A procedure for predicting internal and external noise fields of blowdown wind tunnels
, 1972 The noise generated during the operation of large blowdown wind tunnels is considered. Noise calculation procedures are given to predict the test-section overall and spectrum level noise caused by both the tunnel burner and turbulent boundary layer ...
