Piezo stack energy harvesters with protection components for railway applications
(Elsevier, 9 May 2024)Piezo stack energy harvesting from railway vibrations shows substantial potential for powering wireless sensor networks responsible for monitoring railway infrastructure. Nevertheless, assuring the safety and durability ... -
Mechanical overload protection strategies for energy harvesters with frequency up-conversion mechanism
(Elsevier, 21 May 2024)Vibration energy harvesters utilising the frequency up-conversion mechanism have been effective in harvesting low-frequency ambient vibrations. However, the mechanical impact required for this process could also damage the ... -
Multi-point aerodynamic optimization of a backward-curved impeller fan
(American Society of Mechanical Engineers (ASME), 2024)Centrifugal fans find widespread application in building ventilation and air-conditioning systems. Nonetheless, they face challenges in meeting the growing need for energy efficiency, better performance, and reduced ... -
DFIG Driven Wind Turbine with Grid Supporting Battery Storage System
(Institute of Electrical and Electronics Engineers (IEEE), 2024)Grid operators face challenges with the increasing integration of wind energy into electric grids, necessitating uninterrupted wind power generation during outages to maintain system stability. Due to voltage dips there ... -
Experimental investigation on droplet evolutions in co-flow around the bluff body
(Elsevier, 21 November 2023)Annular mist flow widely exists in natural gas and other engineering fields. Vortex flowmeter has gradually become an effective means of wet gas measurement. However, the droplets in the flow field will influence the ...
