摘要:
为厘清压缩空气泡沫在高层建筑垂直管网的输运特性，选取压缩空气A类泡沫作为研究对象，通过数值模拟方法研究气液比、管径和供液流量对压缩空气A类泡沫垂直管网输运压力衰减的影响规律。研究结果表明：在气液比为6~10范围内，压缩空气泡沫在管径为80，100，125，150 mm垂直管道输运过程中，总压降随气液比增大而减小，管径为65 mm时，气液比对压力衰减影响是非单调的；相同供液流量和气液比条件下，总压降随着管径增大而减小，当供液流量增加时，管径对总压降影响更明显；相同管径和气液比条件下，总压降与供液流量正相关，且对于管径较小的65 mm管道而言，供液流量对总压降影响更明显。研究结果对于压缩空气泡沫系统在高层建筑应用中的管网设计具有重要理论指导意义。
Abstract:
In order to clarify the transport characteristics of compressed air foam in the vertical pipe network of high-rise buildings,compressed air class A foam is selected as the research object,and the influence of gas-liquid ratio,pipe diameter and liquid supply flow rate on the pressure attenuation of compressed air class A foam transport in vertical pipe network is studied by numerical simulation.The results show that the total pressure drop decreases with the increase of gas-liquid ratio in the range of 6~10,and the effect of gas-liquid ratio on pressure attenuation is non-monotonic when the pipe diameter is 65 mm; Under the same flow rate and gas-liquid ratio,the total pressure drop decreases with the increase of pipe diameter,and the effect of pipe diameter on the total pressure drop is more obvious when the supply flow rate increases.Under the same pipe diameter and gas-liquid ratio,the total pressure drop is positively correlated with the liquid supply flow rate,and for the pipe diameter less than 65mm,the liquid supply flow rate has a more significant effect.The research results have important theoretical guidance for the design of pipeline network of compressed air foam system in high-rise building applications.
