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.
Underwater thermal glider takes advantage of the volume change of the phase change material during the phase change process as the driving force, and the ocean temperature difference condition directly determines its operation. Solving the phase change process of the phase change material under the condition of weak temperature difference and inverse temperature difference Based on this, the upper and lower bounds of the voyage of the underwater glider needed to complete the phase change process are obtained, ie the critical voyage, and finally the critical voyage is analyzed. Obstacle and alienation of the behavior of the variable materials make the corresponding increase or variation of the critical range of the underwater glider.
