Summary: This study investigated the wake field of the flexible oscillating caudal fin using a Digital Particle Image Velocity (DPIV) system, presenting distributions of vorticity with different Strouhal numbers and calculating the velocity circulation of the vortex ring. A three-dimensional vortex ring chain model was introduced, and a conversion model between velocity circulation and dynamic moment of the vortex ring was presented. Comparisons of thrust force conversion results and a tricomponent balance system showed relative errors of 5.86% and 3.44%, respectively, demonstrating the accuracy and reliability of the thrust force conversion model for flexible oscillating caudal fins.

Summary: The study explores the hydrodynamics of swimmers with different caudal fins, noting a transition in propulsive mechanisms with increasing aspect ratio. While suction-based propulsion is generally considered efficient in animal swimming, the research finds that high aspect ratio caudal fins utilizing suction-based propulsion may reduce swimming efficiency. Factors beyond suction propulsion may also impact swimming efficiency.

Summary: Inspired by the excellent swimming performances of live fish, scientists and engineers are developing biomimetic robotic fishes with simpler and more robust mechanisms to better mimic their natural counterparts and exhibit improved swimming performances. Challenges lie in making the robotic fishes more realistic and expanding their applications in areas where conventional propellers are not suitable.

Summary: Underwater navigation in complex environments requires highly maneuverable propulsion mechanisms. Conventional propulsors often lack the adequate torque and force for maneuvering in such environments, but elongated fin propulsion can overcome these limitations. In this study, we tested and implemented three collision avoidance strategies using a robotic vessel equipped with elongated fin propulsion. We found that a circular sensing envelope in the robotic vessel allows for smooth transition to the mission path after collision avoidance, though it may result in longer distances to return to the desired path. Selecting the appropriate collision avoidance strategy depends on factors such as sensing capabilities, reaction time, turning rate, and objects to avoid. This work lays the foundation for utilizing complex maneuver techniques and undulating fin propulsion to achieve fish-like elegant maneuvers for underwater vessels.

Summary: This paper numerically studied the effects of flexibility and shape on the performance of a bioinspired panel. It found that within a certain phase lag range, flexible panels can significantly improve performance. Additionally, it discovered that convex shape is optimal for thrust generation, while square shape is optimal for propulsive efficiency.

Summary: Studies have shown that hydrodynamic interactions between fish median fins can improve swimming performance by enhancing leading-edge vortices on the trailing fin. Additionally, having fins arranged in tandem on an undulating body can lead to more steady production of thrust forces, but out of phase fin motion can decrease swimming speed.

Summary: This paper investigates the hydrodynamic performance of a virtual underwater vehicle under self-yaw, focusing on the fluid laws behind the plane motion achieved by bionic flexibility, particularly the flexibility of the caudal fin. The kinematics of the flexible body and fin are explored using dynamic mesh technology and user-defined functions. The study applies the 3-D Navier-Stokes equations to simulate the fluid surrounding the bionic dolphin and focuses on quantitative problems related to speed, energy loss, and working efficiency. The results show that self-yaw involves autonomous propulsion and active steering, with the degree of fin flexibility affecting yaw effects.

Summary: This study investigated the impact of vitamin C supplementation on the growth performance and fin regeneration rates of zebrafish. Higher dietary concentrations of vitamin C led to improved tissue regeneration in zebrafish. Based on regression analysis, the optimal vitamin C requirements for growth and tissue regeneration were determined for juvenile zebrafish fed practical diets for 60 days.

Summary: Tails, as a defining characteristic of chordates, exhibit enormous diversity in form and function across different species. Despite this diversity, tails have not received the same level of scientific attention as other body parts, highlighting the importance of interdisciplinary approaches in advancing tail research. Embracing a holistic understanding of tail evolution and function requires combining traditional and new experimental approaches within various research areas.

Summary: Modernfish, representing over 400 million years of evolutionary processes, have developed phenotypes with specific performance advantages for tasks like evading predation and securing food. Through careful analysis of biological properties, bioinspired technologies aiming to achieve similar objectives can be developed quickly. By exploring the performance space of different morphologies, bioinspired designs can also provide insights into evolutionary processes. Collaborations across disciplines can lead to the development of novel bioinspired technologies that not only function well as robotic devices, but also enhance our understanding of biology and the rules of life.
