Transition from spray to roping in hydrocyclones

2018-7-1  Following the idea of Davailles et al., 2012, Chica et al., 2013 address the phenomenon with a mechanical energy balance approach. The main results for Newtonian suspensions showed that the dissipation of energy in the discharge of a hydrocyclone is very small compared with the dissipation in the hydrocyclone body and does not control the behavior of the hydrocyclone, but provides sufficient
