| 摘 要： | 水下热滑翔机利用相变材料发生相变过程时的体积变化作为驱动力,海洋温差条件直接决定了其工作情况.对相变材料在弱温差和逆温差条件下的相变过程进行求解,得出其相变规律,并以此为根据得出了完成相变过程所需的水下滑翔机航程的上限与下限,即临界航程,最后对临界航程进行分析,得出弱温差和逆温差对相变材料的行为阻碍和异化,使水下滑翔机临界航程范围相应的增加或变化异常.

| Abstract: | Thermal underwater glider takes the volume change as its driving force when phase change occurs in phase change material(PCM).Ocean thermal conditions directly determine the performance of PCM.By analyzing the phase change parameters under weak and inverse temperature condition,sailing range of thermal underwater glider to complete the phase change process(critical sailing range) is obtained.Finally,the result that weak and inverse temperature gradient will hinter and dissimilate the phase change process,an... |
