The optimization problems that must meet more than one objective are called multi-objective
optimization problems and may present several optimal solutions. This manuscript brings …

Aiming at the difficult problem of motion control of under-actuated and X-rudder autonomous
underwater vehicle (AUV), the present work adopts deep reinforcement learning (DRL) …

With the advancement of computing and inspired by optimal phenomena found in nature,
several algorithms capable of solving complex engineering problems have been developed …

Tidal energy, regarded as clean and renewable energy source, has received widespread
attention from scholars. As the basic structure of tidal power generator, the energy …

All hydraulic machinery has a tip clearance, which not only produces tip-leakage vortexes
(TLVs), but also reduces the energy performance of the machinery. In addition, tip clearance …

The analysis of flow field is essential for the fluid dynamics and the internal mechanism of
hydraulic machinery. The use of deep learning technology has revolutionized the field of …

Hydrofoils hold considerable academic and practical significance in the realms of marine
science, energy generation, and water-based engineering. They offer enhanced speed …

The transient process is widely existed in hydraulic machinery and engineering application,
which is closely related to the flow and noise characteristics. In the present work, the large …

The impact head, tip leakage vortex, and pressure pulsation during start-up can cause
vibration and noise in the pump, and affect its hydraulic performance. The linear speed start …

A crosshead slipper-guide system, which bears a significant thrust force, is an essential
friction pair in low-speed marine diesel engines. Owing to the low moving speed of the …
