Turbulent jet noise is a controversial fluid mechanical puzzle that has amused and
bewildered researchers for more than half a century. Whereas numerical simulations are …

A critical review of both experimental and computational studies of round turbulent jets is
provided, beginning with the work of Tollmien (1926). This review traces the history, the …

Turbulence pervades our world, from weather patterns to the air entering our lungs. This
book describes methods that reveal its structures and dynamics. Building on the existence of …

A tool to analyse correlated events in turbulent flows based on an extended proper
orthogonal decomposition (POD) is proposed in this paper. A general definition of extended …

For fluid flow one has a well-accepted mathematical model: the Navier-Stokes equations.
Why, then, is the problem of turbulence so intractable? One major difficulty is that the …

Results are presented from pressure measurements performed in the irrotational near field
of unbounded co-axial jets. Measurements were made for a variety of velocity and …

▪ Abstract We discuss a few applications of active control of turbulent fluid flow and their
implications for the economy and the environment. We outline a conceptual basis for control …

Townsend's attached eddy hypothesis assumes the existence of a set of energetic and
geometrically self-similar eddies in the logarithmic layer in wall-bounded turbulent flows …

Experiments were carried out in an axisymmetric turbulent jet from 2 to 6 diameters
downstream at exit Reynolds numbers of 78 400, 117 600, and 156 800. Data were …

This investigation compared the application and accuracy of single-and multi-time-delay
linear stochastic estimation-proper orthogonal decomposition (LSE-POD) methods in the …
