本文用二维激光多普勒测速仪和探针取样法对大速差射流燃烧室中冷态三维湍流气固两相流动进行了实验研究,测量了气相速度,颗粒速度、颗粒质量流分布及两相各自的湍流特性,探讨了高速射流作用下两相流场的主要物理特征及其对火焰的稳定和强化燃烧的作用。
In this paper, the two-dimensional laser Doppler velocimeter and probe sampling method were used to study the gas-solid two-phase flow in the cold state of large velocity difference jet combustor. The gas velocity, particle velocity, particle mass flow distribution and The two turbulent characteristics of two phases are discussed. The main physical characteristics of the two-phase flow field under high-velocity jet and their effects on the stability and enhanced combustion of the flame are discussed.
