Abstract :

碳中和背景下,氨-氢混合无碳燃料备受关注,但合成氨与氨分解制氢过程也存在着氨-氢混合燃爆的风险.目前对氨-氢燃烧爆炸详细机理的研究不够充分,传统的详细机理十分复杂,计算耗时过长.为了研究高压下氨-氢混合气体的燃烧爆炸特性,使用零维均质模型(即不考虑空间分布且物理和化学性质均为均匀的简化模型),采用带有误差传播的有向关系图(DRGEP)法简化现有的氨-氢燃烧爆炸详细机理,再通过敏感性分析得到基元反应较少的氨-氢燃烧爆炸简化机理.将简化机理与计算流体动力学(CFD)模型耦合,开展管道内氨-氢燃烧数值模拟.结果表明,简化机理在验证层流火焰速度和点火延迟时间等方面表现出良好的性能.在爆破压力为 59.61 atm 和 69.97 atm下,平均激波速度的相对误差低于 1.4%,精度较高;且与简化机理耦合的CFD模型节约了计算资源.研究成果有助于推动氨-氢燃烧CFD模拟技术的发展,可为氨-氢混合无碳燃料的燃烧过程及爆炸防控提供理论指导.

Abstract :

二甲醚(DME)作为燃料具有来源广、可再生和低碳等优点,已成为最具潜力的内燃机和燃气轮机替代燃料。然而,关于DME燃烧机理的研究仍然不够深入。通过使用带有误差传播和敏感性分析的有向关系图法(DRGEPSA)对现有的高压条件下的DME燃烧详细机理进行简化获得了骨架机理(Mech_191),然后通过调整指前因子对Mech_191进行优化获得了简化机理。将应用简化机理获得的指征DME燃烧的重要参数(点火延迟时间和层流火焰速度)的预测值与文献值进行了对比。结果表明,简化机理的预测值与文献值高度吻合,验证了该机理在模拟DME燃烧特性方面的有效性。此外,还发现部分关键反应(如·CH_3OCH_2的消耗反应)的确定对于准确获取重要燃烧参数有重要作用。

Abstract :

提出一种基于振动传感器的跨越油气管道意外载荷检测方法.基于阈值处理理论,构建阈值-模极大值去噪方法,将重心频率、均方频率和频率标准差作为判断油气管道运行状态的特征参数;通过搭建长输管道振动实验系统,采用外物撞击的方法模拟跨越油气管道的意外载荷,对振动信号进行降噪处理并提取特征参数.结果表明,与传统去噪法相比,本方法的信噪比和计算速度获得大幅提升;管道正常运行和外物撞击状态下振动信号的相关特征参数存在显著差异,说明振动信号作为跨越油气管道状态检测指标的有效性;振动信号相关特征参数随着信号源与传感器距离的增加而增加,而对管道输量不敏感;流体流向对振动信号有重要影响,信号源在传感器上游时,相关特征参数显著高于信号源在传感器下游的情况.

Study on the mechanism of sessile droplets evaporation enhanced by the electric field SCIE
期刊论文 | 2024 , 288 | CHEMICAL ENGINEERING SCIENCE
Abstract&Keyword Cite

Abstract :

The evaporation characteristics of a sessile droplet under a direct current electric field were numerically investigated, and a numerical model was developed based on the arbitrary Lagrange-Euler method, combining the flow, heat transfer, vapour transport, and electrostatic equations. The simulations were validated to be in good agreement with previously reported experiments. The results demonstrate that the electric field can enhance the evaporation of the sessile droplet with different evaporative cooling numbers (initial electric field intensity E0 = 280 kV & sdot;m  1; 32.9% decrease in the evaporation time for water) by the following three methods: increasing the surface area of the droplet evaporation (2.6%) through the electric-field-induced deformation, improving the heat transfer efficiency between the droplet and substrate (droplet average temperature increases by 2.3 K) through the internal vortex, and by enhancing the shearing effect on the vapour layer (450.3% increase in vapour diffusion distance dc) through the external vortex. Additionally, the evaporation of a sessile water droplet undergoing thermocapillary convection is further enhanced under the electric field (E0 = 280 kV & sdot;m  1; 20.0% decrease in the evaporation time). As the inhomogeneous temperature distribution inside the droplet was eliminated by thermocapillary convection, the evaporation efficiency was dominated by the increased surface area of the droplet evaporation and the enhanced shearing effect on the vapour layer. These results will provide a better understanding of the electro-hydrodynamic enhanced droplet evaporation.

