Bidimensional simulation of premixed turbulent flame characteristics in an adiabatic vessel using Monte Carlo method

Abstract

The main objective of this work is to simulate premixed turbulent flame in an adiabatic closed vessel using Monte Carlo scalar PDF transport method in two-dimensional geometry. We try principally to define turbulent flame characteristics during flame front propagation as: flame mean radius, flame turbulent radius, flame-wrinkling rate, flame-brush thickness and turbulent flame velocity. It is worth noting that the flame Kernel in the two-dimensional configuration grows having a wrinkled circular shape. Furthermore, the flame mean radius and the flame turbulent radius enhance more rapidly when increasing turbulence intensity or equivalence ratio.
