Spherically expanding flame simulations in Cantera using a Lagrangian formulation [PDF]

, 2021
A Lagrangian-based one-dimensional approach has been developed using Cantera to study the dynamics of spherically expanding flames. The detailed reaction model USC-Mech II has been employed to examine flame propagating in hydrogen-air mixtures. In the first part, our approach has been validated against laminar flame speed and Markstein number data from

Flame surface statistics of constant-pressure turbulent expanding premixed flames [PDF]

, 2014
In this paper we investigate the local flame surface statistics of constant-pressure turbulent expanding flames. First the statistics of local length ratio is experimentally determined from high-speed planar Mie scattering images of spherically expanding
