Decision of the Society of Thermal Engineers of Serbia, founder of the journal Thermal Science
The Management Board of the SOCIETY OF THERMAL ENGINEERS OF SERBIA, on the session held on March 6th 2013, wishing to create stable financial conditions for publishing the THERMAL SCIENCE journal, reached the following decisions:
Management Board of the SOCIETY OF THERMAL ENGINEERS OF SERBIA and National Editorial Board are aware that this is not popular and easy decision.
In the past 17 years, due to the quality of the papers published, THERMAL SCIENCE journal became a respectable international scientific journal, with continuously growing Impact factor, starting from 0.407 in 2009 up to 0.779 in 2011. Presently, current Impact factor is 1.18.
Number of papers submitted for publication in 2012 was more then 600. From this number, about 500 have been sent for review to the most respectable experts all over the world. National Editorial Board, in order to cope with the everyday growing number of papers submitted and accepted for publication, increased number of papers published in one issue from 10-15 papers in 2008, up to 25-29 in 2012, and increased number of issues per year: in 2005 – 3 issues, from 2006 to 2011 – 4 issues and in 2012 – 5 issues. Last three years we have also published 2 Supplement issues per year.
In spite of these efforts, we have on our waiting list (Online first list) more than 120 papers, and waiting period increased to even 1 and a half year. Also, in order to increase dissemination of the scientific results published in THERMAL SCIENCE, we have increased number of libraries all over the world to which we are sending our journal as hard copy, i.e. printed on the paper. This action has also increased our mailing costs.
As a consequence of the growing number of papers, increased number of issues per year and increased number of pages per issue, and at the same time due to world economy crisis and increase of prices of material and labour, costs of publishing journal, per issue and per page, increased several times.
Being aware that it is not possible to create sustainable financial and editing conditions for publishing the THERMAL SCIENCE journal, due to the fact that subscription cannot provide enough funds, especially considering the increase in number of papers to about 150 papers per year (by decreasing maximum number of pages per paper from 16 to 12), and despite financial help from several sponsors, but at the same time wishing to satisfy interest of the scientists all over the world to publish results of their investigations, the Management Board was forced to accept the above mentioned decision.
This decision will also make possible to fulfil one of the main principles of the National Editorial Board of the journal THERMAL SCIENCE - to publish Open access journal, available to all to publish and read.
THERMAL SCIENCE WILL STAY, AS IT IS NOW, AN OPEN ACCESS JOURNAL.
Editorial Board of the journal Thermal Science paid continual attention to the research of the thermal processes in internal combustion engines, since, motor vehicles of different kind and purposes, and transportation in general, have greatest share in overall fossil fuel consumption and environmental pollution.
This is already a fifth of the journal Thermal Science, dedicated to the recent research of the processes in internal combustion engines. Unfortunately, due to the large number of papers submitted and accepted for publication, we have been forced to move this IC issue, from regular forth issue in 2012, to the first issue, No. 1, in 2013. Guest editor, Prof. Stojan Petrović succeeded, by appropriate choice of the papers, to move emphases of this set of papers, from testing different biofuel blends to fundamental research of the flow, fuel injection, combustion and thermal processes in combustion chambers. I am sure that such choice will be more interesting for researchers and designers and for readers in general.
This is, also, in line with the general policy of the journal Thermal Science, to support, in all fields of the research of thermal processes, those papers which present scientific results contributing to the general efforts of the science - to increase energy efficiency, to decrease of energy consumption in general (and decrease of the fossil fuel consumption, in particular), and to approach whole human activities to the sustainability.
We believe that such publishing policy of the journal Thermal Science is the main reason of constant increase of the journals' Impact factor. Presently, unofficial value of our Impact factor is 1.2. We believe that official value in June 2013 will be also so high.
This issue is again dedicated to the research in the field of procedures and consequences of thermal processes of internal combustion engines. As in the previous special issue of this journal devoted to IC engines, also this time, according to the opinions of our reviewers we have chosen 25 papers from a large number (about 80) of submitted manuscripts on internal combustion engine problems. Unfortunately, a couple of accepted papers could not get into this issue, but it had to be left for a later release. Too, a number of papers have not been accepted for publication not because of their lack of scientific level, but because we wanted to cover as many as possible areas of research on engine problems and not to repeat similar subjects or papers.
Presented papers in this issue suggest that, despite the global crisis in the field of manufacturing industries and vehicle production, research in the area of internal combustion engines are still very actual and intense. Of course, the current world energetic situation, global warming and air pollution give the main boost for this research. The current research trends in the field of internal combustion engines continue to be the improvement of thermal efficiency of engine processes and the achievement of a lower emission of toxic components. Therefore these problems are also represented in the papers of this issue.
The papers in this issue range from fundamental experimental research of real engines parameters up to the theoretical analysis of the thermodynamic cycles (primarily using modern methods of finite time thermodynamics) with the aim to study and optimize their parameters. Between these two extremes are, on the one side, experimental studies of engine flow processes, injection system behaviors and the effects of different interventions on exhaust emissions, and, on the other hand, computational methods of engine process simulation using CFD and phenomenological models. A section of this issue is also devoted to modern methods of prediction and optimization of engine parameters using artificial neural networks and other similar methods, while the second part is devoted to the utilization of various alternative fuels. In addition, special emphasis is given to the application of biofuels with the trend of inedible oil use. This is in line with the intentions of the EU that, from specified mandatory 10% biofuels in engine fuels in 2020, a maximum of 5% can be from the edible oil, which should prevent the conversion of land for food production in polygons to create engine fuel. In any case, the problems of energy efficiency and engine emissions dominate this issue.
Finally, I would like to express my gratitude to all the authors (originating from all around the world) on their desire and interest to publish their research results in our journal. Owing to them the quality of our magazine is growing, which is reflected in a steady increase in its SCI factor. Also, in my own name and on behalf of all authors, I have to pay special appreciation to the reviewers (from eminent international institutions) for their cordial and serious qualitative comments and opinions, which strongly improve the level of this issue, but also essentially help authors to improve the quality of their papers.
