In this paper,we provide a Word Emotion Topic(WET) model to predict the complex word emotion information from text,and discover the distribution of emotions among different topics.A complex emotion is defined as the combination of one or more singular emotions from following 8 basic emotion categories:joy,love,expectation,surprise,anxiety,sorrow,anger and hate.We use a hierarchical Bayesian network to model the emotions and topics in the text.Both the complex emotions and topics are drawn from raw texts,without considering any complicated language features.Our experiment shows promising results of word emotion prediction,which outperforms the traditional parsing methods such as the Hidden Markov Model and the Conditional Random Fields(CRFs) on raw text.We also explore the topic distribution by examining the emotion topic variation in an emotion topic diagram.

A versatile numerical tool based on the open-source framework Open FOAM has been developed in this paper for modeling time-accurate,low-Mach number reacting flows,with a particular interest in small-scale flames.This tool consists of a gas-phase Navier-Stokes solver and a solid-wall heat conduction solver which can be implemented alone,or used together in a coupled means to reveal the small-scale combustion’s characteristics of significantly enhanced flame-wall thermal coupling.Validation works has proved that the tool is capable of reproducing experimental flames at various scales(from conventional to small scales),including well-recognized micro-flame features in literature such as three modes of premixed flame dynamics(weak flames,flames with repetitive extinction and ignition,and stable flames).Then,an experimentally-already-found but rarely-simulated unique phenomenon of diffusion flame street is successfully reproduced with well-captured flame structures.Moreover,the conjugate heat transfer model with the specific formulation of solid-wall heat conduction enables an attempt to simulate a novel,thermally-orthotropic combustor with its axial thermal conductivities superior to the transverse ones.Finally,computational performance of the developed Open FOAM solver is compared to that of the previously-used compressible flow solver Eilmer.The Open FOAM solver is found to show better wave-damping abilities for overcoming acoustic wave effects at the initial stage of simulations,and is much more efficient in terms of the computational cost.

通过以安徽省为案例构建混合动态可计算一般均衡模型,分析能耗双控优化以及转向碳双控的能源经济影响.研究发现,扣除新增可再生能源显著促进能耗双控政策支持可再生能源的作用并改善经济有效性,2035年可再生能源发电占比达到27.9%,而GDP损失降低0.2个百分点;转向碳双控政策会进一步促进可再生能源发展、腾挪能源消费空间并提高经济效率,GDP损失率进一步下降0.05个百分点;控制政策会产生赢家和输家行业,转向碳双控政策将会降低输家行业产出损失,2035年行业产出的变化率在-20.6%至10.3%之间.建议坚持实施能耗双控制度优化措施并在“十五五”时期向碳双控政策过渡,匹配以前瞻性的产业布局和必要的公正转型措施来降低产业调整的不利影响,在降低短期政策调整波动的同时促进中长期“双碳”目标实现.

以某医院的异型开敞屋盖为研究对象,分析了其周围的流场分布及平均风荷载的分布情况。采用Realizable k-ε湍流模型,根据屋盖的主要特征建立了相应的简化模型,并进行了模拟分析。结果表明,异型开敞屋盖与主体建筑之间存在特殊的位置关系,导致屋盖与后方建筑之间极易形成漩涡。当屋盖正面直接面对风向时,气流会受到堵塞效应的影响,使得屋盖迎风面的风荷载相对较小,此时体型系数约为0.1。当屋盖侧面朝向风向时,气流相对畅通,屋盖表面主要受到风吸力的作用。研究结果可为建筑方案的早期设计提供参考。

“Flame-street”is an interesting diffusion flame behavior in which a series of flame-segments is separately distributed along the mixing layer in a narrow channel.This experimental phenomenon was experimentally and numerically investigated with the focus on the steady-state,thermo-chemical flame structures in previous literature.In the present paper,the dynamic formation process of a methane-oxygen diffusion flame-street structure was simulated with a reacting flow solver developed based on the open-source framework OpenFOAM.By imposing a certain amount of ignition-energy near the channel outlet,a reaction-kernel was formed and bifurcated.Subsequently,three separate flames were consecutively generated from this kernel and propagated within the channel.The whole process was completed within 15 ms and all the discrete flames were eventually in a steady-state.Interestingly,different propagation features were observed for the three flame segments:The leading flame experienced a flame shape/type change from a tribrachial structure in its fastpropagating phase to a long,trailing diffusion tail after being anchored to the inlet.The successive flame had a much lower propagation speed,keeping its two wing-like(fuel-lean premixed and fuel-rich premixed)structure while moving toward its stabilization location,which was approximately in the middle of the channel.The last flame,after the ignition source was turned-off,was immediately convected a bit downstream,and eventually featured a similar two-branch-like structure as the second one.Moreover,chemical insights for the premixed and diffusion branches of the leading flame were also provided with the change of significance of some key elementary reactions focused on,in order to attain a detailed profiling of the flame-type transition.This paper is a first-ever one discussing the transient formation of flame-streets in literature and is believed to be useful for obtaining a comprehensive understanding of this unique flame characteristics from a dynamic point of view.
