Lifetime estimate for plasma turbulence
A method is proposed to experimentally determine the intrinsic time scale or a decay rate of turbulent fluctuations. The method is based on the assumption that the Breit-Wigner spectrum model with a non-Gaussian frequency broadening is valid in the data analysis. The decay rate estimate is applied to the multi-spacecraft magnetic field data in interplanetary space, yielding that the result that...
متن کاملInteractive comment on “ Lifetime estimate for plasma turbulence ” by Yasuhito Narita and Zoltán Vörös
• In this innovative paper the authors introduce the Breit-Wigner spectral distribution function in order to fit the observed data and extract the underlying turbulence decay rate. I believe that this is a worthwhile approach that should be made aware to the space physics community in general, since this method may be useful for unraveling some underlying physical processes. I have some questio...
متن کاملEstimate the Performance of Catalytic Converter Using Turbulence Induce Devices
In this manuscript, the experimental setup was designed and fabricated for optimizing the parameters of a catalytic converter of INDICA V2 exhaust system. Three turbulence intensify devices, namely Swirl Venturi, Swirl Blades and Swirl Contour, were close-fitted before the catalytic converter. The heating element is embedded in its body and thermocouples are used for knowing the performance at ...
متن کاملGeneral Estimate for the Graviton Lifetime
By means of general kinematical arguments, the lifetime τ of a graviton of energy E for decay into gravitons is found to have the form τ = 1 EG ∑ j=1,2,... cj(ΛG) j . Some recent, preliminary results of non perturbative simplicial quantum gravity are then employed to estimate the effective values of G and ΛG. It turns out that a short lifetime of the graviton cannot be excluded. The recent adva...
متن کاملIntermittency in Plasma Turbulence
Intermittency in fluid turbulence can be evidentiated through the analysis of Probability Distribution Functions (PDF) for velocity fluctuations, which display a strong non–gaussian behavior at small scales. In this paper we investigate the occurrence of intermittency in plasma turbulence by studying the departure from the gaussian distribution of PDF for both velocity and magnetic fluctuations...
