Direct observation of twist mode in electroconvection in I52

, 2000
I report on the direct observation of a uniform twist mode of the director field in electroconvection in I52. Recent theoretical work suggests that such a uniform twist mode of the director field is responsible for a number of secondary bifurcations in ...

Coupled phenomena of concentration polarization in systems with anion-exchange membranes before and after their participation in electrodialysis of tartrate-containing solutions

Конденсированные среды и межфазные границы
Objective: Homogeneous anion-exchange membrane ASE and heterogeneous anion-exchange membrane MA-41P were investigated in 20±1 mM NaxH(2-x)T solutions with pH 2.5 and 9.0, where T represents the acid residue of tartaric acid.

Time-Dependent Diffusion Coefficients for Chaotic Advection due to Fluctuations of Convective Rolls

Fluids, 2018
The properties of chaotic advection arising from defect turbulence, that is, weak turbulence in the electroconvection of nematic liquid crystals, were experimentally investigated.

Pattern formation in annular convection

, 1998
This study of spatio-temporal pattern formation in an annulus is motivated by two physical problems on vastly different scales. The first is atmospheric convection in the equatorial plane between the warm surface of the Earth and the cold tropopause ...

Electroconvection in a Suspended Fluid Film: A Linear Stability Analysis

, 1996
A suspended fluid film with two free surfaces convects when a sufficiently large voltage is applied across it. We present a linear stability analysis for this system.

Temporal Modulation of the Control Parameter in Electroconvection in the Nematic Liquid Crystal I52

, 2000
I report on the effects of a periodic modulation of the control parameter on electroconvection in the nematic liquid crystal I52. Without modulation, the primary bifurcation from the uniform state is a direct transition to a state of spatiotemporal chaos.

Universal Fluctuations of Growing Interfaces: Evidence in Turbulent Liquid Crystals

, 2010
We investigate growing interfaces of topological-defect turbulence in the electroconvection of nematic liquid crystals. The interfaces exhibit self-affine roughening characterized by both spatial and temporal scaling laws of the Kardar-Parisi-Zhang ...
