Research output: Contribution to journalArticlepeer-review


The paper presents numerical simulations of three-dimensional Bunsen burner polyhedral premixed flames within the framework of a weakly nonlinear semi-phenomenological model for flame interface dynamics. In addition, for slot-burners, experimental observations were made and measurements were obtained of the limit velocity for transition from polyhedral to smooth flame. In a qualitative agreement with the experimental observations, the numerical results show that the occurrence of the polyhedrals is largly controlled by the conditions at the burner rim.
