Acoustical experiment of low noise wall models for testing section in transonic wind tunnels
摘要
Abstract
Acoustical Experiment of Low noise Wall models for testingsection in transonic Wind tunnels is introduced in this paper. The Experimental results are provided to show that: (1) edgetone generated by slanted hole configuration is main sound source, (2) Screen and spllitter-plates successfully suppress the edgetone, (3) The design way in refer ence[1] for low noise wall is very useful.关键词
