Abstract

This paper studies the effects of heat loss at walls on flame propagation and deflagration-to-detonation transition (DDT) in micro-scale channel by high-resolution simulation. Numerical results show that wall heat loss leads to appearance of oscillating flames. This oscillating flame is attributed to the competition between viscosity and heat loss effects. Moreover, the occurrence of DDT with heat loss depends non-monotonically on the channel width.
