Abstract

The dynamics of the structure formation of an electrorheological fluid consisting of either one type of particles or with two types of particles is studied numerically. In the latter case half of the suspension particles have dielectric constants greater and the the other half smaller than that of the base fluid. In such a system the potential energy between interacting particles depends also on the type of the particles such that the direction of the force between different types of particles is complementary to the force between identical particles. The simulation model is based on a dipolemodel by utilizing an Ewald method for taking long range interactions intoaccount. The dipoles are not fixed but they are allowed to adapt to local surroundings.
