Abstract

This paper briefly introduces particle image velocimetry (PIV) technology and summarizes the R&D of algorithms for PIV technology and its application and development in ship fields, including research into the flow fields around surface ships and underwater vehicles, as well as ship air flow fields. Finally, the development of PIV technology for ship fields is proposed. In terms of the speed measurement hardware system, PIV algorithms and ship flow field research, several problems requiring further study are put forward, providing new ideas for ship flow field research, and the development and application of PIV technology in ship fields is described. This study has certain reference and guiding significance for future research on flow field performance optimization.
