Pyrochemical process based on molten salt electrorefining is ideally suited for reprocessing spent metallic fuels from Fast Breeder Reactors. In this work, a heat transfer analysis of the Electrorefiner cell was conducted to develop a basic tool for designing of the engineering–scale Electrorefiner. The focus of this work is to find out steady state temperature profiles of cover gas and molten ...

In this work the issue of saturation phase erosion caused by groundwater leakages was approached both experimentally and computationally by employing COMSOL\'s Earth Science Module. We evaluated the total mass of eroded bentonite out of a cylindrical erosion channel both numerically and experimentally, and studied its dependence on time. It was observed that logarithmic eroded mass loss as a ...

Investigation Of Bone Marrow Stem Cells In The Bone Marrow Niche In An In Vitro System

P. Lezuo, M. Stoddart, and M. Alini
AO Research Institute, Davos, Grison, Switzerland

We aim to develop an in vitro culture system to mimic the human bone marrow stem cell niche in an artificial perfusion bioreactor environment to culture human adult stem cells. State of the art human bone marrow stem cell research shows that even smallest changes in the physical, thermo dynamical or biochemical environment induce a differentiation of human bone marrow stem cells into other cell ...

Numerical Modelling of Compact High Temperature Heat Exchanger

O. Smirnova, T. Fend, and D. Schöllgen
Institut of Solar Research in German Aerospace Agency
Cologne, Germany

For the numeric investigations of the high temperature compact heat exchanger two numeric models with and without the regards of the velocity field development were used. The results of the comparison of the numeric and experimental data confirm the necessity of regarding the velocity field development for the compact heat exchangers. The two-dimensional simulation task with the regard of ...

Development of Mathematical Model for Determining Sound Reduction Index of Building Elements

J. Ratnieks, A. Jakovics, and J. Klavins
University of Latvia
Riga, Latvia

Although we know the physics inside a media where the sound waves propagate, determination of material\'s or structure\'s sound reduction index is not an easy task. The lack of good engineering solutions proves the point. The only reliable way to calculate the sound reduction index is to carry out an experiment.Therefore, the aim of this study is to develop a mathematical model that can ...

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 ...

Numerical Experiments for Thermally-induced Bending of Nematic Elastomers with Hybrid Alignment

L. Teresi[1], and A. DeSimone[2]
[1]LaMS - Modeling & Simulation Lab, University Roma Tre, Roma, Italy
[2]SISSA - International School for Advanced Studies, Trieste, Italy

We deal with Liquid Crystal Elastomers (LCEs) having hybrid alignment (HNEs), that is, fabricated with a given non-homogeneous nematic orientation. For such a materials, permanent distortions induced by deswelling can be compensated by those resulting from cooling below the transition temperature, thus yielding the possibility of producing temperature-driven actuators. Here, we simulate the ...

A High-Efficiency Micro-Channel Regenerative Heat Exchanger for Fluid Processing

O. Yildirim, and Z. Guo
Intellectual Ventures Laboratories
Bellevue, WA

Regenerative heat exchangers (RHX) find widespread applications in liquid food or pharmaceutical processing as well as in reaction engineering. Whereas \"large\" RHX systems have been in use for a long time, their smaller micro-channel counterparts are a more recent area of interest. Here, we describe the design and development of a novel micro-channel counter-current regenerative heat ...

Dynamic Simulation of Bone Morphogenetic Protein Patterning in a 3D Finite-Element Model of the Danio Rerio Embryo

D. Umulis, and S. Lee
Purdue University
West Lafayette, IN

Zebrafish development of the dorsoventral axis relies on the spatiotemporal distribution of Bone Morphogenetic Protein (BMP) signaling, which is regulated by numerous secreted molecules such as Tolloid, Sizzled, and Chordin. The rich dorsal/ventral patterning network must achieve both spatial precision in the patterning of downstream targets and confernspatial precision at distinct time points in ...
