ABSTRACT
It is shown that in the framework of the weak turbulence theory, the autocorrelation and cascade time scales are always of the same order of magnitude. This means that, contrary to the general belief, any model of turbulence that implies a large number of collisions among wave packets for an efficient energy cascade (such as the Iroshnikov–Kraichnan model) is not compatible with the weak turbulence theory.

    An analysis is made of the Lagrangian and the Eulerian velocity autocorrelations RL(s,t) and RE(s,t) at times s and t for small time lag τ=s-t in isotropic decaying turbulence, and it is shown that under appropriate conditions RE≤RL for small τ in three dimensions, irrespective of...

    When performing wind integration studies, synthetic wind power forecasts are key elements. Historically, data from operational forecasting systems have been used sparsely, likely due to the high costs involved. Purely statistical methods for simulating wind power forecasts are more common, but...

    We have developed a low-cost rapid-scanning autocorrelator which enables us to monitor picosecond optical pulses up to almost 100 ps. To achieve wide-scan range, each arm of a Michelson-type interferometer is scanned 180° out of phase by using audio speakers, and also only one-half of a full...

    Eddy covariance data are increasingly used to estimate parameters of ecosystem models. For proper maximum likelihood parameter estimates the error structure in the observed data has to be fully characterized. In this study we propose a method to characterize the random error of the eddy...

    The dynamic velocity range of particle image velocimetry (PIV) is determined by the maximum and minimum resolvable particle displacement. Various techniques have extended the dynamic range, however flows with a wide velocity range (e.g., impinging jets) still challenge PIV algorithms. A new...
