Abstract
Effect of cavity on combustion efficiency and blow off characteristic of fuel injection/stabilization integrated strut flame stabilizer were experimentally investigated under the condition of incoming flow temperature 780-850℃, incoming flow Mach number 0.16, fuel air ratio 0.002-0.006. Numerical simulation was also used to assist analysis. The results show that integrated strut flame stabilizer with cavity could achieve stable and high efficiency flames under the condition of various fuel air ratios; combustion efficiency of integrated strut flame stabilizer without cavity is worse than that of the integrated strut flame stabilizer with cavity, the differences between the integrated strut flame stabilizer with cavity and without cavity decreases gradually with the increase of fuel air ratio; the flame stabilizer with cavity performs better on blow off than flame stabilizer without cavity. Cavity structure could promote the atomization and evaporation characteristic of fuel, and improve combustion characteristics of integrated strut flame stabilizer.
