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

RESUMO

The theory of non-steady wave processes in two-phase gas-liquid media with bubble structure, including hierarchy structure of mathematical models of bubbly liquids dynamic behavior, has been developed. The models differ in the degree of accounting the effects of pressure, temperature and phase velocities non-coincidence in the process of dynamic deformation. Estimations of the influence of dynamic and heat interaction between gas and liquid on shock waves evolution have presented. The technique of the worked out models program realization has been proposed. All models have been realized on a computer. A considerable number of computational experiments has been carried out, resulting in defining the principal mechanisms determining shock waves evolution in bubbly liquids in a wide range of parameters. In particular, it has been shown that shock waves evolution in low-viscous liquids with bubble size about 1 mm is determined by heat dissipation resulting from non-equilibrium heat transfer between the gas in the bubbles and surrounding liquid. Thermophysics characteristics of the gas, insignificant in volume and still more insignificant in mass, play the decisive role on evolution and formation of oscillar and monotonous wave configuration. It has been discovered that at waves propagation there may be observed their amplification as a result of the presence of locative deformation inertia characteristics in the bubbly system. The mechanism and peculiarity of shock waves amplification have been studied. The analysis of other experimental data contained in literature has been carried out. The comparison of the calculated and experimental data has proved correctness of the worked-out theory.
