MHD Electrolyte Flow within an Inter-electrode Gap Driven by a Sinusoidal Electric Field and Constant Magnetic Field

C. Bradley [1], J. Samuel [2],
[1] Benét Laboratories, U.S. Army RDECOM-ARDEC, Watervliet, NY, USA
[2] Department of Mechanical Aerospace and Nuclear Engineering, Rensselaer Polytechnic Institute, Troy, NY, USA

PECM is a necessary extension to traditional ECM for some high-performance materials. Electrolyte flow in the inter-electrode gap (IEG) can be assisted using a magnetic field to allow higher currents, but this creates a magnetohydrodynamic flow. This paper presents a study of flow ...

Investigation of Natural Convective Air Flow Field through Comb Channels

R. Umhack, M. Rainer, M. Tamerle, and G. Hillmer
Process-, Environmental- and Bio- technology, MCI - University of Applied Sciences, Innsbruck, Austria

A new type of radiator with a package of combs, to gain a larger area for heat exchange, instead of trapezoidal convector plates, is investigated. The main aim is to find the optimal comb diameter. To solve this problem, CFD (computational fluid dynamics) with COMSOL Multiphysics is ... En savoir plus

3-D Modeling of Light, Flow, Mass and Heat Transfer in Coral Colonies

Martinez Jimenez Fernan David¹, Murthy Swathi², Picioreanu Cristian¹, Kühl Michael²
¹King Abdullah University of Science and Technology (KAUST), Water Desalination and Reuse Center, Biological and Environmental Science and Engineering Division, Thuwal 23955-6900, Saudi Arabia
²Marine Biology Section, Department of Biology, University of Copenhagen, Strandpromenaden 5, 3000 Helsingør, Denmark

Corals are symbiotic marine organisms greatly dependent on the dynamic gradients of light, temperature and chemical species, all affected by the water flow in their surroundings. We developed a multiphysics modelling approach to simulate the microscale spatial distribution of light, ... En savoir plus

Effect of Interfacial Charge on the Drop Deformation under the Application of Oscillatory Electric Field.

R. Patil[1], and V. A. Juvekar[1]
[1] Department of Chemical Engineering, Indian Institute of Technology Bombay, Maharashtra

Study of interaction of drops and bubbles with electric field is important for understanding the physics involved in various physical phenomenas and industrial processes. Important applications arise in colloidal systems (Miller and Scriven, 1970), meteorology and cloud physics (Sartor, ... En savoir plus

Study of Impact of Terrain Structure on the Dispersion of Accidentally Released Air Pollutants

Sk. Moumita Manjur¹, Sidney Lin¹
¹Lamar University, Beaumont, TX, U.S.A.

Toxic and hazardous air pollutants are released during chemical processes. The surrounding area of a chemical facility always has a high risk of air pollution by released chemicals. Furthermore, the personnel of the facility as well as community residents have risks of sudden ... En savoir plus

Modelling Thermal Time-of-Flight Sensor for Flow Velocity Measurement

O. Ecin[1], E. Engelien[2], M. Malek[2], R. Viga[2], B. Hosticka[1], and A. Grabmaier[2]

[1]Institut of Mikroelektronische Systeme, University Duisburg-Essen, Duisburg, Germany
[2]Institut of Elektronische Bauelemente und Schaltungen, University Duisburg-Essen, Duisburg, Germany

This communication reports on a numeric fluid dynamics simulation on a pipe flow model. The basic background is to determine the velocity of a flowing fluid in a pipe by using the Thermal Time-Of-Flight (TTOF) method on water. The visualization of the temperature and velocity ... En savoir plus

Electrothermoplasmonic Flow in Gold Nanoparticle Suspensions

Emilio Ruiz-Reina¹, Carlos David Gónzalez-Gómez¹, Raúl A. Rica²
¹University of Málaga, Málaga, Spain
²University of Granada, Granada, Spain

Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient leads to a strong electrothermal flow that can be used for multiple purposes. Combining simulations and ... En savoir plus
