How to publish in this journal


The IJTPP has been conceived as an interdisciplinary dissemination tool, although the core of the journal remains the design, the analysis, the modeling and the testing of turbomachinery and turbomachinery based propulsion and power system. Contributions in the important fields of hydro, marine and wind energy producing devices, as well as unconventional fluid/flow applications in turbomachinery, are also welcome. The IJTPP invites submissions on a wide range of disciplines, including to: -turbomachinery- propulsion- power generation- thermodynamics- fluid mechanics- heat transfer- applied combustion (aeronautic/aerospace)- marine and industrial energy devices and systems Join the conversation about this journal

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Total Documents

Evolution of the number of published documents. All types of documents are considered, including citable and non citable documents.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
