本文采用全双流体模型对部分切向进气管式双侧进气突扩燃烧室内的液雾燃烧过程进行了数值模拟，将液雾群按初始尺寸分组，数值模拟结果表明不同尺寸液雾的蒸发及燃烧过程显著不同，小尺寸的液雾是先蒸发后燃烧，而较大尺寸的液雾则是边蒸发边燃烧．模拟结果还表明，部分切向进气方式有利于在燃烧室的头部产生大面积的中心回流区，该回流区的存在有利于加强混合及火焰稳定．
In this paper, a full two-fluid model is used to simulate the liquid mist combustion process in a partially tangential inlet ducted combustion chamber. The liquid mist groups are grouped according to their initial size. The numerical results show that the liquid mist with different sizes Evaporation and combustion processes are significantly different, small size of the liquid mist is first evaporated after the combustion, while the larger size of the liquid mist while the side of the combustion edge evaporation. The simulation results also show that the partial tangential intake mode is advantageous for generating a large area of central recirculation zone at the head of the combustion chamber, which is advantageous for enhancing mixing and flame stabilization.
