摘　　要：简介常用气体分布器的种类及存在的缺陷,提出了一种新型环流式气体分布器,并以某空分项目的具体参数为依托,采用Fluent软件对新型环流式气体分布器在空冷系统水冷塔中的应用进行数值模拟,模拟结果表明新型环流式气体分布器具有较好的分布性能和较小的压降,适合工程应用。叙述模型的理论验证和模拟结果。Here, the types of common gas distributors and their defects are briefed, a novel recirculating type gas distributor is described, and on basis of the parameters of a given air separation project the application of the said novel recirculating type gas distributor in the water cooling tower of air cooling system is subjected to the numerical simulation with Fluent software. The simulation results show that the novel recirculating type gas distributor renders good distribution performances and rather low pressure drop and is suitable for engineering application. The theoretical verification of the model and the simulation results are detailed.
