Flow-induced coalescence in polydisperse systems

Popis výsledku v původním jazyce

The theory of flow-induced coalescence, based on the switch between the rates of approach of spherical and flattened droplets, is generalized to systems with different droplet radii. Probability, Pc, that the droplet collision will be followed by their fusion is calculated for systems containing droplets with two different droplet radii as a function of the average droplet radius. Analysis of the results obtained shows that Pc is a gradually decreasing function of the average droplet radius, (R) in broad range of (R) for systems with a large width of droplet radii distribution. The dependence of Pc for a polydisperse system should be considered also if experimentally determined average particle size is regarded as a result of the competition of the droplet breakup and coalescence in flowing polymer blends.
