Study on vapor-liquid flow states of hanging downcomer bottom-orifices;
悬挂式降液管液流孔气液流动状态研究
The vapor-rise-up of the hanging downcomer with 8 or 12 bottom-orifices was investigated in a transparent plexiglass column(diameter 500 mm) with air-water system,and the model of vapor-rise-up was built up supposing that the pressure drop generated by rise-up vapor through the downcomer equaled to the tray pressure drop.
采用空气-水物系,在直径为500 mm的有机玻璃塔中对底部分别开有8个和12个液流孔的悬挂式降液管的漏气进行了研究,并在假设漏入降液管的气体产生的压降与板压降相等的基础上建立了击穿漏气模型。
