algorithm reveal a sharper change in the conductivity dis-
tribution, aligning with expectations for water-air flows in
a hydrocyclone. In contrast, the GN one-step algorithm
produces conductivity profiles with a more diffusive nature
near the air-water interface.
The Effect of Spigot Diameter on Air-core Size:
This section is focused on investigating the impact of spigot
diameter variation under a constant pressure of 25 psi, spe-
cifically analyzing the performance of image reconstruction
algorithms on air-core diameter for spigot diameter sizes

of 12.5mm and 15mm. Radial profiles were presented to
provide a more precise analysis of the results, depicting the
average magnitude of pixel data at radially positioned pixels
of reconstruction profiles. As the spigot diameter increases,
there is an observable expansion of the low-pressure region
within the occupied area. Figure 4 (a) illustrates the radial
profiles of mean pixel magnitude representing the air core
fraction for different spigot diameters reconstructed by the
RBO method. Figure 4 (b) presents the estimated radial
profiles corresponding to GN one step. Both profiles are
consistent with theoretical expectations an increase in
