Magneto-hydrodynamic Flow in Electrolyte Solutions

M. Qin[1], and H. Bau[1]
[1]Department of Mechanical Engineering and Applied Mechanics, University of Pennsylvania, Pennsylvania, USA

The paper presents and compares two models for simulating magneto-hydrodynamic flow of RedOx electrolyte in a conduit patterned with circular pillars. The first model solves the coupled Nernst-Planck and Navier-Stokes equations subjected to Butler-Volmer electrode kinetics and provides ... Read More

Coupled Heat, Moisture and CFD Modeling in the Built Environment

K. Kompatscher [1], S. Kochen [1], A. M. W. van Schijndel [1], H. L. Schellen [1]
[1] Department of the Built Environment, Eindhoven University of Technology, Eindhoven, The Netherlands

Museum buildings strive for a stable indoor climate to reduce the risk of cultural object degradation. An incorrect temperature or relative humidity can induce or accelerate deterioration processes such as biological, chemical or mechanical degradation. In order to reduce these risks, ... Read More

An App for Additive Manufacturing Design Assessment

B. Lazaro Toralles [1], S. Afazov [1], A. Yaghi [1], W. A. D. Denmark [1], A.N. Holloway [1],
[1] The Manufacturing Technology Centre Ltd., Coventry, United Kingdom

The Manufacturing Technology Centre (MTC) is home to the UK’s National Centre for Net Shape and Additive Manufacturing, offering integrated solutions to potential end users, supply chain companies or equipment providers using a three phase approach: discovery, demonstration and pilot ... Read More

The Analysis of the Conditions of Flow in the Tundish Performed by a Numerical and Physical Method

T. Merder [1], J. Jowsa [2], A. M. Hutny [2], J. Pieprzyca [1], M. Warzecha [2],
[1] Silesian University of Technology, Katowice, Poland
[2] Czestochowa University of Technology, Czestochowa, Poland

Studies of the liquid metal movement (hydrodynamic) in a real object (tundish) are substantially precluded due to the objective difficulties (high temperature and the size of metallurgical equipment), compared to their execution by the use of physical and numerical modeling. In presented ... Read More

Multiphysics Modeling of Photo-Polymerization in Stereolithography Printing Process and Validation

K. Gao [1], B.L.J. Ingenhut [1], A.P.A. van de Ven [1], F.O. Valega Mackenzie [1], A.T. ten Cate [1],
[1] TNO Materials Solutions, Brightlands Materials Center, The Netherlands

The free-radical photo-polymerization of thermoset polymers is an essential part in additive manufacturing, in particular for the Stereolithography (SLA) printing technique. A better understanding of the photo-polymerization and its relation to the process is required to improve the ... Read More

Model and App of Hydrophobic Meshes Used in Oil Spill Recovery

O. Silva [1], E. Coene [1], J. Molinero [1], B. Shafei [1]
[1] Amphos 21 Consulting S.L., Barcelona, Spain

Hydrophobic meshes are a new, promising technique for the recovery of spilled oil in the ocean. They allow to recover and store oil, while filtering it from the surrounding water. They are clean, efficient and can be used in continuously. These meshes have one drawback, however: if they ... Read More

Design of Dielectrophoretic Cell Traps in Microfluidics Devices Using COMSOL Multiphysics® Software

L. Velmanickam [1], K. Nawarathna [1],
[1] Department of Electrical and Computer Engineering, North Dakota State University, Fargo, ND, USA

The isolation of target cells from biological samples such as serum, urine or blood in high-throughput manner without contamination with other cells is the starting point of developing effective therapy for many diseases. Currently available methods for cell isolation/separation require ... Read More

Analysis of Electromagnetic Behavior of Permanent Magnetized Electrical Machines in Fault Modes

M. U. Hassan [1], R. Nilssen [1], A. Røkke [2],
[1] Department of Electrical Power Engineering, NTNU, Trondheim, Norway
[2] Rolls Royce Marine AS, Trondheim, Norway

The use of Permanent Magnet Synchronous Machines (PMSM) as shaft generators is not new in marine vessels propulsion drive trains. Due to risk of fires in stator windings by internal faults, DNV GL requires the shaft generator to be electrically dead without losing propulsion. This ... Read More

Design of a Self-Recharging Untethered Mobile Inspection Tool inside a Pipeline

W. Chalgham [1], A. C. Seibi [1],
[1] University of Louisiana at Lafayette, Lafayette, LA, USA

Pipeline inspection tools present some limitations related to power supply which require recharging after each operation. Using batteries or tethered tools make the duration to inspect any pipeline very limited and time consuming. This paper aims at designing a spherical self-recharging ... Read More

MHD Electrolyte Flow within an Inter-electrode Gap Driven by a Sinusoidal Electric Field and Constant Magnetic Field

C. Bradley [1], J. Samuel [2],
[1] Benét Laboratories, U.S. Army RDECOM-ARDEC, Watervliet, NY, USA
[2] Department of Mechanical Aerospace and Nuclear Engineering, Rensselaer Polytechnic Institute, Troy, NY, USA

PECM is a necessary extension to traditional ECM for some high-performance materials. Electrolyte flow in the inter-electrode gap (IEG) can be assisted using a magnetic field to allow higher currents, but this creates a magnetohydrodynamic flow. This paper presents a study of flow ... Read More
