【摘要】:在海洋科学领域,研究人员已开始使用一种新型传感器平台进行海洋数据采集,该设备在很大程度上增进了对复杂多变的海洋现象的研究与预测。这种新颖的设备能够在宽阔海域长时间进行数据采集。本文主要研究新开发的波浪式滑翔机平台,基于CFD数值仿真技术,对波浪滑翔机的运动进行模拟,研究其在不同浪级下的前进速度。研究表明:3级海况下,波浪滑翔机的平均速度可达到0.89 m/s;4级海况下,波浪滑翔机的平均速度可达到1.20 m/s,为精确预测海试波浪滑翔机的航速以及环境因素对其影响提供有力依据。
[Abstract]:In the field of marine science, researchers have begun to use a new sensor platform for marine data acquisition, which has greatly improved the research and prediction of complex and changeable marine phenomena. This novel equipment can collect data for a long time in a wide sea area. In this paper, the newly developed wave glider platform is studied. Based on CFD numerical simulation technology, the motion of wave glider is simulated, and its forward speed under different wave levels is studied. The results show that the average velocity of the wave glider can reach 0.89 m / s and the average velocity of the wave glider can reach 1.20 m under the sea condition of class 3, which provides a powerful basis for accurately predicting the speed of the sea test wave glider and the influence of environmental factors on it.
