Numerical simulation of effect of acetone droplets injection on methane/air laminar premixed flame behavior

Abstract

As an attempt to investigate the effect of acetone droplets on methane/air laminar premixed flame behavior such as laminar flame speed, Markstein length, and flame structure, two-dimensional direct numerical simulations (DNS) are performed under different conditions of equivalence ratio and phase of acetone. The result suggests that the evaporation of acetone droplets increases flame instability and inhibits the increment of laminar flame speed.
