摘要

为了研究洗涤冷却环内冷却水流动的情况，借助计算流体力学软件Fluent建立了洗涤冷却环流体冷态流动的数学模型，同时为了验证模型的可靠性，对洗涤冷却环出口处的流动情况进行了实验研究，实验结果与模拟结果基本吻合。结果表明：因为洗涤冷却环的结构限制，其内部存在多处涡旋区域；内室入水口周向位置处的涡旋运动最为剧烈；受其影响，入水口周向位置的射流孔出口平均速度最小，两入水口之间周向位置的射流孔出口平均流速最大；槽缝出口的平均流速在周向上的分布与射流孔出口平均流速分布相同。

Abstract

In order to investigate the flow behavior of cooling water in scrubbing-cooling ring

especially at the outlet of the ring

a mathematical model for the fluid flow in scrubbing-cooling ring was established with Fluent

a software of computational fluid dynamics. The experimental study was carried out to measure the average velocity at the outlet of scrubbing-cooling ring to verify the mathematical model. The velocity of jet hole and slot was obtained from experiment and simulation. The numerical simulation result fits the experimental result well. It suggests that vortex exists inside the scrubbing-cooling ring because of the structure of the ring. The motion of vortex is most violent along the circumference of inlet in the inner chamber

so that the average outlet velocity of jet hole at the circumference of inlet is the minimum and the velocity at the circumferential position between two inlets is the maximum. The distribution of average outlet velocity of slot at circumferential position is the same with that of jet hole.
