Mitigation of infusion and cure‐induced defects for thick thermosetting composites: Current challenges and future trends

Polymer Composites, Volume 46, Issue S1, Page S9-S25, 10 September 2025.
Typical manufacturing defects and mitigation strategies in thick thermosetting composites. Abstract The composite part industry is currently dominated by thin‐section geometries. However, thick composites gain interest in many applications where monolithic parts are required, such as foils, wind mill root blades, and so forth.

Study on the Temporal and Spatial Evolution Mechanism of Rotating Cavitation in the First Stage Impeller of LNG Submersible Pump With Two‐Stage Splitter Blades

Energy Science &Engineering, Volume 13, Issue 9, Page 4356-4370, September 2025.
ABSTRACT This study establishes a full‐flow passage numerical model of an LNG submerged pump equipped with two‐stage splitter blades through three‐dimensional modeling. Numerical simulations validated by liquid nitrogen experiments demonstrate that at 1.4 times the design flow rate, the peak efficiency reaches 60.6%, with a maximum head of 194.93 m ...

Cavitation generation and inhibition. II. Invisible tail wing of cloud cavitation and non-cavitation control mechanism

AIP Advances, 2021
The cloud-cavitation shedding mechanism was numerically investigated around the NACA 0015 hydrofoil of α = 7° and σ = 0.7, 0.67 under the identical computational conditions as in Paper I [W. Jin, AIP Adv. 11, 065028 (2021)].

Flow Memory Effect on Open‐Frame Remotely Operated Vehicle Motion

Journal of Field Robotics, Volume 42, Issue 6, Page 2611-2638, September 2025.
ABSTRACT The flow memory effect is a kind of viscous force caused by acceleration between continuous phases and underwater vehicles and the development of the boundary layer near the interfacial surface. This paper establishes a 6‐degrees‐of‐freedom unsteady equation of motion describing the flow memory effect on viscous hydrodynamic loads.

Research on swimming hydrodynamics based on a three‐dimensional high‐precision fish model

River, Volume 4, Issue 3, Page 341-350, August 2025.
Abstract Fish swimming hydrodynamics serves as a critical foundation for aquatic ecological conservation, with recent research extending from 2D to 3D perspectives. This study employs 3D high‐fidelity modeling with dynamic mesh technology to investigate how cylindrical obstacles at varying positions affect Carassius auratus locomotion. Analysis of nine

Signal noise estimation and removal of sub‐mm 3D pavement texture data using 1D residual denoising network

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 20, Page 3033-3052, 18 August 2025.
Abstract Signal noise removal is an indispensable and critical procedure in obtaining clean pavement texture data for reliable pavement evaluation and management. Nevertheless, the presently established denoising approaches to pavement texture data still rely on traditional techniques that have long struggled with removing noise accurately and ...

Unsteady Hydrofoil Theory

Journal of Zosen Kiokai, 1962
Present paper is aimed to predict theoretically the lift, moment and energy of wake vortex on the submerged hydrofoil moving close to the free surface under waves.Satisfying the boundary condition on the free surface, velocity potential is obtained for the bound and free vortex, from which the induced velocity field can be determined. From the boundary

Wakesurfing, Wakeboarding, and Waterskiing: A Comparison of Wake Characteristics

River Research and Applications, Volume 41, Issue 6, Page 1189-1206, July 2025.
ABSTRACT Waterskiing has been a commonplace and generally well‐accepted activity on inland waterways for many decades. More recently, there has been a significant increase in wakeboarding and wakesurfing, with the latter relying heavily upon “enhanced” boat wake.

Backward swimming in elongated‐bodied abyssal demersal fishes: Synaphobranchidae, Macrouridae, and Ophidiidae

Journal of Fish Biology, Volume 107, Issue 1, Page 52-62, July 2025.
Abstract The deep‐sea demersal fish fauna is characterized by a prevalence of elongated‐body forms with long tapering tails. Using baited camera landers at depths of 4500–6300 m in the Pacific Ocean, we observed multiple instances of backward swimming using reverse undulation of the slender body in four species: the cutthroat eel Ilyophis robinsae ...
