Exploring the Purpose and Usage of Larkins Correlations for Multiphase Flow

Multiphase flow is a phenomenon in which two or more phases of a substance, such as gas and liquid, simultaneously flow through a conduit. This type of flow has a wide range of applications, including gas-liquid flows in pipes and oil-gas-water flows in wells. To better understand and predict the behavior of multiphase flows, researchers have developed empirical correlations, such as Larkins correlations, which are used to approximate the flow regime. The purpose of using Larkins correlations is to determine the flow regime in a given multiphase system (Heidari et al., 2022). These correlations are based on the dimensionless parameters of the flow, such as the Weber number and the Reynolds number, which can be determined from the properties of the phases and the flow conditions. Larkins correlations are used to calculate the relative velocities of the phases and the resulting flow regime. For example, it can be used to predict whether the flow is stratified (layers of different phases), homogeneous (mixed), or annular (dispersed). Additionally, Larkins correlations can be used to predict the potential pressure drop in a multiphase flow system  (Mishra, 2016). It has been found to be applicable in a. Cont…
