DESIGN OF A NOVEL AUV HULL SHAPE FOR IMPROVING HYDRODYNAMIC PERFORMANCE USING CFD
Nội dung chính của bài viết
Tóm tắt
This topic presents the results of the design new hull form for an Autonomous Underwater Vehicle (AUV) to improve hydrodynamic performance, reduce resistance, and enhance operational energy efficiency. The proposed shape is designed based on biomimetic principles to optimize flow characteristics, improve flow attachment, and reduce wake intensity behind the AUV hull. A commercial Computational Fluid Dynamics (CFD) software is employed to evaluate the hydrodynamic performance of several proposed AUV hull configurations. The numerical analysis focuses on resistance components, pressure distributions, and flow-field structures under steady operating conditions. The results demonstrate that the newly developed hull form achieves a significant reduction in total resistance, together with a more uniform pressure distribution and reduced flow separation in the stern region. These improvements contribute to improved hydrodynamic performance, reduced resistance characteristics, and enhanced operational efficiency of the AUV. The study also demonstrates the applicability of CFD as an effective numerical approach for analyzing and optimizing AUV hull configurations, thereby providing useful insights for the design and development of high-performance underwater vehicles operating under complex marine conditions.
