Flow Statistics in the Transitional Regime of Plane Channel Flow
Pavan V. Kashyap, Yohann Duguet, Olivier Dauchot
The transitional regime of plane channel flow is investigated {above} the transitional point below which turbulence is not sustained, using direct numerical simulation in large dom…
Azimuthal instability of the radial thermocapillary flow around a hot bead trapped at the water-air interface
G. Koleski, A. Vilquin, J. -C. Loudet +2
We investigate the radial thermocapillary flow driven by a laser-heated microbead in partial wetting at the water-air interface. Particular attention is paid to the evolution of th…
The emergence of local wrinkling or global buckling in thin freestanding bilayer films
John F. Niven, Gurkaran Chowdhry, James S. Sharp +1
Periodic wrinkling of a rigid capping layer on a deformable substrate provides a useful method for templating surface topography for a variety of novel applications. Many experimen…
Structural transformations in tetravalent nematic shells induced by a magnetic field
Yoko Ishii, Ye Zhou, Kunyun He +4
The role of applied fields on the structure of liquid crystals confined to shell geometries has been studied in past theoretical work, providing strategies to produce liquid crysta…
