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

SINOPSIS

Synthetic jets are used in several fields because of their simplicity and efficiency, such as active cooling to improve thermal management and active control of the boundary layer separation in various application practices, in order to enhance aerodynamic performance. These devices are generated by a piezoelectric diaphragm embedded in a cavity, through an orifice, in a periodic manner. Also, they have the benefit of being compact with zero net mass flux. To study the synthetic jets experimentally, many practical devices can be used, such as artificial excitation, micro valves, pneumatic, etc. Analytically, several approaches were previously used, such as the theory of plate deformation, a lumped element model based on electroacoustic theory, periodic inlet velocity profiles, etc. In the present study, a numerical approach based on a moving mesh method is proposed in the modeling field as a new approach. The mesh deformation is an important approach component for solving problems with moving boundaries or deformable bodies. The motion might be imposed or an implicit part of a coupled fluid-structure simulation. The new model was compared to theory of plates deformation approach, which has previously been used, and both are validated by the experimental data (given in a NASA workshop on Synthetic Jets Validation CFDVAL2004) to evaluate the performed one. Results show that the flow behavior is reproduced correctly by the new approach.
