:采用三维相位多普勒颗粒分析仪(PDA)对旋流浓淡燃烧器出口区域两相流动特性进行了实验研究,获得了该燃烧器在不同旋流叶片开度、旋流二次风和直流二次风配比下的气固两相流场和浓度场的分布规律,并且对这些分布规律进行了分析。
A three-dimensional phase-Doppler particle analyzer (PDA) was used to study the two-phase flow in the outlet region of the swirler-rich burner. The characteristics of the burner at different swirl vane opening, swirling secondary air flow and direct current The distribution law of the gas-solid two-phase flow field and the concentration field under the secondary air mixing ratio, and analyzes the distribution rules.
