could be advantageous in case the pump is stacked into an array for ... En savoir plus
