Deriving Lifetime Maps in the Time / Frequency Domain of Coherent Structures in the Turbulent Boundary Layer Dan

The lifetimes of coherent structures are derived from data correlated over a 3 sensor array sampling streamwise sidewall pressure at high Reynolds number (> 108). The data were acquired at subsonic, transonic and supersonic speeds aboard a Tupolev Tu-144. The lifetimes are computed from a variant of the correlation length termed the lifelength… CONTINUE READING
