Turbulent patches and their streamwise evolution play a major rôle in the late stage of any transition scenario. The appearance of turbulent patches in laminar boundary layers was first noted by Emmons [1], who proposed a turbulent spot probability appearance model, which recently [2] has proven to work well for the free stream turbulence (FST) induced transition scenario. However, there are many fundamental questions still remaining unanswered, which are important in the striving after new transition prediction models.
