This volume collects the edited and reviewed contributions presented in the 8th iTi Conference on Turbulence, held in Bertinoro, Italy, in September 2018. In keeping with the spirit of the conference, the book was produced afterwards, so that the authors had the opportunity to incorporate comments and discussions raised during the event.
The respective contributions, which address both fundamental and applied aspects of turbulence, have been structured according to the following main topics:
I Theory
II Wall-bounded flows
III Simulations and modelling
IV Experiments
V Miscellaneous topics
Inter-scale energy transfer in a multi-scale flow.- Three-dimensional
global stability on Stuart vortex of free shear layer.- Near-wall turbulence
in a localized puff in a pipe.- Reduced description and modelling of
small-scale turbulence by means of a tensorial turbulent viscosity.-
Symmetry-Based Turbulence Modeling.- Development of a linear mode in a
turbulent boundary layer.- Spanwise organisation of buffer layer coherent
structures.- Shear/buoyancy interaction in wall bounded turbulent flows.-
Logarithmic behaviour of wall-attached structures in wall-bounded turbulent
flows.- Law of the wall and law of the wake in turbulent parallel flow.-
Large-scale energy in turbulent boundary layers: Reynolds-number and
pressure-gradient effects.- Identifying the wall signature of large-scale
motions with extended POD.- Roughness and Reynolds number effects on the flow
past a rough-to-smooth step change.- Flow dynamics in the roughness sublayer
of atmospheric boundary layers.- Convection velocities in turbulent boundary
layers over rough surfaces.- Influence of upstream perturbations on wall heat
transfer via large-scale motions.- Turbulence production in the low polymer
drag reduction regime.
