Turbulent Shear Flows 7 : Selected Papers From the Seventh International Symposium on Turbulent Shear Flows, Stanford University, USA, August 21–23, 1989

The Seventh Symposium was held on the campus of Stanford University with·a combination offacilities and weather which made it possible to add open-air poster sessions and coffee breaks to the programme. This was particularly convenient as the call for papers attracted close to three hundred abstracts and a total number of participants well in excess of this number. Some one hundred and thirty papers were presented in carefully phased parallel sessions and thirty six further contributions were made available in the form of posters. In addition, a lively open-forum session allowed additional speakers to make brief presentations. The staff of the Thermo-Sciences Division of the Department of Mechanical Engineering at Stanford undertook the local arrangements with evident success and their extensive record of contributions to Turbulent Shear Flows made the venue particularly appropriate. Also, the Centre for Turbulence Studies, based on the faculty of the University and the NASA Ames Research Center, provided a considerable body of expertise with emphasis on direct numerical stimulation.

A carefully refereed selection of papers of lasting value gives an overview of the present status of turbulent shear flow research, including both theoretical and experimental work. The section on reacting flows emphasizes research on combustion problems. The book is an important reference for researchers and engineers.
