Reduced-order models (ROMs) offer an effective means to extract the dominant features of flow fields while significantly reducing computational resources, which provides an important means for the analysis and interpretation of nonlinear complex flow field information. Although ROMs have been widely applied to reconstruct fields of steady-state flows with different geometries or transient flows with one geometry, the study on reconstructing transient flow fields with different geometries remains limited. In this study, a novel flow field reconstruction method combining Proper Orthogonal Decomposition (POD) and Dynamic Mode Decomposition (DMD) is proposed, and then applied to reconstruct the wave field of a trimaran under different side hull layouts at a wave length equal to the ship length. The results indicate that the reconstructed flow fields exhibit lower errors compared with the original flow fields by high-fidelity simulation, which validates the reasonableness and feasibility of the proposed method, laying a solid foundation for subsequent studies on flow field prediction and optimization for hull forms.
