| 초록 |
Three-dimensional numerical analysis of the turbulent premixed flame propagation in a constant volume combustion chamber was performed by the flame surface density(FSD) model. A transport equation for FSD was derived from the transprt equation for the turbulent dissipation rate of fuel concentration using the assumption of proportionality between the dissipation rate and FSD. To consider the effect of flame quenching near the wall, the regions of reacting flow in the combustion chamber were classified into three zones, i.e. viscous, buffer, and turbulent zones, where the different production and destruction rates for FSD were applied. |
