In order to study the best matching relation of bluff-body structural parameters in advanced vortex combustor (AVC), numerical simulation on the cold state flow in combustor was carried out. The results indicate that the combustor has better flow characteristics by the layout of bluff-body presented in model I, when the equivalent ratios of structural parameters are H₁/H2 =0.7 and S/H₁ = 0.6, total pressure loss coefficient is lower and stability of vortex is stronger. The selection rule of structural parameters in AVC can not copy totally from the stability of vortex formation structure relation in Trapped Vortex Combustor (TVC) .
Key words: ramjet; vortex combustor; structural parameters; turbulence; total pressure loss
