| 摘 要： | 采用Fluent软件模拟了两种装置中的流场及温度场,并与工程实测结果进行比较。结果表明,采用渐变断面设计方式,烟气在换热面上分布更均匀,更有利于强化换热,阻力更小,节省材料和空间。实际应用表明该流动方式可有效降低噪声。

| Abstract: | Simulates the flow and temperature distribution in two schemes of devices by Fluent tool,and compares the result with those of site measured data from projects.The results show that the distribution of flue gas on heat exchanging surface is more uniform under the gradual changed section mode,beneficial to heat transfer enhancement,resistance reduction and less material consumption and space occupied.Actual application shows that the flow pattern can reduce noise effectively. |
