Ultrasound-assisted Microfluidic Devices: Insights and Optimization of Sono-microreactors

F. J. Navarro-Brull [1], P. Poveda [2], J. Ramis [2], R. Gómez [1],
[1] Departament de Química Física, Universidad de Alicante, Alicante, Spain
[2] Departament de Física, Enginyeria de Sistemes i Teoria del Senyal, Universidad de Alicante, Alicante, Spain

Possible drawbacks of microreactors are inefficient reactant mixing due to the predominance of laminar flow and clogging (when solid-forming reactions are performed or solid catalyst suspensions are used). Ultrasound has been successfully implemented not only to prevent these problems ... En savoir plus

PA Loudspeaker System Design Using Multiphysics Simulation

R. Balistreri [1],
[1] QSC Audio Products, LLC., Costa Mesa, CA, USA

This paper utilizes lumped circuits equivalent and pressure acoustics to simulate the behavior of a PA loudspeaker in order to improve its design. En savoir plus

PVDF Piezoelectric Nanofibers as Hair Cell Substitutes: A Feasibility Study

C. R. Pérez [1], J. J. Santiago-Avilés [2],
[1] Department of Materials Science and Engineering, University of Pennsylvania, Philadelphia, PA, USA
[2] Department of Electrical and Systems Engineering, University of Pennsylvania, Philadelphia, PA, USA

Sensorineural hearing loss is the most common sensory deficit in the world, and within this category damage or loss of the primary sensory cells of the inner ear, known as hair cells is the most common cause [1]. Partial hearing loss is addressed by the use of hearing aids, electronic ... En savoir plus

A Lesson in Cartilage Therapy: Do Chondrocytes Utilize Mechanical Energy from Exercise for Cell Maintenance and Growth?

A. Miller [1], H. Viljoen [1], A. Chama [2], T. Louw [2],
[1] Department of Chemical and Biomolecular Engineering, University of Nebraska - Lincoln, Lincoln, NE, USA
[2] Department of Chemical Engineering, Stellenbosch University, Stellenbosch, South Africa

Using COMSOL Multiphysics® Acoustics Module: Chondrocytes modeled attached to a plane (to mimic in vivo constraints) are shown to resonate near 5MHz. At resonance, the mechanical energy density in the nucleus is two times higher than in the cytoplasm. Impact exercise is modeled as ... En savoir plus

The Effect of Resistance on Rocket Injector Acoustics

C. J. Morgan [1], S. R. Fischbach [1],
[1] Jacobs ESSSA Group, NASA Marshall Space Flight Center, Huntsville, AL, USA

This study evaluates the effect of injector resistance on the mode shapes and complex eigenfrequencies of an injector/combustion chamber system by defining a high Mach-flow, potential flow form of the convective wave equation in the Coefficient Form PDE Mathematics interface. Background ... En savoir plus

Infrasound Assessment of the Roller Compacted Concrete Dam: Case Study of the Portugues Dam in Ponce, PR

H. Diaz-Alvarez [1], V. P. Chiarito [1], S. McComas [1], M. H. McKenna [1],
[1] U.S. Army Engineer Research and Development Center, Vicksburg, MS, USA

The U.S. Army Corps of Engineers is currently investigating the use of infrasound sensors to monitor the health of structures of interest. Infrasound is low-frequency (2-20 Hz) acoustic energy and is capable of propagating many kilometers from the source structure. Large infrastructure, ... En savoir plus

Advanced Topics in Acoustics Simulation

M. J. Herring Jensen [1]
[1] COMSOL A/S, Lyngby, Denmark

In this session, we will discuss and showcase a few examples of advanced acoustics applications. In this context, “advanced” means problems that cannot simply be modeled “out-of-the-box,” but require the flexibility and strengths of COMSOL Multiphysics® software. Topics include: • ...

Solid Rocket Motor Combustion Instability Modeling in COMSOL Multiphysics® Software

S. R. Fischbach [1][2],
[1] Jacobs ESSSA Group, NASA Marshall Space Flight Center, Huntsville, AL, USA
[2] Qualis Corporation, Huntsville, AL, USA

Combustion instability modeling of Solid Rocket Motors (SRM) remains a topic of active research. Many rockets display violent fluctuations in pressure, velocity, and temperature originating from the complex interactions between the combustion process, acoustics, and steady-state gas ...
