Autoignition-affected stabilization of laminar nonpremixed DME/air coflow flames

The structure and stabilization mechanism of laminar nonpremixed autoignitive DME/air coflow flames were investigated. Computations were performed at 30 atmospheres with uniform inlet velocities of 3.2 m/s for both streams, and the coflow air boundary temperatures were 700, 800, 900, and 1100 K. The heat release rate and species profiles were examined for each case. Further investigation with Chemical Explosive Mode Analysis (CEMA) and...
