✦ Synopsis

The propagation of premixed flames centrally ignited at one of the end flanges of a closed cylindrical vessel and the flame-induced fluid flow have been investigated in the present study. Photographic records show that under specific geometrical conditions the flame exhibits a cone form with a backward directed top, called "tulip"-shaped. This appears after the flame has lost a main part of its area by side wall quenching. With a laser-Doppler anemometer the instantaneous flow velocity during the short explosion process was measured together with pressure records. An analogy to the experiments of Markstein (see Markstein, G. H. (Ed.), Nonsteady Flame Propagation) is shown and the explanations of several authors for the "tulip" formation are given.
