Small-scale wind energy harvesting using piezoelectric materials by Zhao, Liya

“…A two degree-of-freedom galloping piezoelectric energy harvester (GPEH) is proposed which successfully enhances the output power in low wind speeds. A beam stiffener is employed as an electromechanical coupling magnifier, which is proved to be an easy but greatly effective efficiency enhancing method for energy harvesting from VIV, flutter as well as galloping. …”

Large eddy simulations of turbulent circular wall jets by Zhang, Shuai, Law, Adrian Wing-Keung, Zhao, Bing

“…Overall, the study shows that LES coupling with proper near-wall modelling can simulate both the kinematic and mixing characteristics of the turbulent wall jet in a satisfactory manner, and the accuracy is superior to the RANS models with enhanced wall functions for this three-dimensional wall-bounded shear flow. The advantages can be attributed directly to the better simulations of the anisotropic jet spreading near the wall.…”

Self-organized canals enable long-range directed material transport in bacterial communities by Li, Ye, Liu, Shiqi, Zhang, Yingdan, Seng, Zi Jing, Xu, Haoran, Yang, Liang, Wu, Yilin

“…Using Pseudomonas aeruginosa colonies as a model system, we discover that a large-scale and temporally evolving open-channel system spontaneously develops in the colony via shear-induced banding. Fluid flows in the open channels support high-speed (up to 450 µm/s) transport of cells and outer membrane vesicles over centimeters, and help to eradicate colonies of a competing species Staphylococcus aureus. …”

Large-scale model testing of high-pressure grouting reinforcement for bedding slope with rapid-setting polyurethane by Zhang, Zhichao, Tang, Xuefeng, Liu, Kan, Ye, Longzhen, He, Xiang

“…Results show the great potential of polymer grout in improving bearing capacity, reducing settlement, and protecting slopes from being crushed under shearing. The polymer-treated slopes remained structurally intact, while the untreated slope exhibited considerable damage when subjected to loads surpassing the bearing capacity. …”
