Monthly Peak-Shaving Control Strategies and Economic Analysis of an Ice-Storage Air-Conditioning System for Metro Stations

The energy consumption and electricity cost of air-conditioning systems in metro stations keep rising with the expansion of rail transit. Ice thermal-energy storage (ITES) shifts cooling load to off-peak hours, yet existing studies mostly optimize ice-storage operation on a daily...

Research on Innovative Strategies of AIGC Empowering Corporate New Media Communication——Taking the Official WeChat Account "High-speed Rail Sifang" as an Example

Against the backdrop that AIGC has comprehensively reshaped the logic of media production, new media operated by state-owned enterprises engaged in high-end equipment manufacturing have long been plagued by practical bottlenecks, including low efficiency of content production, di...

Unsteady aerodynamics and underbody flow characteristics of high-speed trains with bogie covers at 400 km/h

Although high-speed train (HST) bogie covers effectively reduce aerodynamic drag, they raise safety concerns due to lift-induced oscillations caused by unsteady underbody flow. This study investigates the effects of various bogie covering structures on aerodynamic load pulsations...

Dual-Ligand Synergistic Construction of Double-Walled Cage Zn-MOFs: Methyl Modification Regulates Pore Size and Selective C2H2/CO2 Separation Performance

Due to the extremely similar molecular sizes and melting and boiling points of acetylene (C2H2) and carbon dioxide (CO2), their efficient separation and purification have long been significant challenges in the field of industrial purification. Based on the ligand construction st...
