“…The analysis revealed that the presence of the texture decelerated the exposure of the surface to the fast flow field, resulting in a reduced surface area in contact with vortices, thereby enhancing the surface drag reduction performance. This finding aligns well with previous studies on textured surfaces for drag reduction purposes, , serving as a theoretical basis for selecting the semilunar microstructure in this study. Moreover, it was observed that the drag reduction effect of the semilunar microstructure was noticed in both concave and convex directions.…”

The nature always offers amazing inspiration, where it is highly desirable to endow coatings on marine equipment with powerful functions. An excellent example is slippery zone of Nepenthes pitcher, which possesses novel liquid-repellent and selfcleaning performance. Therefore, this study presents an efficient fabrication method to prepare a novel coating. The coatings were fabricated by designing biomimetic textures extracted from the lunate bodies of slippery zone on polydimethylsiloxane (PDMS) and then grafting Dictyophora indusiata polysaccharide (DIP) modifier. The as-prepared slippery coatings exhibited outstanding antifouling properties against kinds of daily life pollutants such as Chlorella and coffee. This synergistic strategy was proposed combined with environmentally friendly modifier grafting and heterogeneous microstructure on the surface to broaden new probabilities for manufacturing slippery coatings with incredible protective functionality.

Biomimetics, which draws inspiration from nature, has emerged as a key approach in the development of underwater vehicles. The integration of this approach with computational fluid dynamics (CFD) has further propelled research in this field. CFD, as an effective tool for dynamic analysis, contributes significantly to understanding and resolving complex fluid dynamic problems in underwater vehicles. Biomimetics seeks to harness innovative inspiration from the biological world. Through the imitation of the structure, behavior, and functions of organisms, biomimetics enables the creation of efficient and unique designs. These designs are aimed at enhancing the speed, reliability, and maneuverability of underwater vehicles, as well as reducing drag and noise. CFD technology, which is capable of precisely predicting and simulating fluid flow behaviors, plays a crucial role in optimizing the structural design of underwater vehicles, thereby significantly enhancing their hydrodynamic and kinematic performances. Combining biomimetics and CFD technology introduces a novel approach to underwater vehicle design and unveils broad prospects for research in natural science and engineering applications. Consequently, this paper aims to review the application of CFD technology in the biomimicry of underwater vehicles, with a primary focus on biomimetic propulsion, biomimetic drag reduction, and biomimetic noise reduction. Additionally, it explores the challenges faced in this field and anticipates future advancements.

“…For example, the tiny denticles on sharkskin change the velocity distribution in the turbulent boundary layer, contributing to the drag reduction and thus a high swimming velocity. [ 8‐9 ] The flexibility of the dolphin skin can absorb turbulent pulsations to postpone the laminar boundary layer to turbulent, [ 5,10‐11 ] achieving the drag reduction. Excellent drag‐reduction performances have also been demonstrated on other fishes, such as Carassius auratus and Dicentrarchus labrax .…”

Comprehensive SummaryIn nature, fishes have evolved functional skins with effective hydrodynamic performance and anti‐fouling, facilitating predation and escaping from predators. Although a large number of fish scale‐inspired structured surfaces have been explored, the incorporation of mucus on the structured surfaces has been largely ignored. Inspired by the skin of Osteichthyes fishes, a Janus hydrogel coating (JHC) is successfully prepared by a two‐step UV light irradiation at room temperature. The bottom side of JHC (STH) achieves a shear adhesive strength of 103.3 ± 17.5 kPa and can strongly adhere to a large variety of surfaces, including metals, ceramic and polymers. The top surface of JHC (SLH) replicates the structure of cycloid scales, while the nature of hydrogel mimics the mucus on fish skin. SLH possesses prominent mechanical, anti‐swelling, anti‐fouling and drag reduction properties. The design strategy for JHC has potential applications in numerous fields, like, pipeline transportation, bioengineering, and shipping industry.This article is protected by copyright.
