Abstract

The influence of different structural parameters of a three-duct trapped vortex combustor(TVC) with flow guide vanes on flow fields, combustion efficiency and total pressure loss coefficient are numerically studied. The results show that the ideal dual vortices can be formed in the cavity, which enhance the stability of flame and the mixing of gas, combustion efficiency. The structure parameter a/E influences the performance of the TVC significantly, while the changes of b/H and c/L have little effect on the combustion efficiency, but c/L has some effects on the total pressure loss coefficient. When a/E=0.5, b/H=0.5, c/L=0.5, the best performance of the TVC is achieved with the combustion efficiency 99.669 8%, the total pressure loss coefficient 3.126 8%.

Key words： trapped vortex combustor; flow guide vanes; combustion efficiency; total pressure loss coefficient; numerical simulation
