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: 0.7 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: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

摘要

In the framework of the Zel'dovich-Novozhilov theory, limit cycles for solid propellant burning rate at constant pressure are investigated. The zeroth and the first two oscillation modes are involved in the analytical study. The equations for the mode amplitudes and frequency of the limit cycle occurring near the intrinsic stability boundary are derived in the third order nonlinear approximation. They are valid for any propellant model and contain the first, second, and third derivatives of the surface temperature and temperature gradient at the propellant surface with respect to the burning rate. Close to the stability boundary two branches of the limit cycles are obtained. The limit cycle frequency at the α -branch is close to the natural frequency of the propellant. At the β -branch, it approximately equals one half of that. The zero mode (DC shift) in both cases is negative and proportional to the square of the first mode amplitude. Numerical results are given for three particular propellant models with different steady-state burning laws.