水平管道中甲醇和汽油顺序输送过程混油规律研究

Abstract :

采用成品油管道顺序输送甲醇不仅可以拓展甲醇运输方式、降低运输成本,还能够提升管道运力、缓解现有成品油管道低输量难题,但目前成品油管道顺序输送甲醇工艺相关研究鲜有报道,技术的推广和应用受限。针对顺序输送过程中的混油问题,结合ALE(Arbitrary LagrangianEulerian)方法、流体控制方程以及物质传递方程,建立了甲醇和汽油顺序输送混油模型,分析了输送次序和管道流速对甲醇和汽油顺序输送过程中混油长度和混油浓度演化的影响规律。研究表明,该模型模拟的混油长度略短于VOF(流体体积)方法,在实际顺序输送过程中选择甲醇前行汽油后行的输送次序,能够有效缩短混油长度。研究结论可为成品油管道顺序输送甲醇工艺提供理论指导。

Abstract :

Carbon peaking and carbon neutrality are gaining global consensus, and carbon reduction in aviation is necessary and urgent. The main objective of this research paper is to map and analyze the knowledge graph of aviation carbon emissions research from a bibliometric perspective. Publications related to aviation carbon emissions indexed by Scopus for the period 1992 to 2021 were analyzed primarily using CiteSpace software. This paper presents a bibliometric analysis of current research progress from four perspectives: (1) descriptive analysis of publications, involving annual distribution, authors, and journals; (2) analysis of co-cited authors and their countries; (3) co-citation analysis of cited references; and (4) co-occurrence analysis of keywords. A series of domain knowledge maps were constructed to visualize the core of aviation carbon emissions research and to distill the research perspectives on aviation carbon emissions in the past 20 years. The latest and most important research results in the field obtained through the combing provide certain references for the research and development of aviation carbon emissions.

Characteristics of liquid loading with surfactant injection in hilly terrain pipeline SCIE
期刊论文 | 2023 , 140 | EXPERIMENTAL THERMAL AND FLUID SCIENCE
WoS CC Cited Count: 4
Abstract&Keyword Cite

Abstract :

Surfactant injection technology has recently been proposed as an alternative to mechanical pigging for liquid unloading from the wellhead to the surface gas gathering system. This study aimed to verify the effectiveness of the technology by experimentally evaluating the liquid loading characteristics of gas-liquid flow with a sur-factant at the undeveloped and developed flow positions of the uphill test section (10 degrees) of a hilly terrain pipeline. The inner diameter and length of the uphill test section were 50.0 mm and 16.0 m, respectively. The liquid and gas working fluids were deionized water or 250 ppm sodium dodecyl sulfate (SDS) surfactant solution and air with the superficial velocities of 0.001 to 0.010 m/s and 2.0 to 14.0 m/s. The liquid volume fraction and liquid holdup were measured using the image-quick closing valve method and wire mesh sensor method, respectively, and the liquid holdup data were visualized using the MATLAB program and Tecplot software. Owing to the effect of the surfactant, the flow range of low liquid loading increased significantly with the flow regime transition from intermittent flow to segregated flow. Because of the complex interaction between the morphology of the slug body and the foam formation, the fluctuation range and peak of liquid holdup and the liquid volume fraction decreased significantly in the intermittent flow. The liquid holdup fluctuation range and liquid volume fraction decreased to nearly zero, and a foam layer was formed and climbed up along the pipe wall in the segregated flow. The results and analyses are beneficial for improving the surfactant injection scheme and establishing a pre-diction model.
