RISFlow Pattern Transition During Gas Liquid Upflow Through Vertical Concentric Annuli—Part I: Experimental Investigations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present work, extensive experiments have been carried out on air-water upflow through concentric annuli to identify the distribution of the two phases in the bubbly, slug, and churn ...
Flow Pattern Transition During Gas Liquid Upflow Through Vertical Concentric Annuli—Part II: Mechanistic Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper the transition boundaries between different flow regimes during cocurrent upflow of gas liquid two-phase mixture through concentric annuli has been predicted theoretically. On the ...
