phase is larger than that of the continuous phase). As the Experiments were performed to elucidate the effects of simultadrops reach the bottom of the container, they coalesce into neous buoyancy-driven sedimentation and coalescence on the a segregated layer of the dispersed-phase fluid (Fig. 1b). drop-size distribution and phase separation of small drops of 1,2-This layer grows with time (Fig. 1c) until all of the dispersed propanediol dispersed in dibutyl sebacate. The phase-separation drops have coalesced into it (Fig. 1d). The problem is comrate and average drop size were observed to initially increase due plicated by the possibility that the drops also collide and to coalescence, and then to decrease due to the larger drops settling coalesce with each other as they sediment, and, because the out of the dispersion. The experimental results are in good larger drops move faster and leave the smaller ones behind, agreement with theoretical predictions based on inhomogeneous the drop-size distribution varies with both time and position.
