| Outline of Final Research Achievements |
As a basic study on mechanism of solidification and fluidization of non-crystalline materials, commonly encountered as foods and cosmetics, a theoretical investigation was performed on collective motions of particles in colloidal systems (typically consisting of numerous small particles dispersed in water). Application of methods borrowed from theories of fluid turbulence to colloidal systems has allowed construction of a theoretical framework for considering the directionality of motion of the particles, without causing inconsistency in regard to the relation between the endogenous and exogenous motions. As a result, a vortical motion of colloidal particles was successfully reproduced by the theory.
