Numerical Study of a DC Electromagnetic Liquid Metal Pump: Limits of the Model

N. Kandev[1]
[1]Institut de recherche d'Hydro-Québec, Shawinigan, QC, Canada

This work presents the results of a 3D numerical magneto-hydrodynamic (MHD) simulation of an electromagnetic DC pump for liquid metal using a rectangular metal flow channel subjected to an externally imposed transversal inhomogeneous magnetic field. In this study. 3D numerical simulation ... Read More

Evaluation of Internal Resistance and Power Loss in Micro Thermoelectric Generators (µTEGs)

S. Seif[1], K. Cadien[1]
[1]Department of Chemical & Materials Engineering, University of Alberta, Edmonton, AB, Canada

One of the major challenges in designing µTEGs is to minimize power loss due to internal resistance (r) of Thermoelectric (TE) materials. To solve this problem we have performed simulation analysis and calculated the internal resistance of eight different TE materials. The internal ... Read More

Effects of Flow and Diffusion on Blood Coagulation in Platelet Poor Plasma: a Two-way Coupling Between Hemodynamics and Biochemistry

D. Magnabosco[1,2], H. van Ooijen[2], B. Bakker[2], R. van den Ham[2]
[1]Politecnico di Milano, Milan, Italy
[2]Philips Research, Eindhoven, The Netherlands

Enzyme reactions, blood flow and diffusion in human vasculature play interacting and fundamental roles in blood coagulation. In this complex mechanism, the balance between blood and clot is a delicate equilibrium, whose tight regulation is vital to avoid pathologies such as bleeding and ... Read More

Flow Analysis and Optimization of a Hierarchical Plate Heat Exchanger for an Adsorption Heat Pump

E. Tempfli[1], F.P. Schmidt[1]
[1]Karlsruhe Institute of Technology (KIT), Fluid Machinery (FSM), Karlsruhe, Germany

The paper investigates the hydrodynamic performance of a hierarchical parallel channel network for the objective of optimal thermal coupling to heat released in the adsorption processes, as in adsorption heat pumps. More specifically, the uniformity of the fluid flow over the network is ... Read More

Design and Simulation of MEMS-based Sensor for Artificial Hand

P. Prema[1], Sakthivishnu.R[1], Sowmya. R[1], Chandra Devi K[1], Meenakshi Sundaram. N[1]
[1]PSG College of Technology, Coimbatore, Tamil Nadu, India

An artificial hand is the one that replaces the hand lost through trauma, disease, or congenital conditions. The proposed design is to simulate a sensor, used in prosthetic hand so as to measure the pressure required to hold the object, using COMSOL Multiphysics®. The physical parameters ... Read More

Numerical Modelling of Solid Oxide Fuel Cells: Role of Various Cell Parameters on Performance

O. Ighodaro[1], K. Scott[1]
[1]Newcastle University, Newcastle upon Tyne, United Kingdom

Solid oxide fuel cells (SOFCs) are expected to play a major role in future energy systems due to their wide range of applications, high energy efficiency, environmental friendliness and good fuel flexibility. While conventional high temperature SOFCs operate at about 1000C, there is ... Read More

Numerical Analysis of Mass Transfer Rate in Droplet Flow at Microscopic Scales new

S. Cito[1], T. Sikanen[1]
[1]Division of Pharmaceutical Chemistry and Technology, Faculty of Pharmacy, University of Helsinki, Helsinki, Finland

Droplet flow at microscopic scale is often used to enhance many pharmaceuticals and industrial processes (i.e. liquid–liquid micro-extraction, nanoparticle synthesis, slow reactions in microfluidic devices, etc.). In all these processes, the mass transfer rate, at the interface between ... Read More

Thermal Field in a NMR Cryostat new

A. D'Orazio[1], C. Agostini[1], S. Fiacco[1]
[1]Dipartimento di Ingegneria Astronautica, Elettrica ed Energetica - Sapienza University of Rome, Rome, Italy

Fundamental component of the NMR tomograph is the magnet. By using the property of superconductivity it is possible to achieve an induction field extremely homogeneous, stable and high. To maintain the material below the superconducting critical temperature (7.2K), the coils are immersed ... Read More
