TL;DR: In this article, a detailed quantitative analysis is made of the suggestion that the observed presence of a well-defined large-scale pattern of the temperature signal in these flows is responsible for this breakdown.

TL;DR: In this paper, two circular jets are considered, one issues from a contraction with a laminar top-hat velocity profile and the other exits from a pipe with a fully developed turbulent mean velocity profile.

TL;DR: In this article, the evidence for and against local isotropy is assessed in the light of measurements in a turbulent plane jet at moderate values of the Reynolds and Peclet numbers, including spatial derivatives with respect to different spatial directions of the longitudinal velocity fluctuation and of the temperature fluctuation.

TL;DR: In this paper, the authors examined experimental (boundary layer) and direct numerical simulation (channel flow) data for the invariants of the Reynolds stress tensor and found that roughness reduces the level of anisotropy relative to a smooth wall.

TL;DR: In this article, the relationship between the fluctuating velocity vector and the temperature fluctuation has been examined using direct numerical simulation databases of a turbulent channel flow with passive scalar transport using a constant time-averaged heat flux at each wall for h + = 180, 395, 640 and 1020 (where h is the channel halfwidth with the superscript denoting normalization by wall variables) at Prandtl number Pr = 0.71.
