Influence of the void fraction profile on the distribution parameter C0 for a bubbly gas–liquid flow in a horizontal round pipe

This paper presents the results of a numerical experiment on the influence of the void fraction profile on the distribution parameter C0 in a horizontal bubbly two-phase flow. It was shown that for non-symmetric void fraction profiles, which occur normally in horizontal flows, the distribution parameter may be less than 1. In this case, the ratio of the volumetric flow quality β to the average void fraction 〈α〉 can also be less than 1.
