所观察到的能量耗散在凝结溶胶受到剪切流可以解释为假设流动的基本单位是弹性絮凝物，这是轻微变形的碰撞过程中，因为在絮凝物内的颗粒键拉伸了几十纳米。穿孔结构内的液体通常被认为是不动的，但在絮凝体变形期间，会发生一些内部液体运动。虽然内部液体运动的量相当小，约为1%，但足以解释所观察到的能量耗散。
The observed energy dissipation in coagulated sols subjected to a shear flow can be explained by assuming that the basic units of flow are elastic flocs which are slightly deformed during collisions because of the stretching of the particle bonds within a floc by a few tenths of a nanometer. Liquid inside perforated structures is generally considered immobile, but during the deformation of the flocs some internal liquid movement occurs. Although the amount of internal liquid movement is rather small, of the order of 1%, it is sufficient to account for the observed energy dissipation.
