We investigate the structure and phase behavior of the Stockmayer fluid in the presence of nonuniform electric fields using molecular simulation. We find that an initially homogeneous vapor phase undergoes a local phase separation in a nonuniform field due to the combined effect of the field gradient and the fluid vapor-liquid equilibrium. This results in a high-density fluid condensing in the strong field region. The system polarization exhibits a strong field dependence due to the fluid condensation.
我们使用分子模拟研究了在非均匀电场存在下斯托克迈耶流体的结构和相行为。我们发现，由于场梯度和流体气液平衡的共同作用，初始均匀的气相在非均匀场中会发生局域相分离。这导致高密度流体在强场区域冷凝。由于流体冷凝，系统极化表现出强烈的场依赖性。
