This work presents the statistics of flame-self interaction during boundary layer flashback of a hydrogen-rich premixed flame. It is shown that the flame topology is significantly affected by the turbulent boundary layer and the heat loss to the wall. Furthermore, it is shown that the choice of the species used to define the progress variable has a significant influence on the distribution of flame-self interaction topologies.
