Numerical Simulations of Spherical Gap Flows

K. Buehler, and J. W. Louw
University of Applied Sciences Offenburg, Germany

Rotating fluids are important in nature and technology. Many applications can be found in the field of meteorology and in rotating machinery. This investigation concerns the application of the swirl flow application mode in COMSOL Multiphysics to simulate nonlinear aspects of flows ... Read More

COMSOL Multiphysics Simulations of Microfluidic Systems for Biomedical Applications

M. Dimaki, J. Moresco Lange, P. Vazquez, P. Shah, F. Okkels, and W. Svendsen
Department of Micro- and Nanotechnology, Technical University of Denmark, Lyngby, Denmark

The need for fast, easy and cost-effective analysis of blood samples as well as our understanding of the functionality of cells and neurons are two rather pressing issues in the modern world. Both of these can be addressed by functional lab-on-a-chip systems, which have been designed and ... Read More

Statistics of Numerical Experiments with Multi-Fracture Systems

E. Holzbecher¹
¹German University of Technology, Halban, Oman

Modeling of fractured porous media systems is currently of high interest in various academic and applied fields, mainly in the geological and material sciences. The very different scales of the region of an application case on the larger end and the fracture on the lower end pose a ... Read More

Cellular Convection in Vertical Annuli at roof slab of Fast Breeder Reactor

M. G. Hemanath[1], C. Meikandamurthy[1], G. Padmakumar[1], C. A. Babu[1], P. Kalyanasundaram[1], and G. Vaidyanathan[1]
[1] Fast Reactor Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu, India

In the pool type Fast Breeder Reactors the roof structure is penetrated by a number of pumps and heat exchangers which are cylindrical in shape. Argon gas in reactor is sandwiched between the free surface of sodium and the roof structure and can flow in the annular space between the ... Read More

Simulating Microbubble Flows Using COMSOL Multiphysics

X. Chen[1], and S. Ghadiali[1,2]

[1]Mechanical Engineering and Mechanics, Lehigh University, Bethlehem, PA, USA
[2]Bio Engineering program, Lehigh University, Bethlehem, PA, USA

Acute respiratory distress syndrome (ARDS) is a severe lung disease caused by a variety of direct and indirect insults. The main treatment for ARDS is mechanical ventilation. The ventilation of fluid filled lungs involves the propagation of microbubbles over a layer of epithelial cells. ... Read More

Using COMSOL Multiphysics for Modeling of Musculoskeletal Biomechanics

R. L. Spilker
Department of Biomedical Engineering, Rensselaer Polytechnic Institute, New York, USA

In this presentation, we study the modeling of physiology and muscoskeletal biomechanics using COMSOL. The outline for the presentation is in particular: Why is COMSOL particularly powerful for modeling physiology? Modeling soft tissues like cartilage Optimization to determine soft ... Read More

Numerical Calculation of Effective Density and Compressibility Tensors in Periodic Porous Media: A Multi-Scale Asymptotic Method

C. Lee[1], M. Leamy[1], and J. Nadler[2]

[1]School of Mechanical Engineering, Georgia Institute of Technology, Atlanta, GA, USA
[2]Georgia Tech Research Institute (GTRI), Georgia Institute of Technology

A major issue in predicting and controlling (via design) absorption properties of rigid porous media is the determination of the frequency-dependent effective density and compressibility tensors. Unlike previous research efforts which employ in-house and, oftentimes, multiple numerical ... Read More

Effect of Conductivity and Viscosity in the Velocity Characteristics of a Fluid Flow Induced by Nonuniform AC Electric Field in Electrolytes on Microelectrodes

P. Parikh[1], A. Sethi[1], S. Benedict[1], D. N. Prasad[1], B. Mallik[2], S. Kapur[1], S. Deb[1], S. Banerjee[1]
[1]BITS Pilani Hyderabad Campus, Hyderabad, Andhra Pradesh, India
[2]Megnadh Saha Institute of Technology, Kolkata, India

Electrokinetic transport of fluids has been investigated both experimentally and numerically due to its various applications in microfluidic devices [1-5]. These devices offer the advantage of transporting fluids or particles to specific locations without the aid of mechanical ... Read More

Fluidmechanical Damping Analysis of Resonant Micromirrors with Out-of-plane Comb Drive

T. Klose[1], H. Conrad[2], T. Sandner[1], and H. Schenk[1]

[1]Fraunhofer Institute Photonic Microsystems (FhG-IPMS), Germany
[2]TU Dresden, Semiconductor and Microsystems Technology Laboratory, Germany

Damping is the liminting factor for the reachable maximum deflection. Thus, it is a very important issue for resonant microsystems. In this paper, we present a damping model for out-of-plane comb driven resonant micromirrors. The basic concept of this model is to attribute viscous ... Read More
