The separation of unsteadiness (or intermittency) and turbulence is the key to improving understanding of the statistical behavior of the transitional boundary layer flow. In this study an attempt is made to review the different methods used for the detection of turbulent and non-turbulent interface in transitional flows. In this regard, methods for generating the intermittency function, conditional averaging and sampling are discussed. The salient features of each technique is also explained.
