Abstract A method is introduced of educing coherent eddy structures from turbulent flows and quantifying the variation of the structures found. The method has been applied to conditionally sampled flow fields associated with ejection events in a numerical simulation of a turbulent boundary layer at very low Reynolds number. It is found that asymmetric streamwise vortical structures, reminiscent of those seen in smoke visualizations, are consistently associated with the ejection events. The size of these organized eddies is related loosely to the position of the ejection.
