Abstract: In order to provide a reference of the actual spray evaporation and combustion,Threedimensional swirling spray combustion under different condition were studied by Direct Numerical Simulation(DNS).The gas combustion was modeled by an adaptive one-step reaction mechanism,the droplets were tracked in Lagrangian framework and the evaporation was described by infinite heat conduction model.We have learned the time-average character for both gas phase and liquid phase.It was found that there is mutually reinforcing effect between the combustion and the central recirculation zone(CRZ).Co-swirling leads to a stronger central recirculation zone(CRZ),but there will be a smaller outer recirculation zone(ORZ).The reaction rate is much higher and evaporative cooling effect is more obvious in rich combustion.Turbulence inflow will make contribution to higher dispersed droplets and smaller droplets.
