提高升阻比是实现水下滑翔机低功耗和远距离航行的重要手段之一。本文采用粘性流体理论，基于流体软件STAR-CCM+，数值模拟了典型水下滑翔机的升阻比变化。然后从压力和涡量分布规律2个角度对典型水下滑翔机模型进行研究，并对典型水下滑翔机模型进行了结构优化设计，做了数值模拟仿真验证。本文研究可以为后期水下滑翔机的结构改进及外形优化提供参考。
Improving lift-to-drag ratio is one of the crucial means to achieve low power consumption and long-distance navigation of underwater gliders. In this study, employing the theory of viscous fluid dynamics and utilizing the fluid software STAR-CCM+, the variation law of lift-to-drag ratio with angle of attack for a typical underwater glider is numerically simulated. Subsequently, from the perspectives of pressure distribution, streamline distribution, and vorticity distribution, structural optimization design of the typical underwater glider model is conducted, followed by numerical simulation and validation. This research can provide reference for the structural improvement and shape optimization of underwater gliders in the later stage.
