Development and Compatibility of Flow Seeding Techniques for LV Measurements in a Diversity of Research Test Flows
Abstract
Particle seeding techniques and generations have been developed to provide scattering centers for laser velocimeter data acquisition in a diversity of research test flows at the Aeromechanics Division of the Air Force Wright Aeronautical Laboratories. The facility flows range from the subsonic through hypersonic regimes, including aerothermal flow and a water tunnel. The compatibility and environmental problems with introducing seeding material into tunnel flows are discussed. Exploratory findings of natural particulate matters are presented. An in-house developed high pressure particle generator is described. Applications of a number of generating techniques to these tunnels include dispersion and data rate information in the test sections. Particle sizing measurements are presented with a variety of fluids, fluid viscosities, and generators.
