摘要：

The analysis on two-phase flow in a Lean Direct Injection(LDI) combustor has been investigat ed. Linearized Instability Sheet Atomization(LISA) and Aerodynamically Progressed Taylor Analogy Breakup(APTAB) breakup models are applied to simulate the droplet breakup process in h ollow-cone spray. Breakup model is validated by comparing penetration length and Sauter Mea n Diameter(SMD) of the experiment and simulation. In the LDI combustor, Precessing Vortex C ore(PVC) is developed by swirling flow and most droplets are atomized along the PVC. It has been confirmed that all droplets have Stokes number less than 1.0.
