    Experimental Investigation of the Dynamic Deformation of Wind Turbine Blades Based on 3D-Digital Image Correlation by Liru Zhang, Jing Jia, Shibing Shao, Wei Gao, Dachuan Niu

    Published 2024-12-01
    “…The experimental results show that the dynamic waving deformation of the blade shows the trend of increasing and then decreasing with the increase in wind turbine rotational speed and incoming wind speed, and when the rotational speed reaches 500 r/min and the incoming wind speed reaches 9 m/s, the blade deformation reaches the maximum value; the dynamic waving deformation of wind turbine blade decreases with the increase in the elastic modulus of the blade and the degree of the decrease decreases gradually; the dynamic deformation of is predicted by the multiple displacement distribution of different blades under different operating conditions, and is obtained by the fitting of the experimental data. …”

    Enhanced Pool Boiling via Binder-Jetting 3D-Printed Porous Copper Structures: CHF and HTC Investigation by Lilian Aketch Okwiri, Takeshi Mochizuki, Kairi Koito, Noriaki Fukui, Koji Enoki

    Published 2025-07-01
    “…These improvements are attributed to the formation of distinct vapor–liquid pathways within the porous structures, which promotes the efficient rewetting of the heated surface through capillary action. This mechanism supports a highly efficient, self-sustaining boiling configuration, emphasizing the superior rewetting and vapor management capabilities of these 3D-printed porous structures, which extend the boundaries of sustained high heat flux performance. …”

    Analysis of detonation wave effect in radial water coupling blasting by Yanbing WANG, Weiwen KONG, Dongchen WANG, Youyi SHEN, Ajian FENG, Yang LI, Wenhai ZHENG

    Published 2024-12-01
    “…As the water coupling coefficient increases, the pressure on the borehole wall first increases and then decreases, and the energy transfer efficiency first decreases, then increases and then decreases; Due to the presence of water medium, water coupled charge blasting can effectively extend the duration of shock wave action and improve energy transfer efficiency; Compared to the concentric water coupling charge form, the eccentric water coupling charge has a significant eccentric stress field, which can significantly increase the peak pressure of the hole wall on the coupling side, reduce the energy attenuation efficiency, and improve the energy utilization rate. …”
