摘要
A two-dimensional spray combustion code is developed for investigating the spray flame in a gas turbine combustor. The modified K-epsilon model is used to describe the turbulent flow field and the generalized Rosin-Rammler equation is used to evaluate the fuel droplet size distribution in the spray. The effects of the inlet turbulent kinetic energy K0 and dissipation rate epsilon0 on the flow velocity and the length of recirculation zone are studied. Compared with results in the isothermal flow, the recirculation strength will increase, but the length of the recirculation zone will decrease in reacting flow case. Also, the influence of bluff-body size on velocity, temperature, fuel/oxygen concentration, and droplet distribution profiles is studied in detail.
