CFD Simulation and Experimental Validation of Fluid Flow in Pre-distributor

液体分发者是一很为蒸馏列内部的进口。分发者前通常为起始的分发被放在分发者的顶上。在分发者前的液体流动是有许多孔和支店的可变集体流动的一个复杂系统。因而，分发者前当模特儿的二个阶段被执行，与免费表面模型一起的同类的模型被使用。数字方法被与试验性的数据作比较验证。用在流出之上的不同分发者前，流入率的影响，地点和取向的模仿的结果，分发被调查。而且，流出分发影响因为在马槽的液体一致性上的分发者前也被分析。结论能为液体分发者的结构的设计和大规模的分发者前被采用。

Liquid distributor is a very import intemal for distillation columns. Pre-distributor is usually set on the top of distributor for initial distribution. Fluid flow in pre-distributor is a complex system of variable mass flow with many orifices and sub-branches. Consequently, the two phase modeling of pre-distributors was carried out andthe homogeneous model with free surface model was applied. The numerical method was validated by comparing with experimental data. Using the simulated results for different pre-distributors, the impacts of inflow rate, location and orientation uoon the outflow distribution were investigated. Furthermore, influences of the outflow distribution for pre-distributor on liquid uniformity in trough were also analyzed, The conclusions can De aaoptea for me structural design of liquid distributor and pre-distributor of large scale.
