Prospective Noise Reduction by Domes on Planar Arrays. I. Theoretical Estimates for Unilayers
CONTROL DATA CORP MELVILLE NY TRG DIV
Pagination or Media Count:
The reduction of direct turbulent boundary-layer noise in a planar array by a fluid unilayer interposed between the array and the flow is assessed from theoretical considerations. The layer is composed of independent contiguous segments each of superficial dimensions large relative to the sound wave length in the interior.
