Two-Phase Flow Regime Map Poster (Baker, Taitel-Dukler, Mandhane)

A two-phase flow regime map poster is a graphical tool used to predict and classify the dominant flow pattern (e.g., bubbly, slug, annular, or stratified) in horizontal or vertical pipes carrying gas–liquid mixtures, based on dimensionless parameters such as superficial velocities, fluid properties, and pipe geometry. It synthesizes empirical and mechanistic models—including the Baker, Taitel–Dukler, and Mandhane maps—to guide design and operation of multiphase systems. These maps partition the parameter space into distinct regions, each corresponding to a characteristic interfacial structure and transport behavior.

📖 Overview

Two-phase flow regime maps are foundational in multiphase flow analysis, enabling engineers to anticipate pressure drop, heat/mass transfer efficiency, flow stability, and equipment sizing requirements. The Baker map (1958), one of the earliest, uses liquid and gas viscosity–density ratios and superficial velocity ratios plotted on logarithmic axes, with region boundaries derived from experimental observations in vertical and horizontal pipes. The Taitel–Dukler map (1976) advances this by incorporating flow stability theory—distinguishing between stable and unstable regimes (e.g., stratified–smooth vs. stratified–wavy) using criteria for wave inception and transition, and is widely applied for horizontal flows. The Mandhane map (1974), built from a large database of air–water and air–oil experiments, offers empirically refined boundaries for verticaltems-start gap-2"> 📍 Weifang City, Shandong Province, China
