E × B shear pattern formation by radial propagation of heat flux waves

E × B shear pattern formation by radial propagation of heat flux wavesa)

How the propagation of heat-flux modulations triggers E × B flow pattern formation.

We propose a novel mechanism to describe E×B flow pattern formation based upon the dynamics of propagation of heat-flux modulations. The E × B flows of interest are staircases, which are quasiregular patterns of strong, localized shear layers and profile corrugations interspersed between regions of avalanching. An analogy of staircase formation to jam formation in traffic flow is used to develo...

Effect of Micropolarity on the Propagation of Shear Waves in a Piezoelectric Layered Structure

This paper studies the propagation of shear waves in a composite structure consisting of a piezoelectric layer perfectly bonded over a micropolar elastic half space. The general dispersion equations for the existence of shear waves are obtained analytically in the closed form. Some particular cases have been discussed and in one special case the relation obtained is in agreement with existing r...
