Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Resistivity Change Mechanism in the Carbon Dioxide Sequestration Process
This study explores the variation law, influencing factors, and mechanisms of resistivity in the interaction between CO₂ and saltwater. This study used a hollow PEEK conductor to simulate core pores. With excellent thermal stability, mechanical strength, and electrical insulation, its homogeneous, nonporous nature eliminates interference from rock ...

Research on the Mechanism of Sand Bridge Stuck Drill in Deep Coal and Rock Gas Horizontal Wells
Accounting for wellbore collapse debris and the bulldozer effect, this study develops models for permeable and impermeable sand bridge sticking in deep CBM horizontal wells, deriving resistance and volume formulations. Validated in Changqing, results show impermeable bridges dominate; controls (fluid optimization, staged drilling, circulation, speed ...

Noise, Vibration, and Harshness (NVH) Challenges in Hydrogen Internal Combustion Engine Vehicles
ABSTRACT This paper presents a state‐of‐the‐art literature review on noise, vibration, and harshness (NVH) in hydrogen‐fuelled internal combustion engines. Studies published between 2011 and 2025 were screened, covering fundamental flame physics, test‐bench work, and recent prototype vehicles.
