An Anti-Erosion Cylindrical Surface Incorporating Two Bionic Elements

Abstract Erosion is an inevitable and persistent form of wear, which predominantly occurs on curved surfaces within the realm of fluid machinery. To address this issue, we have developed a novel model incorporating two bionic elements, namely bionic arrangement and bionic morphology, and applied it to explore the erosion resistance of cylindrical surfaces. Specifically, the bionic arrangement is inspired by the phyllotaxis arrangement observed in plants, while the bionic morphology involves the incorporation of convex unit morphology found in desert organisms. Employing a comprehensive approach encompassing erosion testing and numerical analysis, we established two comparative test groups that differed in terms of arrangement and distribution density. This comprehensive analysis sheds light on the erosion resistance mechanism inherent in the combined bionic model. The findings of this study hold significant theoretical implications for the advancement of bionic anti-erosion technology and its practical applications in engineering.
