Performance Prediction of Eddy Current Flowmeter for Sodium

P. Sharma[1], S. K. Dash[1], B. K. Nashine[1], S. S. Kumar[1], R. Veerasamy[1], B. Krishnakumar[1], P. Kalyanasundaram[1], and G. Vaidyanathan[1]
[1] Fast Reactor Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu

Sodium is used as a coolant in Fast Breeder Reactors. Eddy Current Flowmeter (ECFM) is used for measurement of sodium flow in the primary pump and at the outlet of the subassemblies. Eddy Current Flowmeter (ECFM) works on the principle of change in the magnetic field profile due to ... Read More

A Heat Transfer Simulation for Heat Management in the Design of a New ReactorSTM

Elahe Motaee¹, Dr. Irene M.N. Groot¹
¹Leiden University

With the ReactorSTM the relationship between surface structure and catalyst activity under industrially relevant conditions can be investigated. It enables atomic-scale observations of model catalysts under conditions approaching those used by the chemical industry. It consists of a ... Read More

Damping in Dense Gas Acoustic Structure Interaction

J. P. M. Smeulers [1], H. P. Pereboom [1], N. González Díez [1],
[1] TNO, Delft, The Netherlands

Large centrifugal compressors, which are commonly applied in the oil and gas and in the process industry, may fail due to vibrations of the impeller. These vibrations are induced by pressure pulsations in a compressor stage. These vibrations can be especially strong in so-called dense ... Read More

To a Fluidic Diode for Biomedical Application

[3] Biomedical Engineering laboratory, University of Tlemcen, Algeria

This work is focused on Micropump optimization for drug delivery application. Diabetes is one of the widely pervaded diseases. Among the side effects of hyperglycemia is the weakness of the whole body, so the patient will be unable to inject manually the drug. Therefore, Micropumps are ... Read More

Chaining Dynamics of a Pair of Ellipsoidal Micro-Particles Under a Uniform Magnetic Field

J. Zhang[1], C. Wang[1]
[1]Missouri Univ of Sci and Tech, USA

Due to particle interactions, magnetic particles suspended in non-magnetic fields tend to form chains, clusters or columns under magnetic fields. The non-spherical magnetic particles in the suspension show different rheological properties compared to spherical particles. In this paper, ... Read More

3D Acoustic-Structure Interaction of Ultrasound in Fluids for the Manufacture of Graded Materials

J. Holt [1], C. Torres-Sanchez [1], P. Conway [1], M. G. Garcia-Romero [1],
[1] The Wolfson School of Mechanical, Electrical and Manufacturing Engineering, Loughborough University, Leicestershire, UK

Functionally graded materials (FGM) are those that contain chemical, phase or structural gradients. Whilst the design of functionally graded structures is well researched in areas such as shape optimisation and topology optimization, their manufacture is still in development. One ... Read More

Simulation of a Novel Induced-Charge Electrokinetic Actuation Mechanism for a Diaphragm Micropump

A. Eden[1], F. Lorestani[1], S. Mackenzie[1], S. Minne[1], D. Huber[1], C. Meinhart[1], S. Pennathur[1]
[1]University of California, Santa Barbara, USA

From microelectronics cooling to biological analysis and wearable therapeutic infusion systems, micropumps are steadily becoming a valuable and ubiquitous tool for fluid transport and thermal management. Hence, the development of novel actuation mechanisms that allow for precise ... 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

Simulation of CMOS Compatible Sensor Structures for Dielectrophoretic Biomolecule Immobilization

H. Matbaechi Ettehad [1], S. Guha [1], C. Wenger [1],
[1] IHP, Frankfurt (Oder), Brandenburg, Germany

The aim of this paper is to optimize with COMSOL Multiphysics® simulation, the design geometry of a near field biosensor which could be used for dielectrophoretic (DEP) immobilization and simultaneous sensing of biomolecules of the order of nanometers to micrometers. COMSOL Multiphysics® ... Read More

Development of a Numerical Model for Large-Scale Seasonal Thermal Energy Storage for District Heating Systems

A. Tosatto[1], A. Dahash[1], F. Ochs[1], M. Bianchi Janetti[1]
[1]University of Innsbruck - Unit of Energy Efficient Buildings, Austria

The integration of a Thermal Energy Storage (TES) system in District Heating (DH) networks allows increasing the share of renewables in the energy scheme, but it requires a proper pre-design phase in which the modelling of the TES system is adequately driven. The main purpose of this ... Read More
