Relationship between the Shape of Suspension Particle and Ground State Structure in Electrorheological Fluid

Taking account of the interaction among limited-distance neighbord chains, the effect of the shape osuspension particle in electrorheological (ER) fluid on the ground state structure of ER solid is discussed. The results of computation show that the ground state structure will change with the shape of suspension particle. Specially for flat ellipsoid particles suspended in a liquid the variation-value of interaction energy of the structure o ER solid changes in the range of 0.1~100.
