Hot wire anemometer measurements in the unheated air flow tests of the SRB nozzle-to-case joint [PDF]

open access: yes
Hot-Wire Anemometer measurements made in the Solid Rocket Booster (SRB) nozzle-to-case joint are discussed. The study was undertaken to glean additional information on the circumferential flow induced in the SRB nozzle joint and the effect of this flow ...

Development of subminiature multi-sensor hot-wire probes [PDF]

open access: yes, 1988
Limitations on the spatial resolution of multisensor hot wire probes have precluded accurate measurements of Reynolds stresses very near solid surfaces in wind tunnels and in many practical aerodynamic flows.

Local isotropy and refractive index fluctuations in the surface layer of the atmosphere [PDF]

open access: yes
Theoretical and experimental evidence for the existence of local isotropy is briefly examined and conflicting results are found. Recent measurements of temperature spectra support earlier hot wire anemometer and optical scintillation measurements that ...

Studies using wind tunnel to simulate the Atmospheric Boundary Layer at the Alcântara Space Center [PDF]

open access: yesJournal of Aerospace Technology and Management, 2009
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.

Laryngeal Nerve Activity During Pulse Emission in the CF-FM Bat, Rhinolophus ferrumequinum. II. The Recurrent Laryngeal Nerve [PDF]

open access: yes, 1981
The activity of the recurrent laryngeal nerve (RLN) was recorded in the greater horseshoe bat,Rhinolophus ferrumequinum. Respiration, vocalization and nerve discharges were monitored while vocalizations were elicted by stimulation of the central gray ...
