Performance analysis on trapped vortex combustor with barchan dune bluff body
In order to study the effect of barchan dune bluff body on the performance of the trapped vortex combustor(TVC),windward slope angle α,leeward slope angle β,and the distance L between the highest point(dune top)on the windward slope and the inlet surface were analyzed by numerical simulation,and the influences on the total pressure loss,combustion efficiency and the outlet temperature change were obtained.Results show that the dune bluff body can effectively improve combustion properties,and the increase of the angle of α,β and the distance L can improve combustion efficiency and homogeneity of the exit temperature distribution.When α=20°,β=40° and L=45 mm,comprehensive combustion effect is the best.
