The probability distribution of each time-series dataset exhibits deterministic correlations with contrasting entropy process regions afterglow (blown arc process (gap = 0.5 cm and 1740 ±100 K); and gap = 1 to 7 cm and 300 to 400 K)). The results indicate that the heated air is channeled along the surface and has a preferred backscatter an ular. In addition the blown arc process exhibits a skewness of +0.055 and the afterglow has skewness values from -0.05 to -0.4. These results illustrate how acoustic information can be used to differentiate plasma-surface entropy states.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||American Institute of Physics||Copyright (published version):||2011 American Institute of Physics||Keywords:||Acoustic noise;Atmospheric plasma jet;Acoustic intensity||DOI:||10.1063/1.3637773||Language:||en||Status of Item:||Not peer reviewed||Conference Details:||NUMERICAL ANALYSIS AND APPLIED MATHEMATICS ICNAAM 2011: International Conference on Numerical Analysis and Applied Mathematics, 19–25 September 2011, Halkidiki, (Greece)|
