酸冷凝作用率是显著地表示酸冷凝作用罐头的酸腐蚀，和减小的一个重要因素在墙表面上减轻酸腐蚀剂效果并且改进设备的安全。在这研究，热转移和在发情 exchanger 的 finned 试管的酸冷凝作用的特征数字地被学习。在数字模型，我们由考虑 vaporliquid 平衡效果和多部件散开效果模仿了酸冷凝作用。把卵形的试管基于 H 类型 finned，我们建议了鳍的三种新奇类型提高热转移并且减少酸冷凝作用。煤气的温度，酸蒸汽集中，水蒸汽集中，和雷纳兹数字的参量的效果在不同的鳍结构上被调查。结果证明有新结构化的鳍的试管河岸能在热转移和酸反冷凝作用上改进表演。

英文摘要：

Acid condensation rate is an important factor denoting the acid corrosion, and the reduction of the acid condensation can significantly relieve the acid corrosive effect on the wall surface and improve the security of the equipments. In this study, the characteristics of both heat transfer and acid condensation of the finned tube in heat exchanger were numerically studied. In the numerical model, we simulated the acid condensation by considering the vapor-liquid equilibrium effect and multi-component diffusion effect. Based on the H-type finned oval tube, we proposed three novel types of fins to both enhance the heat transfer and reduce the acid condensation. The parametric effects of gas temperature, acid vapor concentration, water vapor concentration, and Reynolds number were investi- gated on different fin structures. The results show that the tube bank with the new structured fins can improve the performance on both heat transfer and acid anticondensation.
