    Abstract: Methods described herein provide a way to reduce or eliminate drag and adhesion of a substance flowing over a surface by creating a vapor cushion via evaporation of a phase-changing material of or on the surface or encapsulated within textures of the surface. The vapor cushion causes the flowing substance to be suspended over the surface, greatly reducing friction, drag, and adhesion between the flowing substance and the surface. The temperature of the flowing substance is above the sublimation point and/or melting point of the phase-changing material. The phase-changing material undergoes a phase change (evaporation or sublimation) upon contact with the flowing substance due to local heat transfer from the flowing substance to the material, generating a vapor cushion between the solid or liquid material and the flowing substance.

    Abstract translation: 本文所述的方法提供了一种减少或消除流过表面的物质的阻力和粘附的方法，其通过蒸发表面上或表面上的相变材料或封装在表面的纹理内而产生蒸气垫。 蒸汽垫使流动物质悬浮在表面上，大大降低了流动物质与表面之间的摩擦，阻力和粘附力。 流动物质的温度高于相变材料的升华点和/或熔点。 与流动物质接触时，相变材料由于从流动物质到材料的局部热传递而经历相变（蒸发或升华），在固体或液体物质与流动物质之间产生蒸气垫。
