|
Considering the enhanced combustion characteristics of supersonic gas-solid two-phase enriched fuel, numerical simulation methods were employed to compare and analyze the effects of different nozzle shapes (circular, elliptical, rectangular) and nozzle arrangements (single-sided and double-sided injection, different injection angles) on the mixed combustion of enriched fuel. Research found that nozzle shape and arrangement strategy had a significant impact on combustion enhancement characteristics. Compared with rectangular nozzles, circular and elliptical nozzles could be more conducive to the combustion and heat release of enriched fuel in the combustor. In addition, increasing the number of nozzles and adjusting the nozzle angle can improve penetration depth and promote spanwise distribution, effectively expanding the contact area between enriched fuel and incoming air, thereby significantly improving the combustion rate of gas-phase components and the combustion efficiency of carbon particles. It was also found that the combustion process of particles was highly dependent on the synergistic effect of a high-temperature and oxygen-rich environment, and the excessive concentration of heat release from enriched fuel may be detrimental to the heating and ignition of particles. Therefore, creating and maintaining a stable high-temperature, oxygen-rich environment while ensuring particles to smoothly enter this ideal combustion zone is crucial for improving particle combustion efficiency and optimizing overall combustion performance.
