One of the most insightful methods for quantifying the performance of separators is a "partition analysis' . This detailed assessment is commonly performed using a "partition curve' . Partition curves show the probability of a particular particle having a given characteristics reporting to a given product stream.
For many separation applications, the main liquid entrainment mechanism is the shearing off of roll-wave crests (Fig. 5, Type 1). The onset of entrainment by this mechanism would be expected to coincide approximately with the wavy/annular transition shown in Fig. 3 and approximately with the transition from slug flow to annular flow.
