  text: An optical measuring technique is presented allowing the exact in-situ measurement
    of local particle flux densities in a confined channel flow by counting single
    particles penetrating an optically well defined measuring volume. This enables
    a precise flux determination up to the direct vicinity of planar walls. The measurement
    set-up and its calibration as well as the whole test facility are described in
    detail. This measurement technique is used to study the particle transport in
    electrostatic precipitators. Exemplarily, results of particle flux profiles as
    well as precipitation, as gained from balances of parts of the precipitator channel,
    are presented. Furthermore, the possibility to determine particle velocity fluctuations
    is demonstrated.

  text: Electro-hydrodynamic (EHD) flows are investigated theoretically and numerically
    in this paper and results are presented for the flow field in model electrostatic
    precipitators (EPs). The resulting flow fields are shown in various representations
    and explained qualitatively. Numerical calculations with different flow models
    (non-turbulent and RANS) were conducted to investigate the influence of the flow
    model on the resulting secondary flows. Furthermore, a perturbation analysis is
    presented, leading to a simple differential equation of the Helmholtz type. This
    allows a more detailed view of the important mechanisms forming the secondary
    flows as well as being able to obtain a very fast estimation of the resulting
    flow field. The calculations reveal a strong influence of a vortex formation at
    the beginning of the precipitation zone on the whole flow field. Furthermore,
    a strong effect of the boundary conditions of the electric field and the operating
    parameters is shown.
