Heat Transfer and Phase Change

Implementation of an Active Fluid Cooling Design in a 48 V High-Power Battery Module

Z. Wu [1], A. Stawarski [2], H. Kemper [2],
[1] Energy Storage Systems, FH Aachen - University of Applied Sciences, Aachen, Germany; RWTH Aachen University, Aachen, Germany
[2] Energy Storage Systems, FH Aachen - University of Applied Sciences, Aachen, Germany

Individual batteries have their own operational temperature ranges, which shall be respected to avoid both damaging of the cells and shortening of the cycle life. In terms of the Li-Ion cells, many of them do not function well at higher temperatures. Therefore, a better understanding of ... Read More

Simulation of Dynamic Thermal Fields Assisting DMLS Additive Manufacturing of Biocompatible Ti-Alloy

E. Lacatus [1], G. C. Alecu [2], M. Sopronyi [3],
[1] Polytechnic University of Bucharest, Bucharest, Romania
[2] Groupe Renault, Bucharest, Romania
[3] National Institute for Laser, Plasma and Radiation Physics (INFLPR), Magurele, Romania

For the complex 3D biocompatible metallic parts, with high level of customization, used in medical prosthesis and implants Direct Metal Laser Sintering (DMLS) and Selective Laser Melting (SLM) are the most common Additive Manufacturing technologies used nowadays. However, both ... Read More

Phase Transformation and Deformation Model for Quenching Simulations

Y. Kaymak [1],
[1] VDEh Betriebsforschungsinstitute GmbH, Düsseldorf, Germany

Heat treatment of the advanced steel grades (like micro-alloyed steels or AHSS steel grades) is a challenging process as the residual stress/deformation are very pronounced and the customer quality requirements are getting stricter. Instead of a trial and error based process control, a ... Read More

Iron Ore Sintering Process Model to Study Local Permeability Control

Y. Kaymak [1], T. Hauck [1], M. Hillers [2],
[1] VDEh Betriebsforschungsinstitute GmbH, Düsseldorf, Germany
[2] Shuangliang Clyde Bergemann GmbH, Ratingen, Germany

The iron ore sintering process prepares fine iron ore for the blast furnace process. A mixture consisting of iron ore, coke (fuel) and additives is ignited at the top and air is sucked from below to move a combustion front down through the bed. Most of the sintering plants use ... Read More

Validation of COMSOL Multiphysics® for Magnetohydrodynamics (MHD) Flows in Fusion Applications

Y. Yan [1], S. Smolentsev [1], M. Abdou [1]
[1] Fusion Science and Technology Center, University of California, Los Angeles, CA, USA

Several commercial CFD companies have recently extended their codes to magnetohydrodynamic (MHD) flows. However, there are many computational challenges associated with MHD flows under the harsh fusion environmental conditions that require such codes to be carefully examined in a special ... Read More

The APP as a Tool, A First Principles Approach

R. W. Pryor[1],
[1] Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

The app discussed in this paper is based on a COMSOL Multiphysics® 1D heat transfer model that analyses the heat flow through a double pane window, with a gas chamber between the two panes, as would normally be mounted in the wall of a building, a container or a refrigerated chamber. The ... Read More

Numerical Model Simulation of Impedance Based Control for RF Ablation Using Isolator Synergy Clamp

M. Etheridge [1], R. Lopusnik [1], A. Cates [1],
[1] AtriCure, Inc., Minnetonka, MN, USA

Thermal ablation is rapidly becoming a standard of care for the treatment of atrial fibrillation (AF), a cardiac disorder characterized by irregular heart rhythm and estimated to impact more than 33 million people worldwide (Chugh et al. Circulation (2013)). AtriCure is a company that ... Read More

Numerical Simulation of Pool Film Boiling Heat Transfer during Quenching of Heated Cylindrical Rods

S. Ebrahim [1], F. B. Cheung [1], A. Alshayji [2],
[1] Department of Mechanical and Nuclear Engineering, Pennsylvania State University, University Park, PA, USA
[2] Department of Mechanical Engineering, College of Engineering and Petroleum, Kuwait University, Kuwait

This research studies possible ways to mitigate failure of a nuclear reactor, in which the coolant supply to the nuclear core has been compromised, known as Loss of Coolant Accident (LOCA). One possible way to decrease the severity of the incident is to quickly quench the fuel rods in ... Read More

Thermal Model and Control of Metal-Organic Chemical Vapor Deposition Process

J. L. Ebert [1], S. Ghosal [1], N. Acharya [1]
[1] SC Solutions, Inc., Sunnyvale, CA, USA

Metal-Organic Chemical Vapor Deposition (MOCVD) is used for the manufacture of Multi-Quantum Well Light Emitting Diodes (MQW LEDs). The process uses a carrier gas flow containing a dilute mixture of metal organic precursors, Tri-Methyl Gallium (TMG) and Tri-Methyl Indium (TMI), to ... Read More

3D Unsteady CFD with Heat and Mass Transfer Simulations of Solar Adsorption Cooling System for Buildings

W. Yaici [1], E. Entchev [1], J. Ranisau [1],
[1] CanmetENERGY Research Centre, Natural Resources Canada, Ottawa, ON, Canada

In recent years, extensive attention has been paid on the application of solar cooling for buildings. Amongst cooling technologies, low-temperature solar-driven adsorption cooling systems are emerging viable alternatives to electricity-driven vapour compression systems. They seem to have ...
