Gemini South Wind Test Data and Analysis

GEMINI SOUTH WIND TEST DATA CODE ID = t04530cc

Average and RMS wind pressures and average wind velocities were calculated from the wind test in the following conditions:

Wind attack direction to SLIT = 045 degree Azimuth angle
Zenith angle = 30 degree (60 degree Elevation)
Upwind gate : closed
Downwind gate: closed

At +X: Resultant .8 m/s
U= -.3 V= -.4 W= -.1
Resultant V_RMS = .3

At -X: Resultant 2.4 m/s
U= 1.6 V= -1.4 W= 1.1
Resultant V_RMS = .1

At -Y: Resultant .5 m/s
U= -.2 V= .0 W= .1
Resultant V_RMS = .2

At M2: Resultant .7 m/s
U= .1 V= -.3 W= .2
Resultant V_RMS = .3

At Dome: Resultant 3.7 m/s
U= .4 V= -.5 W= 1.3
Resultant V_RMS = 2.5
