Congratulations to Dominic for the publication of his paper Correlation Analysis of High-Resolution Particle Image Velocimetry Data of Screeching Jets in the American Institute of Aeronautics and Astronautics Journal. This is the first of a two-part paper (the original paper we submitted was so long the journal asked us to split it in two), summarizing the work that Dominic has performed with Prof. Sergey Karabasov and his group at QUML. This paper focuses on analysis of velocimetry data of supersonic jets, to extract length and timescales relevant to the theoretical models for broadband shock-associated noise that Prof. Karabasov’s group has developed.
