Abstract: Abstract Space–time correlations of velocity and high-Schmidt-number ( $Sc \approx 2000$ ) passive scalar fields are investigated in turbulent pipe flow using particle image velocimetry and planar laser-induced fluorescence, respectively. Both the velocity and scalar… read more here.

Abstract: We investigate the effects of nonlinear stochastic interactions on hydrodynamic response functions. The interactions are parametrized by "stochastic transport coefficients" that are invisible in the classical constitutive relations, but nonetheless affect the late time hydrodynamic… read more here.
