Abstract

The structural parameters of wire mesh mist eliminator directly affect the separation performance. In this study, based on numerical simulation data, a mathematical model of separation efficiency and pressure drop was constructed by response surface methodology (RSM). Combined with the Non-dominated sorting genetic algorithm II (NSGA-II), the multi-objective optimization was carried out. The correlations of four structural parameters, namely, wire diameter, mesh diameter, layer spacing and number of layers, with separation efficiency and pressure drop was analyzed by Pearson’s coefficient. The results show that the number of layers significantly influences separation efficiency and pressure drop. Reducing wire diameter can increase separation efficiency and decrease pressure drop. The Pareto front solution set shows the trade-off relationship between separation efficiency and pressure drop, providing diverse design options for different engineering requirements. This study provides theoretical basis and methodological support for the design and optimization of wire mesh mist eliminators.

基于RSM和NSGA-II的丝网除雾器多目标优化研究

丝网除雾器的结构参数直接影响分离性能。在数值模拟数据的基础上，利用响应面法（RSM）建立了分离效率与压降的数学模型。结合非支配排序遗传算法II （NSGA-II）进行多目标优化。采用Pearson’s系数分析了丝径、网径、层间距、层数等4个结构参数与分离效率和压降的相关性。结果表明，层数对分离效率和压降有显著影响。减小丝径可以提高分离效率，减小压降。Pareto前解集显示了分离效率和压降之间的权衡关系，为不同的工程要求提供了多种设计方案。该研究为钢丝网除雾器的设计与优化提供了理论依据和方法支持。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
