Collective effects during the formation of child droplets as a result of puffing/micro-explosion of composite droplets

Puffing and micro-explosion are among the major phenomena behind industrial secondary atomization of composite droplets. These effects significantly reduce average size droplets formed during jet breakup to 5–10 times original droplet in case puffing 100–200 micro-explosion. The initial sizes (radii) ranged from 0.5 1.5 mm. Here we present research findings on collective formation child as a result puffing/micro-explosion We have analyzed characteristics micro-explosive fragmentation group three used two fuel blends: 90 vol% Diesel fuel, 10 water; water. Typical each were determined by shadowgraphy. number fragments practically do not change when distances between parent exceed 8–10 radii. In these conditions, integral acceptable agreement with those isolated With shorter droplets, there considerable differences Conditions recorded which or can occur collisions
