Global Stability For Double-Diffusive Convection In A Couple-Stress Fluid Saturating A Porous Medium

Studia Geotechnica et Mechanica, 2019
We show that the global non-linear stability threshold for convection in a double-diffusive couple-stress fluid saturating a porous medium is exactly the same as the linear instability boundary.

Machine Learning‐Assisted Inverse Design of Soft and Multifunctional Hybrid Liquid Metal Composites

Advanced Functional Materials, EarlyView.
A machine learning framework is presented for inverse design of synthesizable multifunctional composites containing both liquid metal and solid inclusions. By integrating physics‐based modeling, data‐driven prediction, and Bayesian optimization, the approach enables intelligent design of experiments to identify optimal compositions and realize these ...

Marangoni convection in a double diffusive binary fluid with temperature dependent viscosity, Coriolis force and internal heat generation [PDF]

, 2019
A steady Marangoni convection in a horizontal double diffusive binary fluid is considered. Present study investigated the effects of temperature dependent viscosity, Coriolis force and internal heat generation to the onset of convection.

Janus Photonic Graphics by Stratified Assembly of Two Distinct Colloids

Advanced Functional Materials, EarlyView.
Double‐sided Janus photonic micropatterns with vivid structural colors are fabricated through a single‐step bottom‐up strategy. Density‐driven stratification and depletion‐mediated crystallization of PMMA and PS binary colloids lead to exclusive lattices on opposite surfaces under centrifugal force.

Study of heat and mass transport in Couple-Stress liquid under G-jitter effect

Ain Shams Engineering Journal, 2018
In the present paper, we deal with the effect of G-jitter (time periodic gravity modulation) on the stability of double diffusive convection in couple stress liquid by method of non-linear analysis. The infinitesimal disturbances are expanded in terms of

DOUBLE-DIFFUSIVE CONVECTION IN LIQUID FREON

Proceeding of International Heat Transfer Conference 11, 1998
When a fluid initially stratified by a vertical variation of species concentration is heated from a sidewall, the classic thermal convection could be dramatically altered by the stable gradient of mass. The convection starts near the heated wall but it is then limited to "convective cells" separated by diffusive interfaces with sharp variation of ...

Convection in fluid and porous media [PDF]

, 2003
The subject of convection in fluid and porous media is investigated. Particular attention is paid to penetrative convection. The first two chapters are devoted to penetrative convection when fluid overlies and saturates a porous medium.

The effect of temperature-dependent solubility on the onset of thermosolutal convection in a horizontal porous layer

, 2007
We consider the onset of thermosolutal (double-diffusive) convection of a binary fluid in a horizontal porous layer subject to fixed temperatures and chemical equilibrium on the bounding surfaces, in the case when the solubility of the dissolved ...
