This volumecollects various contributions from the 5th International Conferenceon Jets, Wakes and Separated Flows (ICJWSF2015) that took place in Stockholmduring June 2015. Researchers from allaround the world presented their latest results concerning fundamental andapplied aspects of fluid dynamics. With its general character, the conferenceembraced many aspectsof fluid dynamics, such as shear flows, multiphase flows and vortex flows,for instance. The structure of the present book reflects the variety of topicstreated within the conference i.e. Jets, Wakes, Separated flows, Vehicleaerodynamics, Wall-bounded and confined flows, Noise, Turbomachinery flows,Multiphase and reacting flows, Vortex dynamics, Energy-related flows and asection dedicated to Numerical analyses.
