Summary

Energy is an essential material basis for human survival and development, but faults and damages are inevitable during either fabrication or lifetime of energy equipment for energy production. In addition, the energy equipment usually presents complex dynamical behaviors. They influence the normal operation of energy equipment. Therefore, it is essential to study the dynamics and develop advanced techniques for ensuring the safe and reliable operation of energy equipment. Lots of academics have been committed to investigating and developing the dynamics, fault diagnosis, reliability, and quality control in the life cycle management of energy equipment. For this purpose, this special issue would collect the latest achievements in this field. Potential topics include but are not limited to:

Dynamics and fault diagnosis of equipment in traditional energy

    Effects of I-EGR and Pre-Injection on Performance of Gasoline Compression Ignition (GCI) at Low-Load Condition

    Binbin Yang, Leilei Liu, Yan Zhang, Jingyu Gong, Fan Zhang, Tiezhu Zhang
    Energy Engineering, Vol.120, No.10, pp. 2233-2250, 2023, DOI:10.32604/ee.2023.028898

    Abstract Gasoline compression ignition (GCI) has been considered as a promising combustion concept to yield ultra-low NOX and soot emissions while maintaining high thermal efficiency. However, how to improve the low-load performance becomes an urgent issue to be solved. In this paper, a GCI engine model was built to investigate the effects of internal EGR (i-EGR) and pre-injection on in-cylinder temperature, spatial concentration of mixture and OH radical, combustion and emission characteristics, and the control strategy for improving the combustion performance was further explored. The results showed an obvious expansion of the zone with an equivalence ratio… More >

    Automatic Extraction Method of Weld Weak Defect Features for Ultra-High Voltage Equipment

    Guanghua Zheng, Chaolin Luo, Mengen Shen, Wanzhong Lv, Wenbo Jiang, Weibo Yang
    Energy Engineering, Vol.120, No.4, pp. 985-1000, 2023, DOI:10.32604/ee.2023.024372

    Abstract To solve the problems of low precision of weak feature extraction, heavy reliance on labor and low efficiency of weak feature extraction in X-ray weld detection image of ultra-high voltage (UHV) equipment key parts, an automatic feature extraction algorithm is proposed. Firstly, the original weld image is denoised while retaining the characteristic information of weak defects by the proposed monostable stochastic resonance method. Then, binarization is achieved by combining Laplacian edge detection and Otsu threshold segmentation. Finally, the automatic identification of weld defect area is realized based on the sequential traversal of binary tree. Several More >
