Sinusoidal Excitation of a Free Turbulent Jet With Constant Amplitude Transverse Pressure Gradients Near the Nozzle Exit: Part I: Measurement of Mean Shear Velocities

Journal of Dynamic Systems, Measurement, and Control, 1973
A free turbulent jet is perturbed transverse to the flow direction by a sinusoidal pressure gradient near the nozzle exit. Velocities in the jet are determined by hot wire anemometer measurements. Moving effective mean velocity profiles are defined and reconstructed from the point-by-point stationary measurements of the mean velocity and of the ...

Effects of blanket, drains, and cutoff wall on reducing uplift pressure, seepage, and exit gradient under hydraulic structures

2015
Upstream blankets, drains and cutoff walls are considered as effective measures to reduce seepage, uplift pressure and exit gradient under the foundation of hydraulic structures. To investigate the effectiveness of these measures, individually or in accordance with others, a large number of experiments were carried out on a laboratory model.

Sinusoidal Excitation of a Free Turbulent Jet With Constant Amplitude Transverse Pressure Gradients Near the Nozzle Exit: Part II: An A-C Fluidic Model for the Jet Gain

Journal of Dynamic Systems, Measurement, and Control, 1973
A free turbulent jet is perturbed transverse to the flow direction by a sinusoidal pressure gradient near the nozzle exit. An a-c model for the jet gain, based upon the control region dynamics and a uniform deflection of the jet downstream of this region, is generally verified in conjunction with attenuated mean shear velocities.

Performance of gas saturators in the presence of exit stream temperature gradients and implications for chemical vapor deposition saturator design

Chemical Engineering Science, 1994
When a carrier gas is passed through a gas saturator at temperature T0 containing liquid or solid reagent under conditions leading to its saturation with an equilibrium vapor pressure p∘ of the reagent, and then into a tube where the exit stream temperature is increased to T∞, the downstream partial pressure of reagent, p∞, may be less than p∘ due to ...
