The energy dissipation in sheared coagulated sols

摘要: The observed energy dissipation in coagulated sols subjected to a shear flow can be explained by assuming that the basic units of are elastic flocs which slightly deformed during collisions because stretching particle bonds within floc few tenths nanometer. Liquid inside perforated structures is generally considered immobile, but deformation some internal liquid movement occurs. Although amount rather small, order 1%, it sufficient account for dissipation.
