To continue our (Saddoughi & Veeravalli 1994) tests of the local-isotropy predictions of Kolmogorov's (1941) universal equilibrium theory in shear flows, we have taken hot-wire measurements of the velocity fluctuations in complex turbulent boundary l

Turbomachines are used in a wide range of applications. Increasing the efficiency and operating range of turbomachines reduces fuel consumption of gas turbine power plants and other applications. Over the years, many attempts have been made to achiev

It is shown that most of the present-day hot-wire anemometers have a limitation at high frequencies: namely that the tail of the power spectrum of the anemometer output signal has a spurious rise with frequency. This rise, which is proportional to th

In this paper the fractal nature of velocity signals as measured in turbulent flows is investigated. In particular, we study the geometrical nature of the graph (x,f(x)) of the function f that gives one component of the velocity at position x. Specia

To test the local-isotropy predictions of Kolmogorov's universal equilibrium theory, we have taken hot-wire measurements of the velocity fluctuations in the test-section-ceiling boundary layer of the 80×120 foot Full-Scale Aerodynamics Facility at N

The range of validity of Kolmogorov's [1] local-isotropy hypothesis in complex flows is investigated. We show that for high-Reynolds-number boundary layers under the influence of large extra mean strain rates, the lower-wavenumber limits of locally-i

Detailed measurements of the velocity field were made in the wall boundary layer of the 80’ by 120’ facility at NASA Ames. The Reynolds Number Rλ, based on the Taylor microscale λ at the measurement location, was approximately 1450, one the lar

The effect of prolonged streamline divergence on developing turbulent boundary layers is investigated using an experimental approximation of the source flow over a flat plate to achieve a simple divergence. Results are presented of hot-wire measureme
