Modifications of the Penn State Boundary Layer Research Facility for Boundary Layer/Structure Interaction Experimental Research.

摘要

Modifications to the Penn State Boundary Layer Research Facility (BLRF) have been made so that low wavenumber turbulent boundary layer (TBL) wall pressure fluctuation spectra can be measured. In addition, fundamental experimental research on boundary layer/structure interaction can be conducted. Modifications include the design and fabrication of a new test section to accommodate a long flat elastic test plate in contact with the boundary layer and extensive treatments to reduce background vibration levels in the test plate. The design, fabrication and installation of these modifications are described. (SDW)
