Characteristics of phase distribution of gas-liquid two-phase flow in new scrubbing-cooling chamber
The bubbly flow parameters,such as phase fraction and bubble diameter in the bubble column of a new type scrubbing-cooling chamber were measured by a double-sensor probe.A numerical model of the phase profile of gas-liquid two-phase flow in this scrubbing-cooling chamber was established by the software Fluent.The simulation results agreed with the experimental data.The research indicated that the inner component in this scrubbing-cooling chamber affected the gas-liquid two-phase distribution in the bubble column obviously.Compared with the GE-Texaco technology,the distribution of gas phase concentration in this chamber was more uniform,the liquid surface was more stable,the outlet gas entrainment was also controlled well,and the flexibility of operation was much better.
