“…Two-phase bubble flow, characterized by the dispersion of a gaseous phase in the form of discrete bubbles within a continuous liquid phase, is a fundamental phenomenon that finds extensive application in various industrial processes. This flow pattern, with gas bubbles typically smaller than the characteristic dimensions of the conduit, is commonly encountered in diverse industrial sectors, including steam generators [1], bubble columns [2], and piping systems [3].…”

A method based on the concept of eddy viscosities due to turbulence and bubble agitation is utilized along with appropriate correlations available in the literature in order to estimate the total pressure drop in a vertical bubbly flow. The method aims to minimize the experimental measurements required to calculate the pressure drop which remains the most significant quantity of engineering interest in fluid flows. It has been shown in this work through experimental comparisons that these correlations can make the procedure independent from the knowledge of experimental measurements and yet are able to estimate the total pressure drop with good accuracy.
