Two series of experiments, single-phase flow with liquid flow rates of 10–40 mL/min and two-phase flow with an identical overall flow rate range and gas volume transport fractions ranging from 0.125 to 0.50, were performed. From the instantaneous velocity vector maps, the mean and the root-mean-square velocities were computed, which allowed a systematic investigation of the single- and two-phase flow hydrodynamics and transport processes in the AFR. In single-phase flow, the velocity field is symmetric in the heart-shaped cells, and their particular design results in a stagnation zone that limits momentum exchange in each cell. The addition of the gas phase greatly increases the momentum exchange in the heart-shaped cells, which leads to a more uniform distribution of velocity fluctuations and increased transport processes within the AFR. date: 2015-08-05 date_type: published official_url: http://dx.doi.org/10.1021/acs.iecr.5b01444 oa_status: green full_text_type: pub primo: open primo_central: open_green verified: verified_manual elements_id: 1077165 doi: 10.1021/acs.iecr.5b01444 lyricists_name: Kuhn, Simon lyricists_id: SKUHN17 actors_name: Kuhn, Simon actors_name: Poirier, Elizabeth actors_id: SKUHN17 actors_id: EPPOI23 actors_role: owner actors_role: impersonator full_text_status: public publication: Industrial & Engineering Chemistry Research volume: 54 number: 30 pagerange: 7554-7564 issn: 1520-5045 citation: Wu, K-J; Nappo, V; Kuhn, S; (2015) Hydrodynamic Study of Single- and Two-Phase Flow in an Advanced-Flow Reactor.
