Institution National Research Council Canada, National Aerospace Establishment, High Speed Aerodynamics Section Date 1971-05-31 Abstract Using experimental measurements of the sound pressure and phase in the near field of a choked screech jet, a method is proposed for computing the effective source positions, their strengths and phases. Two models are considered. The first assumes a distribution of point sourees along the jet axis and the second assumes ring sources along the jet boundary instead. A technique of minimization due to Powell is used and a solution is obtained wh en the sum of squares reaches a minimum. Results for a choked jet at a screech frequency of 3170 cis are presented.
