Investigation on effect of mixing distance on mixing process and combustion characteristics of double-cone burner

Investigations of mixing process, combustion and emission characteristics have been performed in a double-cone premixed burner under various mixing distances. The complex flow field and flame structure are accurately captured by the simulation model. The modified unmixedness coefficient, flame index, NO, CO emissions have been calculated and analyzed in detail. Numerical results show that the dimensionless mixing distance has a significant...
