Fig. 34From: Noise control for high subsonic jet flows by inner wall treatmentComparison of TA acoustic source parameters: a \({\widehat{q}}_{s}^{2}/{c}^{2}\); b \({l}_{s}\); c \({\tau }_{s}\); d \({C}_{s}\). Referred to Ref. [38], the empirical parameters are set to be \({c}_{l}=0.256\), \({c}_{\tau }=0.233\), \(A=0.755\) and \(c=0.5\)Back to article page
