Simulating the Effect of Groundwater Flow and Heterogeneity on Borehole Thermal Energy Storage

M. Possemiers [1], L. De Henau [1], J. Van Steenwinkel [1],
[1] AGT - Advanced Groundwater Techniques, Aartselaar, Belgium

In Borehole Thermal Energy Storage (BTES), also called closed loop ground source heat pumps (GSHP) or closed systems, the thermal energy is stored and recovered with a closed hydraulic circuit consisting of one or more boreholes with vertical heat exchangers. The heat exchangers consist ... Read More

Heat and Moisture in Wooden Bearings of Monuments

H. L. Schellen [1], M. Spierenburg [2], A. W. M. van Schijndel [1],
[1] Eindhoven University of Technology, Eindhoven, The Netherlands
[2] 2DPA Cauberg-Huygen, Amsterdam, The Netherlands

Nowadays, thermal insulation is applied to most buildings. However, this proves to be a challenge for most monumental buildings. When insulation needs to be applied at the interior side of a building, thermal bridges are inevitable. Wooden beam ends beared in an external wall are an ... Read More

Model Based Stimulus Experiments to Improve Biological Wastewater Treatment Performance

N. Do [1], M. Stich [1],
[1] Non-linearity and Complexity Research Group, System Analytics Research Institute, School of Engineering and Applied Science, Aston University, Birmingham, United Kingdom

The municipal wastewater treatment in a sustainable context requires a smart technology in which an optimal combination of the ecological status and energy demand can be achieved. The integration of electron conductive materials into a traditionally constructed wetland (CW) has been ... Read More

Exergy Analysis of Polymer Flooding in Clastic Reservoirs

[1] Delft University of Technology, Delft, The Netherlands, and Sudan University of Science and Technology, Khartoum, Sudan
[2] Delft University of Technology, Delft, The Netherlands
[3] Sudan University of Science and Technology, Khartoum, Sudan

Using a 1-D model of polymer displacement, we analyze the exergy (maximum attainable work) balance of viscosifi ed water, e.g. with Arabic gum. The 1-D model shows the principle how such an analysis can be done. A comparison as to the displacement efficiency is made between three ... Read More

A Multiphysics Model of O2 Transport and Recirculation During Venovenous Extracorporeal Life Support

S. Conrad [1],
[1] Louisiana State University Health Sciences Center, Shreveport, LA, USA

Venovenous extracorporeal life support (VV-ECLS) provides gas exchange support for severe lung failure by using an extracorporeal circuit consisting of a blood pump and an artificial membrane lung. Blood is withdrawn from a cannula placed into the inferior vena cava, and returned from ... Read More

Study of Rotation of Ellipsoidal Particles in Combined Simple Shear Flow and Magnetic Fields

C. Wang [1], J. Zhang [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study creates a 2D fluid-structure interaction (FSI) model to study the effect of magnetic field and particle aspect ratio on the period of rotation and symmetry of ellipsoidal paramagnetic particles. The results show that the magnetic field strength has a significant effect on the ... Read More

Numerical Modeling of Nanopipettes for Electrophysiology and Imaging

J. Rabinowitz [1],
[1] Columbia University, New York, NY, USA

Nanoscale pipettes allow for exciting extensions of traditional current- and voltage-clamping electrophysiology experiments. However, bulk electrodynamic properties begin to break down at nanoscale openings, introducing unusual effects that must be understood in order to properly ... Read More

Modeling Internal Erosion Processes in Soil Pipes

J. L. Nieber [1], G. V. Wilson [2], G. A. Fox [3],
[1] University of Minnesota, St. Paul, MN, USA
[2] United States Department of Agriculture - Agricultural Research Service National Sedimentation Laboratory, Oxford, MS, USA
[3] North Carolina State University, Raleigh, NC, USA

The erosion of the interior of soil pipes is an important process in the fields of geomechanics and geomorphology. Soil pipes can form in water holding structures like dams and levees, and water flow through these structures becomes concentrated into the soil pipes as they evolve by the ... Read More

Electrochemical Machining with Nonsymmetric Suction of Electrolyte Flow

M. Hashiguchi [1], D. Mi [1],
[1] Keisoku Engineering System Co. Ltd., Tokyo, Japan

In electrochemical machining process, it is very important to control electrolyte flow field to remove contamination such as slug, or gas to be generated by the machining process as well as heat control for electrolyte, machining tool and work piece. To reduce the overcut of workpiece, ... Read More
