    Notes: Abstract A model for the description of saturation buildup curves on single-capture elements is presented. It avoids the principal difficulties connected with the so-called SEB model in the case of the transverse HGMS-geometry. The basic idea of this model consists of the “linking” of the normal and tangential components of the forces acting at the buildup surface by a force of static friction. In contrast to the SEB-model the fact that the saturation buildup surface is neither circular nor concentric with the cross section of the capture element is taken into account. After evaluating two sets of experimental data and calculating the coefficient of static frictionf the “model of static friction” is submitted to a first examination. Within the accuracy of these preliminary measurements and even with an approximate evaluation of the fluid drag force the usefulness of the proposed method is established.

    Particle accumulation on a single wire in transverse HGMS configuration (1987)

    Notes: Abstract An experimental investigation of particle accumulation on a single wire in the transverse HGMS configuration is presented. For saturation buildup we obtain a monotonic decrease of the coefficient of static frictionf sat with the flow velocityv a on the basis of the “friction model”. The power law of the dependence of the saturation accumulation area onv a , predicted by this model, is experimentally verified. Furthermore, we present an empirical law describing the dependence of the accumulation area on timeτ and on flow velocityv a for the entire buildup process. From the investigation of the initial accumulation we conclude that existing theories of the so-called capture radius do not satisfactorily describe the situation near the end of a capture wire.
