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: 0.4 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: 0.00005 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: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

Краткое описание

The D.C. plasma spraying process leads to coatings with high-level properties. The control of these properties implies to well overcome the process and in particular the interactions between the particles and plasma plume and between particles and substrate. The plasma jet exhibits high fluctuations outside the torch due to the arc root movements on the anode wall inside the torch. These movements result in a fluctuating plasma jet outside the torch and air engulfment. In this paper, a simple numerical model based on gas heating by JOULE effect in the anode is proposed to reproduce the flow transient behaviour. The predictions of the model (centreline velocities and temperatures of the gas) are compared with experimental values. Also, zirconia particles are injected in the transient simulated flow. Depending on the plasma plume stretching outside the torch and particle size, the particle trajectories, velocities and temperatures present high variations, leading to particle thermocinetic states at impact quite different from one particle to the other.
