WebJul 1, 2024 · Furthermore, the composite model is improved by introducing an additional condition to consider the overlapping region of the stretching and reflexive separation regimes at high Weber numbers. The outcome of a binary collision is identified based on the collision Weber number, the dimensionless impact parameter and the droplet size … WebDec 12, 2024 · A substantial amount of droplet collisions is expected near the spray nozzles, due to the high local droplet number density and relative velocity. The droplet size, velocity distribution and initial spray angle are significantly altered by the collision dynamics: coalescence of droplets will produce larger droplets, whereas separation will ...

WebFeb 25, 2014 · Three-dimensional binary droplet collisions are studied using a multiphase cascaded lattice Boltzmann method (LBM). With this model it is possible to simulate collisions with a Weber number of up to … WebAug 15, 2024 · Droplet collision is common in nature and industrial processes, while understanding of the phenomena at high Weber numbers is not as comprehensive as the one at low Weber numbers. We experimentally investigate the collision dynamics of two droplets at high W e ranging from 200 to 2000 by adopting pure water and pure ethanol … simple bath remodel photos
