A measurement system for turbulence properties in a three- dimensional flow using a data logger
An analysis is presented for hot wire/film anemometer measurement of mean velocities and turbulent stresses in a three dimensional flow field with a predominant flow direction. The experimental data can be taken with an automated traverse under the control of a digital data acquisition system which …

An experimental study of solid particle motion in a turbulent liquid pipe flow
… plexiglas tube. One goal was to measure the turbulence properties of the particles in the r-$\theta$ plane with a previously developed axial viewing photographic technique. Another goal was to determine the effects of the inherent inhomogeneities of turbulent pipe flow on the results.

Experimental and numerical investigations of the off-design flow physics in a supersonic through-flow fan cascade
… of profiles of both the mean and turbulent wake properties were found to be strongly influenced. by upstream shock-boundary-layer-interactions, the strength of which varied with cascade incidence. In contrast, the peak levels of turbulence properties within the shear layer were found to be …

Free surface dynamics in shallow turbulent flows.
… flows. Experimental data has shown that the turbulence properties at a point near the free surface relate directly to the properties of the free surface pattern. This would suggest a direct linkage between the free surface and the underlying turbulence field, but this cannot be true since the …

Investigating the Interaction of a Supersonic Single Expansion Ramp Nozzle and Sonic Wall Jet
… investigation into the flow field and turbulence quantities of a modern jet nozzle configuration.</p> <p>A rectangular supersonic multi-stream nozzle with aft deck is characterized using time-resolved schlieren imaging, stereo PIV measurements, deck mounted pressure transducers, and …

Measurement of simultaneous fluctuating loads at multiple levels on a model of a tall building in a simulated urban boundary layer
… of sp:i,res and floor roughness elements. Flow properties were measured in detail at the model location, seven meters downstream of the spires. Properties measured included the mean velocity and turbulence characteristics for all three velocity components. Turbulence properties included …

An Experimental Investigation of Underbody and Near Wake Aerodynamics of Heavy Goods Vehicles
… Their unsteadiness may be assessed by evaluating turbulence properties. Whilst Reynolds stresses are generally found to be low, locally there are regions with low time-averaged velocities where the turbulent activity can be quite dominant, primarily in the wake. Instantaneously, no evidence of …

Caracterización numérica de la turbulencia en el estela de una aeroturbina mediante un modelo de simulación de grandes escalas
… of study. Velocity defects and the increase of turbulence generated by the turbines in a wind farm usually cause a reduction in power generation and unsteady loads over other machines. In wind farms where, because of shortage of space, high cost of civil works, etc., the wind turbines are placed …
