传输现象涉及三个密切相关的主题：动量传递（也称为流体动力学）、传热和传质。动量传递涉及动量的传递，传热涉及能量传递，质量传递涉及化学物质的传递。 1 热能储存系统中的传输现象通常涉及多个阶段和不同的规模。 2 图 2.1 是使用无机盐基复合相材料进行热能储存的示意图，说明了大长度尺度上的多相输运现象。在微观尺度上，如图 2.1 左下插图所示，人们旨在从颗粒结构和颗粒间力的角度了解质量、热量和动量输运的机制。这里的粒子在原子/分子尺度上可以非常小（B10±10 m），也可以在微粒尺度（B10±4 m）；
Transport phenomena refer to three closely related topics of momentum transfer (also termed fluid dynamics), heat transfer and mass transfer. Momentum transfer is concerned with transport of momentum, heat transfer deals with energy transport and mass transfer involves transport of chemical species. 1 Transport phenomena in a thermal energy storage system often involve multiple phases and different scales. 2 Figure 2.1 is a schematic diagram for the use of inorganic, salt-based, composite phase materials for thermal energy storage applications, illustrating the multiphase transport phenomena across a large length-scale.At the microscopic scale, as shown in the lower left inset in Figure 2.1, one aims to understand mechanisms of mass, heat and momentum transport in terms of particle structures and interparticle forces. Here the particles can be very small at an atomic/molecular scale (B10Ā10 m), and can be at a microparticle scale (B10Ā4 m);
