Turbulence Intensity Measurement Technique for Use in Icing Wind Tunnels

摘要

Current understanding of the ice accretion process is based largely on icing wind-tunnel tests. Wind-tunnel turbulence has been identified as having potentially important effects on the results of tests performed in icing tunnels. The turbulence intensity level in icing tunnels in the absence of the spray cloud had been previously measured and found to be quite high because of the lack of turbulence-reducing screens and because of the presence of the spray system in the settling chamber. However, the turbulence intensity level in the presence of
