Application of Solution Mapping to Reduce Computational Time in Actively Cooled Power Electronics

K. Lowe [1,2], and Rao V. Arimilli[2]
[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2]Department of Mechanical, Aerospace, and Biomedical Engineering, University of Tennessee, Knoxville, TN, USA

In some power electronic applications the available coolant temperature is close to maximum and controlling operating temperature becomes more challenging, for which new thermal management schemes must be considered. COMSOL predicts the 3D fluid behavior and 3D temperature distribution ... En savoir plus

Design and Simulation of Indigenous Roll-over Sensor for Four-Wheeler Automobiles

Piyush Raj [1], Adarsh G Datta [1], Vishnu Kumar [1],
[1] Indian Institute of Science, Bangalore, Karnataka, India

In India, more than 150,000 people are killed each year in traffic accidents, according to the Ministry of Road Transport and Highways 2016 report. That’s about 400 fatalities a day, which is far higher than in developed auto markets like the US which, in 2016, logged about 40,000 a ... En savoir plus

Numerical and Experimental Study of Flow, Heat Transfer and Concentration in a Scaled-up Fuel Cell Anode Channel Model

J. C. Torchia-Nüñez[1], and J.G. Cervantes-de-Gortari[1]

[1]Department of Thermal Engineering, National University of Mexico, UNAM, Mexico City, Mexico

Flow, concentration and temperature fields are studied with numerical and experimental methods inside a scaled-up fuel cell anode channel model. The low aspect ratio channel has a porous medium as the inferior wall where a mixing of different pH solutions occurs. Chromatic change of ... En savoir plus

Convective Heat and Moisture Transfer Modelling in Porous Insulation for Large Thermal Storage

Alice Tosatto¹, Michele Bianchi Janetti¹, Fabian Ochs¹
¹Unit of Energy Efficient Building, Universität Innsbruck, Innsbruck, Austria

In view of an energy system based on fluctuating renewable sources, the use of thermal energy storage (TES) systems plays a crucial role. In particular, large-scale underground water-based TES represent a promising solution as demonstrated by a number of cases currently being established ... En savoir plus

Development of a Laser Cladding Process Model

F. Wirth [1], K. Wegener [1],
[1] IWF, ETH Zürich, Switzerland

Additive manufacturing is attracting more and more interest. Laser Cladding is one of these additive manufacturing processes. For this a quasi-stationary physical based 3D process model is presented, which has been developed taking into account heat transfer, melt pool fluid flow ... En savoir plus

Simulation of Magnetically Driven Peristaltic Pumps for Microfluidic Applications

L. Gritter [1], J. Crompton [1], K. Koppenhoefer [1], P. Nath [2]
[1] AltaSim Technologies, Columbus, OH, USA
[2] Applied Modern Physics, Los Alamos National Lab, Los Alamos, NM, USA

Microfluidic technologies can enable laboratory processes to be packaged in miniaturized and automated systems, allowing these processes to be performed with hand-held devices outside a laboratory environment. The practical usefulness of these “lab on a chip” systems has often been ... En savoir plus

Numerical Modelling and Validation of Induction Melting of IN713C for Investment Casting

V U Thomas¹, M A Yar¹, S Mehraban¹, J C T Cullen¹, S G R Brown¹, N P Lavery¹
¹Swansea University, UK

Investment casting is practised in both the automotive and aerospace industries, to produce casted components where a high-quality surface finish is critical. Vacuum induction melting (VIM) and direct pouring into an investment casting shell mould is an advantageous manufacturing ... En savoir plus

In-Situ Detection of Inclusions in Liquid Steel

X. Wang, R. Guthrie, and M. Isac
McGill Metals Processing Centre, Montreal, Canada.

A numerical multiphase flow model is proposed to predict the behavior and motion of entrained inclusions in liquid steel, as they enter the orifice of a LiMCA (Liquid Metal Cleanliness Analyzer) sensor for assuring steel quality. The method of measurement is based on the electric sensing ... En savoir plus

Analysis of Coupled Dynamics of Molten Salt Reactors

V. Di Marcello, A. Cammi, and L. Luzzi
Department of Energy, Nuclear Engineering Division (CeSNEF), Politecnico di Milano, Milano, Italy

This paper presents a preliminary analysis of the coupled thermo-hydrodynamics and neutronics of circulating nuclear fuel systems in a nuclear reactor that adopts a molten salt mixture. This flows up through channels in a graphite moderated core and plays the role of both heat generator ... En savoir plus

Large Scale 3D Flow Distribution Analysis in HTPEM Fuel Cells

C. Siegel[1][2], G. Bandlamudi[1][2], N. van der Schoot[1], and A. Heinzel[1][2]
[1]Zentrum für BrennstoffzellenTechnik GmbH, Duisburg, Germany
[2]Institut für Energie- und Umweltverfahrenstechnik, University of Duisburg-Essen, Duisburg, Germany

Accurate bipolar-plate and flow-field layout is one crucial task for optimizing fuel cells. These cell components perform several functions, including charge transport or gas and water transport throughout the cell just to name a few. Overall, the design depends on the fuel cell ... En savoir plus
