Transpiration cooling in gas turbines: mixing & interaction with cold film

Inter-scale exchanges in turbulent boundary layers above urban canopies
(LHEEA / Centrale Nantes)
Extracted from Basley, Perret & Mathis, Spatial Modulation of kinetic energy in the roughness sublayers (JFM), 2018
Velocity fields in horizontal plane are stitched using Taylor's approximation and decomposed into small- and large-scale fluctuations. Large-scale dynamics are highly correlated with modulations of small-scale dynamics.
