Experimental Study of an Acoustically Excited Plane Jet at Low Reynolds Numbers

open access: yesJournal of Applied Fluid Mechanics, 2019
The dynamics of a vertical two-dimensional air jet under acoustic excitations at a low Reynolds number are investigated experimentally. The perturbation is introduced by means of a loudspeaker located in a settling chamber before the nozzle exit.

STUDIES USING WIND TUNNEL TO SIMULATE THE ATMOSPHERIC BOUNDARY LAYER AT THE ALCÂNTARA SPACE CENTER. doi:10.5028/jatm.2009.01019198

open access: yesJournal of Aerospace Technology and Management, 2011
The Alcântara Space Center (ASC) region has a peculiar topography due to the existence of a coastal cliff, which modifies the atmospheric boundary layer characteristic in a way that can affect rocket launching operations.

Study of the structure of turbulent shear flows at supersonic speeds and high Reynolds number [PDF]

open access: yes
A major effort to improve the accuracies of turbulence measurement techniques is described including the development and testing of constant temperature hot-wire anemometers which automatically compensate for frequency responses.

System for measuring Reynolds in a turbulently flowing fluid [PDF]

open access: yes, 1976
A system for measuring momentum flux in a turbulently flowing fluid includes: a sensing apparatus for dynamically sensing the mainstream and the cross velocity components of the fluid, a transducer operative to provide two electrical output signals ...

A wind model for an elevated STOL-port configuration [PDF]

open access: yes
Measurements of mean velocity magnitude and direction as well as three-dimensional turbulence intensity were made in the flow over a model of an elevated STOL-port. A 1:300 scale model was placed in a wind tunnel flow simulating the mean velocity profile

An experimental study of a self-confined flow with ring-vorticity distribution [PDF]

open access: yes
A new form of self-confined flow was investigated in which a recirculation zone forms away from any solid boundary. An inviscid flow analysis indicated that in a purely meridional axisymmetric flow a stationary, spherical, self-confined region should ...

Experimental measurements of unsteady turbulent boundary layers near separation [PDF]

open access: yes
Investigations conducted to document the behavior of turbulent boundary layers on flat surfaces that separate due to adverse pressure gradients are reported.
