Application for Simulating Acoustic Response of Condenser Microphone Cartridges

Jason Cillo¹
¹Shure Inc - Niles, IL

Electret condenser microphones are one of the most used transducers for a variety of applications. The engineer designing these cartridges must take into consideration many factors to create a design that meets its specifications. Most parts of the design have multiple constraints across ...

Microalgae Cell Separation and Concentration in a Microfluidic Channel Under Dielectrophoresis (DEP) Effect

A. Barai[1], N. Boldt[2], M. Birkholz[1]
[1]IHP - Leibniz-Institut für innovative Mikroelektronik, Germany
[2]Technische Universität Berlin, Germany

Microalgae biomass is an essential part of the global ecosystem. Not only is it responsible for 50% of the global oxygen but also proved to be useful in the development of organic polymers, antioxidants, pharmaceuticals, and feedstocks for aquatic animals. It is considered as an ... En savoir plus

Simulation of Highly Nonlinear Electrokinetics Using a Weak Formulation

G. Soni[1], T. Squires[2], and C. Meinhart[1]

[1]Department of Mechanical Engineering, University of California Santa Barbara, CA, USA
[2] Department of Chemical Engineering, University of California Santa Barbara, CA, USA

We present a numerical model for simulating highly nonlinear electrokinetic phenomena, which occurs at high zeta potentials. In this model, the electric double layer is realized by solving a partial differential equation (PDE) on the double-layer-inducing surface. We also allow for a ... En savoir plus

A Numerical Investigation on Active Chilled Beams for Indoor Air Conditioning

G. Cammarata, and G. Petrone
Department of Industrial and Mechanical Engineering, University of Catania, Catania, Italy

In this study fluid-dynamical and thermal performance of active chilled beams is investigated by 2D and 3D modelling in COMSOL Multiphysics. Three different typologies of those air conditioning systems are considered. Results, obtained for typical range of variation of operational ... En savoir plus

Comparison of an Analytical and Numerical Solution for the Landmine Detection Problem

M. Mattingly[1], K. McIlhany[2], and R. Malek-Madani[3]

[1]Applied Research Laboratory, The Pennsylvania State University, University Park, PA, USA
[2]Physics Department, United States Naval Academy, Annapolis, MD, USA
[3]Mathematics Department, United States Naval Academy, Annapolis, MD, USA

Acoustic landmine detection is accomplished using a loud speaker as an airborne source to generate low-frequency waves that enter the soil at a certain incident angle. At a specific frequency, the landmine will "vibrate" at resonance, imparting a certain velocity on the soil particles ... En savoir plus

Iberian COMSOL Multiphysics Conference 2024

In this conference we have brought together a community that is scientifically diverse in an event that allows for inspiring contacts about the use of COMSOL Multiphysics. It is an event to connect with the Spanish and Portuguese COMSOL Multiphysics users and participate in training ... En savoir plus

Equation-Based Modeling: Simulation of a Flow with Concentrated Vorticity in an Unbounded Domain

J. M. Russell [1],
[1] Florida Institute of Technology, Melbourne, FL, USA

The velocity field of a fluid flow in an unbounded domain, R, in which the spin of fluid elements is nonzero only within a bounded subdomain, Ri---namely, the interior of a sphere of radius, a---is simulated by equation-based modeling. A change of independent variable motivated by Kelvin ... En savoir plus

Modeling On-Chip Nanoscale Trap and Enhance Device for Quantum Photonics Using COMSOL Multiphysics®

S. Saha¹, N. Kinsey¹
¹Virginia Commonwealth University, Richmond, VA, USA

In recent years, with the rise of quantum optical technologies, there has been a spurring research interest growing on single-photon emitters (SPE). To date, the focus in engineering improved SPE has been mainly towards better enhancement overlooking the tenuous manufacturing process ... En savoir plus

Virtual Prototyping of UV-LED Based Point-of-Use Water Disinfection Unit

P. V. Christensen [1], P. Juul [2],
[1] Virtual Water Technology, Silkeborg, Denmark
[2] Liqtech Systems, Hobro, Denmark

Water disinfection using UV light is a well-known technology. Conventionally, mercury based cylindrical lamps are used, however, recently LED based UV lamps have emerged on a commercial scale. These devices hold several advantages compared to the conventional lamps, e.g. being mercury ... En savoir plus

Investigation of the Flow Characteristics of an Aerosol Mixing Facility

S. Horender [1], K. Auderset [1], K. Vasilatou [1],
[1] METAS, Bern, Switzerland

The measurement and regulation of particulate matter to improve outside air quality advanced a lot over the last decades. This also made it necessary to develop primary standards for calibrating these measurement systems and in future the composition of relevant aerosols will be taken ... En savoir plus
