How to publish in this journal



Progress in Energy and Combustion Science (PECS) publishes review articles on all aspects of energy and combustion science, providing a comprehensive in-depth overview of a particular topic. Occasionally, PECS solicits short Perspectives to highlight recent successes, current developments, and future research needs in energy and combustion science. While PECS spans the broad field of energy science, it focuses particularly on the fields of combustion and fuel science. Combustion has played an important role in the world's energy systems and will continue to do so in years to come. As time passes, technological demands evolve and change. For instance, the challenges we face today include conservation of energy, addressing the problem of global climate change, and environmental concerns, and together these require more efficient and cleaner combustion. Beyond energy, combustion plays an important role in process technology and materials science. PECS publishes reviews on all such topics, including concepts, methodologies, processes, and technology.

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.

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.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
