When Precise Numerical Predictions Come to the Rescue of Liquid Lubrication

J. D. Wheeler [1], V. Bruyere [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Whereas some bearings designed in the 19th century are still working properly nowadays, some others which were recently designed encountered premature failures. Tribological applications, such as journal bearings or rolling element bearings, are generally ruled by complicated ... En savoir plus

Elucidating the Mechanisms of Charge and Temperature Modulated Ionic Transport in Nanochannels

G. Zhang [1], Y. Zhao [1],
[1] Department of Biomedical Engineering, University of Kentucky, Lexington, KY, USA

The transport of fluid through nanochannels is of importance in a variety of technological applications, including biological sensing, energy storage and conversion, chemical separation and many others. Synthetic nanofluidic architectures that mimic the gating functions of biological ion ... En savoir plus

Analyzing Fluid Shear Stress in the RCCS: Applications for 3D Cell Culture in Simulated Microgravity

T. Masiello [1], A. Dhall [1], L. P. Madhubhani Hemachandra [1], N. Tokranova [1], J. Castracane [1]
[1] Colleges of Nanoscale Science and Engineering, SUNY Polytechnic Institute, Albany, NY, USA

In the decades since humans first went to space, there has been growing interest in utilizing microgravity to improve our understanding in many scientific fields (1). Applied fields have included evolutionary development, cell mechanics and protein crystallization (2-4). Microgravity ... En savoir plus

Adaptive Mesh Refinement: Quantitative Computation of a Rising Bubble Using COMSOL Multiphysics®

T. Preney [1], P. Namy [1], J. Wheeler [1]
[1] SIMTEC, Grenoble, France

The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... En savoir plus

The Effect of Aluminum Content on Convective Flow of Molten Metal Generated by Arc Plasma

Y. T. Cho [1], C. K. Kim [1], H. U. Hong [1],
[1] Changwon National University, Changwon, Gyeongsangnam-do, South Korea

Arc plasma can heat and melt the metal material and flows of molten metal can be affected by several forces such as Lorentz force which is ruled by current, Marangoni force controlled by surface tension, buoyancy force, and arc drag force. Usually, surface tension variation is determined ... En savoir plus

Several Hydrodynamic Instabilities Illustrated Using the COMSOL Multiphysics® Software

C. F. Ivory [1],
[1] Washington State University, Pullman, WA, USA

The COMSOL Multiphysics® software has proved itself an invaluable tool for teaching "Transport Phenomena" to graduate and undergraduate engineers. In particular, the software allows us to visualize and explore solutions well beyond what students could do with pencil and paper. For ... En savoir plus

Resonance Frequency of a Helmholtz Resonator

R. Hill [1], M. Mendieta [1], P. Bruce [1], E. Stokes [1]
[1] Electrical and Computer Engineering Department, University of North Carolina - Charlotte, Charlotte, NC, USA

Acoustic metamaterials commonly use Helmholtz resonators to attenuate an acoustic signal at the resonator’s resonance frequency. The resonance frequency is only dependent on the geometry, which is shown by representing the Helmholtz resonator as a mass spring system using the lumped ... En savoir plus

Process Intensification Efforts towards Efficient, Modular, Solar-Thermochemical Production of Liquid Fuels

L. Freiberg [1], M. Coblyn [1], G. Jovanovic [1], N. AuYeung [1],
[1] Oregon State University, Corvallis, OR, USA

Concerning the reduction of fossil-energy use from industrial processes, power generation and transportation, concentrated solar power from dish reflectors is well suited for driving highly endothermic reactions that valorize CO2 and/or light hydrocarbons. In this study, a directly ... En savoir plus

Modeling a Concentrated Solar Thermal Collector for Methane Dry Reforming

S. Verma [1], N. Hotz [1],
[1] Duke University, Durham, NC, USA

Hydrogen has great potential to be the fuel of the future through utilization in fuel cells, but it is rarely found naturally and must be produced in energy-intensive processes. Steam reforming, the process of heating natural gas and steam in the presence of a catalyst to drive a ... En savoir plus

Magnetic Control of Deformation of a Ferrofluid Droplet in Simple Shear Flow

C. Wang [1], M. R. Hassan [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study investigates the effect of uniform magnetic field on the deformation of a ferrofluid droplet in a two dimensional (2D) simple shear flow by means of numerical simulation. The magnetic field is applied in a perpendicular direction to the flow direction. A numerical scheme ... En savoir plus
