Chaotic Behavior of the Airflow in a Ventilated Room

A.W.M. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

Chaotic systems may lead to instability, extreme sensitivity and performance reduction. Therefore it is unwanted in many cases. Due to these undesirable characteristics of chaos in practical systems, it is important to recognize such a chaotic behavior. The existence of chaos has been ... En savoir plus

COMSOL in the Academic Environment at USNA

K. Mcilhany[1], and R. Malek-Madani[2]
[1]Department of Physics U. S. Naval Academy, Annapolis, Maryland, USA
[2]Department of Mathematics, U. S. Naval Academy, Annapolis, Maryland, USA

The U.S. Naval Academy has used COMSOL as a research tool for many years. Academic usage of COMSOL for student use has only begun in the last five years. Student involvement comes in four types, course-wide usage, focused course related work, student projects and semester-long research ... En savoir plus

Modeling the Bacterial Clearance in Capillary Network Using Coupled Stochastic-Differential and Navier-Stokes Equations

A. Atalla[1], and A. Jeremic[1]
[1]McMaster University, Hamilton, Ontario, Canada

The capillary network is a complex-interconnected structure. A single blood cell traveling from the arteriole to a venule via a capillary bed passes through, on average, 40−100 capillary segments. The cardiovascular systems responsible of delivering blood to the tissue under sufficient ... En savoir plus

Definition of Optimization Problem for Electromagnetic Linear Actuator

P. Piskur[1], W. Tarnowski[1], and K. Just[1]

[1]Koszalin Technical University, Koszalin, Poland

In this paper a poly-optimization of the design of the electromechanical actuator is presented. The shape of the actuator is defined by the decision variables. The number of decision variables under consideration is up to ten but in the next step while the multi-coils system will be ... En savoir plus

Handling Tessellated Free Shape Objects with a Morphing Mesh Procedure in COMSOL Multiphysics^®

P. Franciosa[1] and S. Gerbino[2]
[1]Faculty of Engineering, University of Naples Federico II, Napoli, Italy
[2]Faculty of Engineering, University of Molise, Campobasso, Italy

Tessellated models are more and more used in several engineering fields. The need to use such models to quickly perform computer simulations related to coupled physical phenomena, implies the use of dedicated software, allowing to solve, into an integrated environment, multiphysics ...
