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 Simulation of Coupled Fluid-Solid Interaction in Digital Rock Samples

V. Das [1], T. Mukerji [1], G. Mavko [1],
[1] Stanford University, Stanford, CA, USA

Digital rock physics (DRP) is an emerging field where a rock sample is imaged, relevant physical processes are simulated numerically on the digital rock sample, and the numerical solutions are used for understanding and interpreting the rock in different in-situ conditions. The use of ... En savoir plus

Flow Optimization of a MVHR Combined with an Exhaust Air Heat Pump by Means of CFD Simulation

F. Ochs [1], M. Bianchi Janetti [1], M. Romani [2],
[1] University of Innsbruck, Unit Energy Efficient Buildings, Austria
[2] Galletti Group, Italy

In the framework of the Austrian FFG project SaLüΗ!, a compact mechanical ventilation system with integrated micro-heat pump was developed. The aim was a high level of prefabrication and a compact design allowing for installation also in small flats, e.g. into the façade. Due to the ... 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

Thermal and Flow Simulation of a High Temperature Printed Circuit Heat Exchanger

Q. Zhu[1], X. Tan[1], B. Barari[1]
[1]MIT, USA

Printed circuit heat exchanger (PCHE) is a key component in many energy and power systems, such as concentrated solar power plant, nuclear power plant, aircraft, etc. In this paper, the thermal and fluid performance of a lab-scale PCHE is analyzed using COMSOL Multiphysics® simulation ...

Geophysical Fluid Dynamics: Modelling Non-Linearly Viscous Ice-Flow to Obtain Dates of Flow Change

R. Hindmarsh[1]
[1]British Antarctic Survey and Durham University, United Kingdom

Ice flows because at low stresses it deforms viscously; the viscosity depends upon the stress. The lubrication approximation (LA) states shear stress is proportional to the product of the ice depth and surface slope. At ice divides the slope and shear stress are zero meaning the ... 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

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

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
