“…The experimental evidences considered as main ingredients of SOC are 1/f β (β >0) power law (where f is the frequency of the fluctuations obtained from Fast Fourier Transform) [10,11,12,13], long-range correlation [14], and nongaussian probability distribution function (PDF) [15]. From the power spectral analysis we have estimated the β from ln(Power) versus ln(f ).…”

Experimental observations consistent with Self Organized Criticality (SOC) have been obtained in the electrostatic floating potential fluctuations of a dc glow discharge plasma. Power spectrum exhibits a power law which is compatible with the requirement for SOC systems. Also the estimated value of the Hurst exponent (self similarity parameter), H being greater than 0.5, along with an algebraic decay of the autocorrelation function, indicate the presence of temporal long-range correlations, as may be expected from SOC dynamics. This type of observations in our opinion has been reported for the first time in a glow discharge system.Comment: Key Words: Glow discharge; Self Organized Criticality; Hurst exponent; R/S technique; Power spectrum; Autocorrelation function; Nongaussian probability distribution function.

“…Such fluctuations with a 1/f power spectrum were observed experimentally at nonequilibrium phase transitions in thermophysical systems: boiling crisis on a wire heater [7,8], explosive boiling-up of superheated liquid jets [9], ultrasonic cavitations [10], combustion [11], and electric discharge [12].…”

“…In past few years, the criticality of CHF is observed from a different respect. The critical phenomenon at boiling crisis is firstly reported by Skokov et al [15] by observing the current signal fluctuations with a 1/f spectrum on a vertical platinum wire heater. In 2010s, the Acoustic Emission(AE) energy distribution of heating surface in liquid nitrogen [16] and dry spot distribution in a slowed-down boiling of hydrogen at zero gravity [17] are also observed as critical phenomenon at boiling crisis.…”

Investigations of near-wall bubble behavior in wire heaters pool boiling

The current work establishes a pool boiling CHF prediction method based on percolation theory. For the first time, we observe the experimental bubble footprint?s power-law distributions with almost the same exponent in wire heaters? water pool boiling crisis, which is borne out strongly that boiling crisis is a typical continuum percolative scale-free behavior, and its characteristics seems not to be influenced by the critical heat flux value. The proposed one-dimensional Monte Carlo(MC) method successfully simulates the phase transition of interactive near-wall bubbles. This research enriches and extends applications of continuum percolation theory in boiling phenomena, and could be an instruction for the followed critical heat flux enhancement studies.
