摘要：

The present article treats with numerical simulation of vortical structures in the combustion field in a two-dimensional bluff-body burner. The numerical results support the flow visualization results for C3H8 combustion by Chin & Tankin. We identify the fuel effect on the dynamic vortical structures inside the flame for C3H8 and CH4 fuels. The thermal buoyancy is found not to be responsible for the flow instability inside the flame in the presence of a large co-flowing air stream although there exists thermally induced vortex outside the flame.
