  1. International Scientific SeminarFrontiers of numerical jet modelling: from engineering to environmental flows The Kavli Royal Society International Centre, 10-12 January 2011 Organised by Sergey Karabasov, University of Cambridge

  2. Motivation for the meeting Jets are one of the most fascinating topics in fluid mechanics. They occur in a number of engineering and environmental flows, from high-speed aero engines to the streams of cooling air applied inside a gas turbine, and from the smoke of a chimney pipe to the mesoscale currents in ocean circulations. In case of high-Reynolds number flows, the jet development involves a great diversity of length and time scales. Because of a poor understanding of turbulence phenomena, especially for transitional flows, jet modelling is very challenging. This seminar is proposed as a discussion forum for the experts who develop and apply novel techniques in three different research areas – aeroacoustics, turbomachinery and environmental flows. The goal is to initiate discussions between those who develop new mathematical modelling techniques, those who need accurate tools for understanding the new physical mechanisms in formation and development of jet flows, and those, who are involved in both research activities.
