Potentials in D-C corona fields

Approximation and Reconstruction of the Electrostatic Field in Wire–Plate Precipitators by a Low-Order Model

“…In Figs. 3a and 3b, the potential distributions obtained with different meshes are compared with the experimental data of [21]. If we exclude the coarsest uniform grid, the results are independent of grid resolution, except for slight differences observed near the wire as shown in Fig.…”

“…In particular, we consider a wire-duct precipitator configuration that has been studied numerically (e.g., [7]) as well as experimentally [21]. This test case is characterized by A/m 2 .…”

Calibration of aspirator-type ion counters and measurement of unipolar charge densities

“…Measurements of the electric space potential between the parallel plates, in the presence of space charge , were made with a space potential probe very similar in design to one reported by Penney and Matick [24] and Matick [25]. A sketch of the probe with its nominal dimensions is shown in figure 9.…”

“…A sketch of the probe with its nominal dimensions is shown in figure 9. The operation of the probe is described briefly here; a full account is given in [24] and [25] .…”

“…The corona wires are oriented parallel to one another and are perpendicular to the plane of the figure Schematic view of space potential probe after Penney and Matick [24,25] Positive charge density measurements, p , as a function of average air velocity in plane of aperture. Calculated values of the charge density p , are shown assuming that y and z are 13.75 cm and 17 cm respectively.…”
