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

SINOPSIS

An investigation of the performance of Ryerson University's prototype laboratory-scale hybrid rocket engine is undertaken in the present study. The evaluation is primarily based on two experimental firings of this engine−one employing low-density polyethylene as the solid fuel and the other employing paraffin wax. Gaseous oxygen is the oxidizer in both cases. The principal test data collected are the firing's head-end pressure/time and thrust/time profiles. A cutaway view of the respective fuel grain at the end of the firing is also an important piece of experimental information. A quasi-steady internal ballistic simulation program is used to compare the predicted numerical results with the experimental test data in order to develop a better understanding of the engine's performance behavior. Factors such as fuel surface roughness, fuel decomposition temperature under non-combustive ablation (when beyond the nominal stoichiometric length limit), and burning fuel surface temperature are among the performance elements of interest that are incorporated into the simulation model and evaluated for their respective influence on the engine's performance. To some degree, the comparisons between the experimental and numerically predicted results indicate some qualitative agreement but less so in other respects. The main differences can likely be attributed to the following undesirable experimental factors: a non-constant, subsonic oxidizer delivery; an overly intense and prolonged ignition process (using steel wool positioned at the head end); and in the case of the paraffin engine firing, an inordinate propensity for the soft paraffin wax to be ejected uncombusted from the combustion chamber.
