Basic two-phase flow measurements using 16N tagging techniques
- 1. Rensselaer Polytechnic Inst., Troy, NY
Description
A simple mixing model has been developed to analyze the fine structure observed in vertical slug-flow data obtained using 16N tagging techniques. This model assumes perfect mixing within the liquid slug for a steady-state, fully-developed, adiabatic, air/water slug-flow. It is shown that the normalized 16N concentrations in successive slugs follow a Poisson distribution. Experimental evidence is also presented for the disappearance of the laminar boundary layer near the pipe wall for a two-phase flow condition having a very small air flow
