摘要

This study introduces an innovative methodology for simulating anguilliform swimming by combining a finite volume method with a coupled overset mesh and radial basis mesh (RBF) deformation technique. The overset mesh technology efficiently handles domain alterations resulting from forward motion, while the RBF mesh deformation method accommodates boundary deformations. Our approach’s robustness and accuracy are rigorously validated through comprehensive comparisons with both numerical and experimental results for self-propelled fish-like swimming. These comparisons unequivocally establish the precision and effectiveness of our methodology, highlighting its potential as a valuable tool for simulating and comprehending complex fluid dynamics in anguilliform swimming and other related fields.
