[1]ABB Corporate Research, Västerås, Sweden
[2]COMSOL AB, Stockholm, Sweden

For certain classes of scientific and technical computations the cloud may offer easily accessible, scalable, and affordable gigantic computing power. A power that for these classes may lead to a step change in model and analysis complexity compared to what is feasible with dedicated clusters and similar networked solutions. Acoustics with or without interaction with coupled physics fields ...

Blood Flow Patterns in a Patient Specific Right Coronary Artery with Multiple Stenoses - new

B. Liu[1]
[1]Department of Mathematics, Monmouth University, West Long Branch, NJ, USA

Atherosclerotic lesions preferentially develop in certain regions like bifurcations, branches, and bends [1, 2]. A possible explanation for such a preferential localization of atherosclerosis is that the geometry of the vessel influences the blood flow pattern. It suggests that the arterial geometry plays an important role in determining the localized blood flow information. Thus hemodynamic ...

A Simulation App for Determining How Best to Cool a Beer Bottle

J. Richter[1], T. Hilbig[1], C. Schröder[1]
[1]University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany

The scope of this project was the creation of a short and comprehensive tutorial for the use of COMSOL® Application Builder for students at the University of Applied Sciences Bielefeld. The tutorial is based on the everyday life “problem” how to cool a beer bottle most efficiently. It shows how to use the most important features and tools (e.g. creating buttons, input fields, methods, generating ...

Computation of Three-Dimensional Electromagnetic Fields for an Augmented Reality Environment

A. Buchau, and W. Rucker
Institut für Theorie der Elektrotechnik, Universität Stuttgart, Germany

Augmented reality is predestined for visualization of electromagnetic fields in air or inside transparent matter. Real existing objects are studied and invisible electromagnetic fields are added as virtual objects. Hence, experts as well as students are able to connect electromagnetic fields easily with studied objects. They can concentrate on physical effects instead on reading figures. Here, ...

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 ...

Simulation of Beverage Refrigeration with Dependence on Container Shape, Material and Orientation

[1]University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany

Adequate cooling of beverages is a major issue in planning of several types of events, e.g. poster sessions at conferences. One crucial factor is the time needed to cool beverages from its initial temperature to the desired drinking temperature. We present a way to determine a close approximation for the cooling behavior of three types of commonly used beverage containers using COMSOL ...

Electromagnet Shape Optimization using Improved Discrete Particle Swarm Optimization (IDPSO)

R. S. Wadhwa[1], T. Lien[1], and G. Monkman[2]
[1]NTNU Valgrinda, Inst. for produksjons- og kvalitetstek., Trondheim, Norway
[2]FH Regensburg, Regensburg, Germany

The magnetic field gradient produced by an electromagnet gripper head depends on its design. Stochastic Methods offer certain robustness to the design optimization process. In this paper, Improved Discrete Particle Swarm Optimization (IDPSO) searching technique is applied to the shape and magnetic field gradient optimization of an electromagnet head. The magnetic field and forces are ...

Several Benchmarks for Heat Transfer Problems in COMSOL Multiphysics®

S. Titarenko[1]
[1]University of Leeds, Leeds, United Kingdom

Nowadays all branches in modern science and industry tend to solve ever complicating problems. As the result the computational time increases considerably and it become very important to reduce the processing time and use available resources more efficiently. Parallelizing problem proves itself as efficient way to overcome the described problem. In the poster we compare different methods of ...

Understanding Transport Phenomena Concepts in Chemical Engineering with COMSOL Multiphysics®

E. S. Vasquez [1],
[1] Department of Chemical and Materials Engineering, University of Dayton, Dayton, OH, USA

Transport Phenomena in Chemical Engineering involves three key aspects: Momentum, Heat and Mass Transport. These areas are described by differential equations which are solved for a particular problem using independent or a set of combined equations (e.g., water flowing in a heated pipe). At an undergraduate level class, the advanced mathematics of partial differential equations, tensors and the ...

COMSOL Multiphysics® Models Combined with Experiments to Teach PID Controller Tuning

W. Clark[1]
[1]Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

A laboratory exercise to learn PID controller tuning can be time consuming and taxing on the equipment. A purely equation-based, virtual controller tuning exercise might not seem relevant to real world processes. We have combined a physical process with a COMSOL Multiphysics model to teach the practical aspects of PID controller tuning. Students ran simulated experiments with COMSOL to test ...
