Fundamental Three Dimensional Modeling and Parameter Estimation of a Diesel Oxidation Catalyst for Heavy Duty Trucks
A. Holmqvist[1] and C.U.I. Odenbrand[1]
[1]Department of Chemical Engineering, Faculty of Engineering, LTH, Lund University, Lund, Sweden
Mathematical optimization can be used as a computational engine to generate the best solution for a given problem in a systematic and efficient way. In the context of monolithic converter systems, the parameter estimation problem (or inverse problem) is solved using Partial Differential Equations (PDE)-based models of the physical system coupled with an optimization algorithm. These problems are ...
Energy Transformation Damping
G.S. Mulder[1]
[1]Leiden, The Netherlands
A model for material damping is presented in terms of internal friction and in terms of a variation of stiffness. In the latter case the idea is that the stiffness increases if elastic energy is stored and decreases if elastic energy is released. In case of a single mass spring system “stiffness” refers to the stiffness of the spring; in case of a continues object &ldquo ...
The Use of COMSOL in Teaching Heat and Moisture Transport Modeling in Building Constructions
A.W.M. van Schijndel[1] and H.L. Schellen[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands
This paper presents the use of the multiphysics package COMSOL for teaching heat and moisture transport modeling in the research area of building physics. It includes a description on how COMSOL works and six exercises with 2D, 3D, steady state and transient models. It is concluded that COMSOL is a very useful tool for this kind of engineering education. Especially, the abstraction level of ...

The development of powerful negative ion sources requires precise and versatile simulation tools to predict the emittance of the extracted ion beams and the heat load on the electrodes. A first tool is a determination of the plasma beam interface which is accomplished by a set of macro based in the COMSOL Multiphysics environment. Notwithstanding the strong nonlinearities involved, a proper ...

In this paper a finite element method(FEM) study of a surface acoustic wave (SAW)device excited by electrostatic coupling method is performed by using COMSOL Multiphysics. We have modeled a Rayleigh wave type SAW device by choosing YZ Lithium niobate as the substrate. The effect of external radio frequency (RF) field to the SAW device is analyzed. The effect of distance between the contactless ...
Thermomagnetic Siphoning on a Bundle of Current-Carrying Wires
J.C. Boulware, and S. Jensen
Space Dynamics Laboratory, North Logan, UT, USA
Using COMSOL Multiphysics, studies were performed showing that thermomagnetic siphoning (TMS) is a sufficient manner of regulating the temperature of a bundle of current-carrying wires wrapped with a magnetorheological fluid (MRF) jacket. Because of Curie’s Law, the cooler MRF on the outside of the jacket is drawn towards the wires due to the induced magnetic field. The process continually ...
Thermal Analysis of Joule Heated Ceramic Melter
P. Goyal, V. Verma, R.K. Singh, and K.K. Vaze
Bhabha Atomic Research Centre, Mumbai, Maharashtra, India
High level radioactive waste (HLW) generated by nuclear fuel cycle is immobilized using glass melters. In Glass melters such as Joule Heated Ceramic Melter (JHCM) electrodes immersed in the glass generates heat by the joule heating due to electric current passing between electrodes through glass. For melter performance it is required to evlaute temperature distribution in the melter. Thermal ...

A Simplified Approach to the Contact in Thermo-mechanical Analysis of Refractory Linings
Y. Kaymak
VDEh Betriebsforschungsinstitut GmbH
Düsseldorf, Germany
The geometrical design and material choice for a refractory lining requires a good understanding of its thermo-mechanical behavior. Design engineers clearly need a tool for fast and efficient computation of thermo-mechanical state of refractory linings under various conditions. However, standard simulation models and their solutions suffer as the linings are composed of many refractory blocks in ...
Optimization of the Lithium Insertion Cell with Silicon Negative Electrode for Automotive Applications

Dearborn, MI
The US Advanced Battery Consortium (USABC) has established goals for long term commercialization of advanced batteries for electric vehicle applications. In this work, a dual lithium-ion insertion cell with silicon as the negative electrode and an intercalation material as the positive electrode is modeled using COMSOL Multiphysics. Both are composite porous electrodes with binder, void ...
