Analyzing a turbulent pipe flow via the one-point structure tensors: Vorticity crawlers and streak shadows
(2016)Efforts to identify and visualize near-wall structures typically focus on the region y+≳5, where large-scale structures with significant turbulent kinetic energy content reside, such as the high-speed and low-speed streaks ...

The contribution of active and inactive structures to the statistics of a turbulent pipe flow
(2017)The current study is a short follow-up to our most recent work (Stylianou et al., 2016), where among other things we have presented an effective criterion suitable for distinguishing large-scale coherent structures with ...

A general framework for computing the turbulence structure tensors
(2015)Good measures of the turbulence structure are important for turbulence modeling, flow diagnostics and analysis. Structure information is complementary to the componentality anisotropy that the Reynolds stress tensor carries, ...

Representing anisotropy of two-point second-order turbulence velocity correlations using structure tensors
(2008)A locally homogeneous representation for the two-point, second-order turbulent velocity fluctuation Rij(x,r) = 〈u′i(x)u′i(x+r)〉 is formulated in terms of three linearly independent structure tensors [Kassinos et al., J. ...
