Correcting for Turbulence Effects on Average Velocity Measurements Made Using Five Hole Spherical Pitot Tube Probes.

Abstract

A procedure has been developed for correcting five hole spherical pitot tube mean velocity measurements for errors caused by velocity fluctuations associated with turbulent flow. Velocity fluctuations are independently measured with hot film or hot wire anemometers. These data are then applied to expressions derived in this report to accomplish the necessary correction. This procedure applies to the case where the pitot tube responds to average pressure differentials and is not oriented to null the cross velocity components. For the special case of isotropic flow, the results derived in this report show that corrections are not required. (Author)
