Introduction

Separated flows and jets, being the subjects of individual

branches of aerodynamics, are closely linked in a variety of

applications. They are of paramount importance in various fields

of fluid mechanics including vehicles efficiency, technical

branches bound up with gas/liquid flows, atmospheric effect on

various constructions, etc. The future progress in these fields

is associated, in a large measure, with the extend of knowledge

of the physics of separated flows and jets, achievements in the

oretical approaches and calculations as well as development of

perfect control techniques.

These aspects were in focus of IUTAM-Symposium which was

held in Novosibirsk, 1990. About 120 presentations and well

guided general discussions which took place indicated wide in

terest to the themes of the Meeting. The volume is composed of

the contributions arranged according to their place in the

scientific programme of the Symposium. Thus, the following

main sections may be distinguished, conditionally to some ex

tent: numerical simulations and theoretical approaches - general

aspects, incompressible turbulent boundary layer separation,

shock waves/turbulent boundary layer interactions, control techniques, laminar separation and instability, organized structures

in jets, separated flows and mixing layers. Surely, inspite of great number of contributions the material do not exhaust all

the problems associated with separated and jet flows, but gives

insight into the main research fields. An interested reader will

find here the state of the art, the leading trends and will be

given a chance to avaluate the progress achieved since the pre

vious IUTAM-Symposium on Boundary Layer Separation, London,19B6.
