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

ABSTRAKT

The behaviour of plasma jets generated by gas and gas-water torches is different. The difference arises from plasma torch arrangements and from a way of arc stabilization. In the gas torch an arc is ignited between a tip of a cathode and an anode operating as a nozzle and plasma gas is supplied around the cathode. The hybrid gas-water torch combines two types of stabilization: by water vortex and by gas flow. The arc is generated from the cathode and passes through the channel inside the water vortex towards the external rotating anode resulting in a long arc with high voltage. The generated plasma exhibits high values of enthalpy and temperature and low values of density. Thus, the density ratio between plasma and surrounding is much lower than in the gas torch, causing stronger entrainment of the cold ambient air. Moreover, the main plasma flow interacts intensively with an anodic jet, which is formed at the position of the anode attachment. As a result, additional perturbations and deflection of the main plasma flow from the torch chamber axis occur. The mentioned factors affect transfer mechanisms in the gas-water jets. The work considers behaviour of the jets generated by both torches.
