[1]DICAM, Università di Bologna, Italy
[2]Civil Engineer, Italy
[3]IMAGE, Università di Padova, Italy

This paper will present a numerical model based on COMSOL Multiphysics suited to simulate the dynamic response of a catenary mooring (or a submarine cable). In general, mooring lines are subject to a direct wave load (e.g. drag, inertia) in addition to the movement of the vessel to which they are linked. Tests were carried out at the wave flume of the Maritime Laboratory of IMAGE Department, ...

Modeling CO2 storage Using Coupled Reservoir-Geomechanical Analysis

T.I. Bjørnarå, F. Cuisiat, E. Aker, and E. Skurtveit
Norwegian Geotechnical Institute(NGI), Oslo, Norway

The geomechanical effects related to CO2 injection into the Krechba formation at In Salah, Algeria, are considered through a coupled modeling approach to simulate simultaneously CO2 migration in the aquifer and the surrounding formations, as well as the poro-elastic stress changes occurring during injection. The model is based on the simultaneous resolution of the governing equations for two ...

Thermal Properties of Copper Tungsten with Copper Via Composite

J. Ma[1], A. Parker[1], and K. Kuan[2]
[1]Southeastern Louisiana University, Hammond, LA, USA
[2]Torrey Hill Technology LLC, SanDiego, CA, USA

This study focuses on a low-cost composite material based on CuW with Cu via, which functions as a more efficient thermal path for heat conduction. A 50mm X 50mm X 1mm CuW(15/85) speciman consists an array of 30X30 uniformly distributed cylindrical Cu via attaching to a microprocessor generating 100 watts power was studied. By calculating the heat flux coming out of the top and the ...

Investigations on Hydrodynamic in Stirred Vessels for Educational Purposes

A. Egedy, T. Varga, and T. Chován
University of Pannonia
Department of Process Engineering
Veszprém, Hungary

With detailed hydrodynamic modelling of a system the critical parameters and operation limits can be determined. In the field of fluid dynamic and reactor engineering one of the most important aspects is the practical knowledge of future engineers and technicians. In our research several different reactor constructions and impeller configurations were modelled to achieve a better ...

Matching 4D Porous Media Fluid Flow GeoPET Data With COMSOL Multiphysics Simulation Results

J. Lippmann-Pipke, J. Kulenkampff, G. Marion, and M. Richter
Helmholtz-Zentrum Dresden
Rossendorf, Institut of Radiochemistry
Research Site Leipzig
Reactive Transport Division
Leipzig, Germany

We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import “realistic structures” from geologic samples scanned by means of computer tomography (CT) as stl-files into COMSOL ...

Super-resolution Properties of the Maxwell Fish-Eye

D. Grabovickic, J. C. Gonzalez, J. C. Miñano, and P. Benitez
Universidad Politecnica de Madrid
Madrid, Spain

In this paper we present an analysis that shows the Maxwell Fish Eye (MFE) only has super-resolution property for some particular frequencies (for other frequencies, the MFE behaves as conventional imaging lens). These frequencies are directly connected with the Schumann resonance frequencies of spherical symmetric systems. The analysis have been done using a thin spherical waveguide (two ...

3-Dimensional Blood Cooling Model inside a Carotid Bifurcation

R. Sikorski[1], T. Merrill[1]
[1]Rowan University, Glassboro, NJ, USA

Stroke is caused by an interruption of brain blood supply and is one of the leading causes of death and disability. A mild reduction of 2-5°C in tissue temperature through hypothermia has shown reduced tissue infarct size, increased tissue recovery, and positive neurological effects. This paper seeks to predict the outlet blood temperature in the common carotid bifurcation branches. In our ...

Numerical Simulation of Flow Electrolysers: Effect of Various Geometric Parameters

Micro Mirror is a versatile device which has been gaining popularity and also the importance of MEMS techniques to develop such devices. These mirrors find applications in fields such as optical switching, display and in medical fields for non-invasive imaging. A thermally actuated mirror moves in either vertical or horizontal directions for the given orientation. The ends of thermal actuators ...
