| 摘 要： | 在温跃层强度较低的弱温差层中,水下热滑翔机的相变材料的相变过程会受到阻碍,从而影响滑翔机性能。为了保证水下热滑翔机能够正常工作,通过对滑翔机的相变材料的相变过程和临界航程进行数值求解,分析不同的水平管半径和纵向速度对滑翔机的性能的影响,得出较小的水平管半径和较低的纵向速度可以有效地克服弱温差层下水下热滑翔机性能的恶化。

| Abstract: | The performance of phase change material （PCM） in underwater thermal glider is influenced by the condition of seawater temperature and the gliding posture of the glider. The weak temperature gradient will weaken the phase change process, and the performance of the glider will be influenced accordingly. By analyzing the phase change parameter and critical sailing range under different diameter of horizontal pipe and longitudinal velocity of glider, the performance analysis was taken. The result was given that small diameter of horizontal pipe and longitudinal velocity can overcome the influence to the thermal underwa- ter glider under the low temperature condition. |
