Progress in Turbulence VIII: Proceedings of the iTi Conference in Turbulence 2018 (Springer Proceedings in Physics Book 226)

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.
