The Influence of Bluff-Body Structural Parameters and Incoming Velocities on Advanced Vortex Combustor

Abstract:

The influence of bluff-body structural parameters and incoming velocity on the cold flow field of advanced vortex combustor (AVC) has been studied, and the results show that the vortex in cavity can be the most stable and the total pressure loss can be the least when structural parameter is B2/B1=0.7, L/B1=0.8. The incoming velocity should not be too high or too low, it should be combined with specific structural parameters of the combustor, the combustion flame speed, fuel type, and the stoichiometric ratio and other factors. If AVC design is reasonable, the cavity can not only stabilize the flame, but also not be sensitive to the speed changes.
