| 英文摘要 | In engineering applications, there is a critical need for efficient yet relatively accurate computational methods to model the swimming performance of flexible bodies at medium to high Reynolds numbers. Traditional computational fluid dynamics methods, such as the immersed boundary method, often face limitations at high Reynolds numbers, while dynamic mesh methods are resource-intensive. Inspired by the simplicity and theoretical strengths of the inviscid panel method, this study proposes a modified panel method incorporating an equivalent drag model, enabling it to account for viscous effects. This modified method is validated against a self-propelled fish simulation driven by muscle-mimicking internal actuation and accounting for fully coupled fluid-structure interactions. By adjusting the body's stiffness, we explore different swimming modes, demonstrating the modified method's effectiveness across various Reynolds numbers. Comparative analysis with dynamic mesh results shows that the proposed panel method significantly improves on the classic panel method in calculating swimming performance, force distribution, and pressure characteristics, including the mean and phase of pressure responses. The effectiveness of the correction depends on accurately estimating the frictional drag coefficient, which must account for both body shape and the influence of different swimming modes. The modified model proposed in this study demonstrates good versatility in the low-stiffness case, which manifests as a carangiform swimming mode. However, at higher stiffness, where the fish adopts an anguilliform mode, both the pressure distribution and drag become more complex, requiring further adjustment of the correction coefficient. |
