摘要
针对国内石油化工装置大型化设计过程中空气冷却器管束内被冷却介质分布不均匀,夏季冷却效果差的实际情况,采用计算流体动力学(CFD)多相流SST模型体系对不同空冷管箱进口方案的介质流动及分布规律进行了多工况数据模拟和优化分析,结果表明,空冷器管箱入口"三管嘴"设计优于"两管嘴"的设计形式。
        Using computational fluid dynamics(CFD) techniques and SST turbulence model,the comparison and optimization of tube camber inlet solutions were carried out,which was considered to improve the performance of air cooler in a large-scale petrochemical unit.For the air cooler,CFD-simulation results shows that three-inlet plan is better than that of two-inlet.
