Convection in Microemulsions

open access: yes, 1991
The Rayleigh-Benard convection in the microemulsion C4E2 (surfactant)-water-cyclohexane (oil) is presented from the onset of convection to the phase separation of the microemulsion. The travelling waves, steady convection, the transition from the roll pattern to the polygon pattern and the type-I intermittency route to chaos were observed and recorded ...

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

open access: yesAdvanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Continuous Structural Parameterization: A Proposed Method for Representing Different Model Parameterizations Within One Structure Demonstrated for Atmospheric Convection

open access: yesJournal of Advances in Modeling Earth Systems, 2020
Continuous structural parameterization (CSP) is a proposed method for approximating different numerical model parameterizations of the same process as functions of the same grid‐scale variables. This allows systematic comparison of parameterizations with

The Influence of Field‐Assisted Sintering Technology (FAST) Temperature and Cooling Rate on the Microstructural Evolution in Gamma‐Titanium Aluminide Alloy GE4822

open access: yesAdvanced Engineering Materials, EarlyView.
Controlling the Field Assisted Sintering Technology (FAST) parameters, dwell temperature and cooling rate, significantly influences the microstructural evolution in titanium aluminide GE4822. Significant γ‐lamellar colonies develop only upon cooling through the α‐transus.

The effect of Coriolis force on nonlinear convection in a porous medium

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
Nonlinear convection in a porous medium and rotating about vertical axis is studied in this paper. An upper bound to the heat flux is calculated by the method initiated first by Howard [6] for the case of infinite Prandtl number.

Versatile Pneumatic Twisted Coiled Actuators Enabled by Fiber‐Polymer Composite Fabrication

open access: yesAdvanced Functional Materials, EarlyView.
This work reports composite Pneumatic Twisted Coiled Actuators with embedded Kevlar fibers that convert pneumatic or hydraulic pressure into powerful linear motion. A novel precise manufacturing technique is used to systematically explore how design variables influence actuator mechanics and dynamics.

Lattice Boltzmann Method for Natural Convection in Anisotropic Porous Media

open access: yesJournal of Fluid Science and Technology, 2010
A lattice Boltzmann method (LBM) is proposed for the simulation of natural convection in anisotropic porous media with the generalized non-Darcy model. The Brinkman-Forchheimer momentum equation is recovered from a kinetic equation for the distribution ...
