Abstract
A low-pressure wind tunnel has been designed and constructed at NEMOG - UFES aiming to analyze the performance of flare gas flow measurement technologies, under critical operational circumstances. Due to hydrodynamic similarity, wind tunnel results can be extended to offshore flare gaseous flow, considering Reynolds number range. This paper presents the validation of such test facility by Laser Doppler Velocimetry technique to examine the experimental velocity profile for Reynolds number up to 680,000. Analysis shows that in the chosen test section, flow is not turbulent fully developed yet. Even so, the experimental profile factor is in a good agreement to the analytical one, with maximum deviation of 0.5%.
