本文对于直-弯管内的气固两相流动进行了分析,确立了直、弯管内两相流动的相似准则数;得出了稳定状态下直、弯管内颗粒浓度的分布,以及直管内两相中的颗粒开始发生沉积的临界浓度的关系式.
In this paper, the gas-solid two-phase flow in a straight-elbow pipe is analyzed, and the similarity criterion of two-phase flow in straight pipe and elbow pipe is established. The distribution of particle concentration in straight pipe and elbow pipe under steady state is obtained, The relationship between the critical concentration at which deposition of the particles in the two phases in the tube begins to occur.
