The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRACT

On the basis of the level set method, a new numerical method for predicting the evolution and the primary capillary breakup of a cylindrical liquid jet is presented. In such context, the only driving forces existed are considered to be the surface tension and the viscous forces, where the aerodynamic force is neglected. The evolution of the liquid jet and the subsequently dynamics including breakup are predicted by solving the Navier−Stokes equations using the control volume approach on a non-staggered grid system. The solution of the governing equations is performed only on the liquid phase, where specified boundary conditions for velocity components and pressure are defined on the moving interface. The topological changes of the moving interface is described via the level set method, which simultaneously, provides an accurate and robust modeling of the interfacial stresses which drive the internal flow. The numerical method is validated towards the analytical solution of the linear and nonlinear theories developed for predicting the evolution of the axisymmetric liquid jet under different conditions. The obtained results demonstrated the effects of the disturbance wave number, the disturbance amplitude, and the dynamics viscosity on the evolution and breakup of liquid jets. The formation of the satellite and sub-satellite droplets is also predicted which has been recognized as a highly nonlinear phenomenon in jet breakup process. The breakup process in the viscous regime is shown to be a self-repeating mechanism, which leads to the formation of sub-satellite droplets. The agreement with the analytical as well as the previous experimental measurements in inviscid and viscous regimes reveals the capability of the developed numerical method in predicting the liquids jet dynamics in different flow regimes.
