Summary

First considerations of setting up a mathematical model for coherent structures in turbulent boundary layers without pressure gradient are presented. Using the method of W Albring the vortex transport equation is solved step by step. Starting points of the considerations are the definition of coherent structures according to F. Hussian and experimental discoveries.
