Numerical analysis of tulip flame by dynamic mode decomposition
Ratan Joarder
Abstract:Inversion of a premixed flame front to the shape of a tulip flower during the last stage of its propagation in a channel or tube of aspect ratio greater than two has intrigued the scientific community for decades. In the present work, the tulip inversion of hydrogen-air premixed flame is simulated numerically in two dimensional domains of aspect ratio 7.32, and 3.66. Dynamic Mode Decomposition (DMD) is carried out on the two-dimensional pressure distribution obtained from the numerical simulation to understand… Show more
