摘要

作为核工业蒸汽系统中的关键除湿设备，瓦楞板干燥机的分离效率直接影响蒸汽质量和运行安全。该理论模型能够快速调整cpd设计优化中的参数，与实验测量和CFD模拟相比，效率显著提高。本研究基于液滴在CPDs不同截面的受力分析，建立了液滴运动模型。该模型将松香-拉姆勒液滴粒径分布与壁面碰撞检测算法相结合，开发了cpd分离效率预测程序。程序预测结果与实验数据吻合较好，分离效率最大偏差为5.4%。基于液滴在通道内的运动轨迹，研究了进口参数和结构参数对CPD分离效率的影响机理。

Study of Droplet motion behavior in corrugated-plate dryers

As a critical dehumidification device in the steam systems of the nuclear industry, the separation efficiency of corrugated-plate dryers influences steam quality and operational safety directly. The theoretical model enables rapid adjustment of parameters in the design optimization of CPDs, offering significantly higher efficiency compared to experimental measurements and CFD simulations. This study establishes a droplet motion model based on the force analysis of the droplet at different sections of CPDs. The model integrates the Rosin-Rammler droplet size distribution with a wall collision detection algorithm, and develops a predictive program for the separation efficiency of CPDs. The predicted results of the program show good consistency with experimental data, with a maximum deviation of 5.4 % in separation efficiency. The influence mechanism of inlet parameters and structural parameters on the separation efficiency of the CPD was studied based on the movement trajectory of droplets in the channel.

期刊介绍： Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field. Please note the following: 1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy. 2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc. 3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
