Turbulent flow is a most important branch of fluid dynamics yet its
complexity has tended to make it one of the least understood. Empirical
data have been appearing rapidly for more than twenty years but a
consistent theory of turbulent flow based on the results has been
lacking. The original edition of Dr Townsend's book was the first to
attempt a systematic and comprehensive discussion of all kinds of
turbulent motion and to provide a reliable analysis of the processes
which occur. The theory and associated concepts are applied to the
description of a variety of flows: free turbulent flows such as wakes
and jets, wall flows in pipes and boundary layers, flows affected by
buoyancy forces such as heat plumes and the atmospheric boundary layer
and flows with curved streamlines. This monograph will appeal to
practitioners and researchers in engineering, meteorology, oceanography,
physics and applied mathematics. This paperback edition was first issued
in hard covers in 1976 as a complete revision, taking into account
developments since 1955, of the first edition. It will be useful as an
advanced text in applied mathematics, and the other disciplines
mentioned above.
