[4]Instituto de Energías Renovables, Universidad Nacional Autónoma de México, Temixco, Morelos, México

Flows of electrically conducting liquids in external magnetic fields are present in several applications. In this kind of flow, the inhomogeneous magnetic field creates a breaking force on the conducting fluid. As a result, a stagnant zone is formed in the zone affected by the localized ... Mehr lesen

Numerical Investigation of Non-Newtonian Laminar Flow in a Curved Tube with Insert

A. Kadyyrov[1]
[1]Research Center for Power Engineering Problems, KSC, RAS, Russia

Non-Newtonian laminar flows in curved circular tubes with inserts are investigated by computer simulations. 0.65% solution of NaCMC is considered. Three-dimensional incompressible Navier-Stokes equations are solved using COMSOL Multiphysics. Placements of inserts inside the curved tubes ... Mehr lesen

FEA Simulation of Passive Ferrofluid Cooling Systems

[1]Pennsylvania State University, University Park, PA, USA
[2]Ferro Solutions Inc., Woburn, MA, USA
[3]Massachusetts Institute of Technology, Cambridge, MA, USA

Here we investigate a promising passive cooling method through making advantage of the unique properties of ferrofluid. When a magnetic dipole or a permanent magnet is put at the hot side of a system, it will attract the cold ferrofluid to the hot place and displace the hot ferrofluid ... Mehr lesen

[1] Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

Crack detection is and has been an active field of exploration, both theoretical and applied for a number of years. It is the belief of this author that the concepts presented herein explore a new methodology for the modeling and the detection of cracks and families of cracks in ... Mehr lesen

Reduction of Fluid Forces on a Square Cylinder Using Passive Control Methods

A. Alshayji [1], A. Abograis [1]
[1]Kuwait University, Kuwait City, Kuwait

COMSOL Multiphysics® is used in this study to simulate the flow around a square cylinder and focus on reducing the forces on the cylinder by passive control methods. Numerical simulations are made to find optimum cases of control methods that guarantee maximum reduction for Reynolds ... Mehr lesen

Simulations of Meniscus Motion and Evaporation for Convective Deposition Manufacturing

J. Xiao, and D. Attinger
Columbia University, New York, NY, USA

Convective deposition is a material processing technique where an evaporating meniscus of a colloidal suspension is dragged along a solid substrate to deposit layers of micro or nanoparticles. The process is a typical multiphysics process where fluid dynamics, mass and heat transfer come ... Mehr lesen

Electromagnetic Modeling of a Millimeter-Wavelength Resonant Cavity

[1] Battelle Memorial Institute, Norwell, MA, USA
[2] U.S. Department of Homeland Security, Science and Technology Directorate, Washington, DC, USA

The measurement of dielectric constant at frequencies of 20 GHz or greater is important for specifying the optical properties of materials at millimeter wavelength. One method of measurement uses a resonant cavity containing a sample of the material, and relates the resonant frequency ... Mehr lesen

Validation of COMSOL Multiphysics® for Magnetohydrodynamics (MHD) Flows in Fusion Applications

Y. Yan [1], S. Smolentsev [1], M. Abdou [1]
[1] Fusion Science and Technology Center, University of California, Los Angeles, CA, USA

Several commercial CFD companies have recently extended their codes to magnetohydrodynamic (MHD) flows. However, there are many computational challenges associated with MHD flows under the harsh fusion environmental conditions that require such codes to be carefully examined in a special ...
