On the conductivity model for the electrorheological effect

摘要: A model is presented for the electric current and attractive force between two slightly conducting spherical particles in a nonpolar liquid. The includes nonlinear conductivity of liquid but does not require that zone be divided into distinct regions, nor there need to assume an equipotential condition at particle surface. Further, gives pertinent properties as function separation particles. Numerical values are ratio host oil (silicone oil), field, It shown good accord exists predicted yield stress measured on suspension zeolite silicone oil. Some also occurs density. Illustrated importance electrical parameter Ec ER response. Empirical equations shear modulus st...
