为研究高钠煤掺烧煤矸石抑制煤灰沾污结渣可行性,采用热重分析仪和固定床反应器考察了二者掺烧性能及掺烧对煤灰中Na保留的影响。通过掺烧前后灰渣中Na含量的差异,评价高钠煤掺烧煤矸石提高Na在灰渣中保留的可行性。通过对比理论和试验燃烧失重和质量变化速率,确定二者掺烧中协同转化性能。试验用高钠煤中的Na主要以水溶性、酸溶性和胺溶性钠为主,但燃烧前后均未检测到含钠化合物的晶体衍射峰。掺烧可显著提高灰渣中钠含量,当高钠煤燃烧中添加10%煤矸石时,灰渣中Na含量提高50%~75%,证实了掺烧煤矸石可实现燃烧中固钠。同时,掺烧提高了燃烧反应速率,降低了最大燃烧失重峰温,表现出明显的协同转化作用。通过进一步优化掺烧工况,有望实现高钠煤与煤矸石协同、高效、安全转化,达到节能减排目的。

Accurate prediction of server load is important to cloud systems for improving the resource utilization, reducing the energy consumption and guaranteeing the quality of service(QoS).This paper analyzes the features of cloud server load and the advantages and disadvantages of typical server load prediction algorithms, integrates the cloud model(CM) and the Markov chain(MC) together to realize a new CM-MC algorithm, and then proposes a new server load prediction algorithm based on CM-MC for cloud systems. The algorithm utilizes the historical data sample training method of the cloud model, and utilizes the Markov prediction theory to obtain the membership degree vector, based on which the weighted sum of the predicted values is used for the cloud model. The experiments show that the proposed prediction algorithm has higher prediction accuracy than other typical server load prediction algorithms, especially if the data has significant volatility. The proposed server load prediction algorithm based on CM-MC is suitable for cloud systems, and can help to reduce the energy consumption of cloud data centers.

International Journal of Extreme Manufacturing 2022年第4期4卷 246-259页

作者： Chengsong Shu qitong Su Minghao Li Zhenbin Wang Shaohui Yin Shuai Huang College of Mechanical and Vehicle Engineering Hunan UniversityChangsha 410082People’s Republic of China National Engineering Research Center for High Efficiency Grinding Hunan UniversityChangsha 410082People’s Republic of China

Droplet controllable manipulation over a wide temperature range has promising applications in microelectronic heat dissipation, inkjet printing, and high temperature microfluidic system. However, the fabrication of a platform for controllable droplet manipulation using the methods commonly used in industry remains a tremendously challenge. The popular method of controlling droplets is highly dependent on external energy input and has relatively poor controllability in terms of droplet motion behaviors and manipulation environment, such as distance, velocity, direction and a wide temperature range. Here, we report a facile and industrially applicable method for preparing Al superhydrophobic (S-phobic) surfaces, which enables controlled droplet bouncing, evaporation, and transport over a wide temperature range. Systematic mechanistic studies are also investigated. Extreme wettability surfaces were prepared on Al substrate by a composite process of electrochemical mask etching and micro-milling. To investigate the evaporation process and thermal coupling characteristics, controlled evaporation and controlled bouncing of droplet in a wide temperature range were conducted. Based on the evaporation regulation and bouncing mechanism of droplets on an extreme wettability surface, by using Laplace pressure gradients and temperature gradients, we realized controlled transport of droplets with confluence, split-flow, and gravity-resistant transport over a wide temperature range, offering a potential platform for a series of applications, such as new drug candidates and water collection.
