Flow fields in a straight, an orifice, a z- and a y-microchannel were investigated. Stationary particle tracking leads to the acting stresses. These stresses (tensile, shear, turbulent and compressive stress) are compared with the results of previously conducted dispersion experiments. Distributions of stresses and particle sizes were compared. Good agreement was found between experiments and simulations, but the predominant mechanism could not be identified.
