Numerical investigation on thermal-fractional characteristics inside a heated tube enhanced with a novel grooved cone turbulator by Bing Mei, Azher M. Abed, Pinank Patel, Ankit Kedia, Hamdi Ayed, Abir Mouldi, Ibrahim Mahariq

“…To investigate the impact of the GCT's geometric characteristics on hydrothermal parameters, tests were conducted on varying groove diameters (2.5–10 mm), twist angles (0–270°), and pitch lengths (40–70 mm). The results demonstrate that heat transfer is directly correlated with both groove diameter and twist angle, while it is inversely correlated with pitch length. …”

Real-time helium bubble growth in tungsten by in-situ GISAXS by L. Corso, S. Curiotto, F. Cheynis, P. Muller, E. Bernard, M. Cabie, C. Martin, F. Leroy

“…To address the effects of He irradiation, we have studied in real time, during He bombardment at 1273 K, the nucleation and growth of He bubbles nearby the surface of tungsten by grazing incidence small angle X-ray scattering (GISAXS). We could disentangle the surface and bubble contributions on the measured GISAXS patterns by adjusting the X-ray incident angle below and above the critical angle of total external reflection. …”

Study on the Fracture Behavior of Cracks Emanating from Tunnel Spandrel under Blasting Loads by Using TMCSC Specimens by Bang Liu, Zheming Zhu, Ruifeng Liu, Lei Zhou, Duanying Wan

“…The results show that (1) crack inclination angles affect crack initiation angles and crack propagation lengths significantly; (2) critical SIFs of both mode I and mode II decrease gradually with the increase of the crack propagation speed; (3) the dynamic energy release rates vary during crack propagation; and (4) there are “crack arrest points” on the crack propagation paths in which the crack propagation speed is very small.…”

Collapse-Pounding Dynamic Responses of Adjacent Frame Structures under Earthquake Action by Wei Jing, Shangshang Xing, Yu Song

“…The results show that the impact force is larger when the weak column of the 8-story frame is close to the top of the 6-story frame; pounding increases the interlayer displacement angle of the 8-story frame and decreases the interlayer displacement angle of the 6-story frame in general; the impact force decreases first, then increases, and after that decreases with the increase of gap size; and the interlayer displacement angle distribution of the 6-story frame is significantly affected after the collapse-pounding of the 8-story frame with a weak column. …”
