“…In recent years, many researchers from both academic and industry have focused on utilizing wind [1][2][3][4], solar [5][6][7], tidal [8,9], and geothermal energies [10][11][12] to alleviate the serious energy crisis and environmental pollution. It is worth noting that harvesting the kinetic energy from human body to power portable electronic devices is a hot research topic in the last decade, such as converting the energy of the knee [13,14], waist [15,16], foot [17], wrist [18], and breathing [19] into electrical energy.…”

This paper presents an asymmetric magnetic coupling piezoelectric energy harvester based on galloping to scavenge low-speed wind. The piezoelectric beam of energy harvester undergoes bending and torsional vibration simultaneously due to the eccentric distance. By analyzing the kinetic energy, potential energy, and virtual work of the energy harvesting system, the mathematical model of harvester is constructed and verified by experiments. The optimal external load resistance is confirmed at different eccentric distances and wind speeds by experiments. Compared with traditional galloping piezoelectric energy harvester, the asymmetric with magnetically coupling galloping piezoelectric energy harvester has a lower threshold wind speed, i.e. 2 m/s. And the asymmetric configuration contributes to a lower natural frequency and electromechanical coupling coefficient, which results in a lower power and voltage output. The potential energy of harvesting systems at different distances between two magnets are respectively numerical analyzed in detail. The theorical results illustrate that the energy harvester operates in monostable and bistable at different magnet distances. And the threshold wind speed of energy harvester increases when the energy harvester works at bistable. According to the above analysis, this work provides a detailed guideline for mathematical modeling and performance improvement of asymmetric piezoelectric energy harvester based on galloping.

“…It is important for developing and utilizing crude oil in the pores of low permeability reservoir rocks. In terms of energy storage, compressed air energy storage in aquifers (CAESA) is a widespread low-cost application in large-scale energy storage technology [2] . CAESA requires injecting compressed air into the aquifer deep in the ground.…”

The interactions between gas and liquid have an important role in energy extraction and storage. For example, the interfacial tension (IFT) between the two phases has an important effect on developing crude oil in low-permeability reservoirs and compressed air energy storage in aquifers (CAESA). For the mechanism of two-phase fluid interaction in energy extraction and storage, the study of gas-liquid interface properties is carried out in the paper. Firstly, molecular dynamics simulations are used to study the molecular simulation progress of nitrogen and water under different environmental conditions, and the effects of different temperatures and pressures on IFT are studied. The results show that IFT increases with the temperature increase at constant pressure. When the temperature is constant, an increase in the pressure of the system will decrease the surface tension of the system. Then the effect of IFT on the distribution of gas-liquid phases in the pores of low-permeability rocks is studied by digital core technology and simulation methods. The results show that the lower the IFT of gas and liquid is, the better the displacement effect is and the higher the recovery ratio is in the low-permeability rocks. This study analyzes the IFT and influencing factors between the gas-liquid two-phase interface, and it guides the efficient development and utilization of energy extraction and energy storage.
