Study Of Flow Patterns And Void Fraction In Vertical Upward Two-Phase Flow

An extensive literature search on flow patterns, void fraction and experimental data for vertical upward two-phase flow was done. Experiments were carried out for flow visualization and void fraction data. Flow patterns and flow pattern transitions were studied. Flow pattern transition theories from literature were modeled and tested against experimental data. Effect of diameter and gas phase density on flow pattern map was studied. Variation of void fraction in flow patterns was studied. Flow pattern specific and flow pattern independent correlations from literature were tested against experimental data.Mechanical & Aerospace Engineerin
