The behaviour of fluid-particle acceleration in near-wall turbulent flows is investigated in numerically simulated turbulent channel flows at low to moderate Reynolds numbers, Reτ =180∼ 600. The acceleration is decomposed into pressure-gradient (irrotational) and viscous contributions (solenoidal acceleration) and the statistics of each component are analysed. In near-wall turbulent flows, the ...
It is reported that the characteristic relations of type-II and type-III intermittencies, with respective local Poincaré maps of xn+1 = (1+ǫ)xn+ax 3 n and xn+1 = −(1 + ǫ)xn − ax3n, are both −ln(ǫ) under the assumption of uniform reinjection probability. However, the intermittencies have various characteristic relations such as ǫ−ν (1/2 ≤ ν ≤ 1) depending on the reinjection probability. In this ...
Visual feedback and non-visual information play different roles in tracking of an external target. This study explored the respective roles of the visual and non-visual information in eleven healthy volunteers who coupled the manual cursor to a rhythmically moving target of 0.5 Hz under three sensorimotor conditions: eye-alone tracking (EA), eye-hand tracking with visual feedback of manual outp...
A randomization test was developed to determine the statistical significance of QCD intermittency in single-event distributions. A total of 96 simulated intermittent distributions based on standard normal Gaussian distributions of size N=500, 1000, 1500, 2000, 4000, 8000, 16000, and 32000 containing induced holes and spikes were tested for intermittency. Non-intermittent null distributions were...
