CO₂ emissions are a critical environmental concern driving global climate change, particularly the rise in Earth's average temperatures. Therefore, reducing CO₂ release into the atmosphere is essential. One promising...

Widespread attention has been drawn to the underwater biomimetic robotic fish due to its excellent agility and little environmental disturbance. A hybrid-driven bionic robotic fish outfitted with dual-propeller thrusters...

This study investigates two NOx-mitigation strategies, namely exhaust gas recirculation (EGR) and water–diesel emulsification, in a diesel–hydrogen dual-fuel compression ignition engine. A validated three-dimensional...

Pump-jet propulsors are widely used in marine applications because of their advantages in propulsive efficiency, cavitation performance, and low noise performance. However, the lack of a standard series database still li...

Underwater gas pipelines are vital for energy transportation but are often subjected to harsh environments, and any leakage can have significant environmental consequences. Substantial underestimation of gas plume format...

Unmanned surface vehicles (USVs) operating in open-sea environments experience significant roll motion due to wave-induced excitation. The dynamic roll response depends on various factors, including vessel speed, wave en...
