Experimental characterization of vibrated granular rings
Z. A. Daya, E. Ben-Naim, R. E. Ecke
We report an experimental study of the statistical properties of vibrated granular rings. In this system, a linked rod and bead metallic chain in the form of a ring is collisionall…
Charge Transport Scalings in Turbulent Electroconvection
Peichun Tsai, Zahir A. Daya, Stephen W. Morris
We describe a local-power law scaling theory for the mean dimensionless electric current in turbulent electroconvection. The experimental system consists of a weakly conductin…
Codimension-two points in annular electroconvection as a function of aspect ratio
V. B. Deyirmenjian, Zahir A. Daya, Stephen W. Morris
We rigorously derive from first principles the generic Landau amplitude equation that describes the primary bifurcation in electrically driven convection. Our model accurately repr…
Aspect ratio dependence of charge transport in turbulent electroconvection
Peichun Tsai, Zahir A. Daya, Stephen W. Morris
We present measurements of the normalized charge transport or Nusselt number as a function of the aspect ratio for turbulent convection in an electrically driven film.…
Spontaneous spirals in vibrated granular chains
R. E. Ecke, Z. A. Daya, M. K. Rivera +1
We present experimental measurements on the spontaneous formation of compact spiral structures in vertically-vibrated granular chains. Under weak vibration, when the chain is quasi…
Sequential Bifurcations in Sheared Annular Electroconvection
Zahir A. Daya, V. B. Deyirmenjian, Stephen W. Morris
A sequence of bifurcations is studied in a one-dimensional pattern forming system subject to the variation of two experimental control parameters: a dimensionless electrical forcin…
