Transition to turbulence via 2-dimensional spatiotemporal intermittency in an electroconvective system of nematics

Abstract

The transition to turbulence via 2-dimensional spatiotemporal intermittency observed in an electroconvective system of nematics is investigated experimentally. The area fraction of total turbulent domain was continuously increased with control parameter. Dynamic hysteresis in the transition is found by measurements for various ramp rate r of the control parameter, and it is vanished for r → 0.
