The Journal of Engineering Research is a peer-reviewed scientific journal issued by the Faculty of Engineering, University of Tripoli - Libya. This journal aims to spread innovative knowledge in the field of engineering sciences and technology. It is an open access online journal that is issued twice a year. A special issue of the journal can be issued if the editorial board deems a need for that. All published research papers are subject to the principles of scientific evaluation in the field of publication and documentation.
The journal's activity began with the end of the eighties of the last century, where the first issue was published in March 1989, the second issue was in December 1991, the third issue was in March 1992, and the fourth issue was issued in June 1995. After that, the journal stopped being issued.
The journal has been re-issued continuously since 2006, with two issues per year (March and September), where it issued thirty-one issues until the end of March 2021 on the internet.
The editorial board seeks to develop it, expand its reach and provide an opportunity for those interested to view it, as all its issues have been uploaded to the journals website on the internet.
The journal vision
Achieving primacy and excellence in the field of publishing scientific engineering research in both Arabic and English, and regional and global spread in the field of scientific publishing.
The journal message
Contribute to the production of knowledge that serves society, and support creativity in the field of engineering sciences by publishing innovative and refereed scientific research.
The journal objectives
- Publishing solid and distinguished scientific research in the field of engineering sciences, which contributes to the progress and development of society.
- That the journal be the first choice for publishing engineering research, and that it be among the prestigious scientific journals, highly rated in the field of engineering sciences.
. Reversal Flow was observed near the axis for aiding buoyancy flow. Streamlines in the channel, isotherms, temperature distribution, and velocity profiles, local Nusselt number and friction factor were presented. The numerical results presented revealed some interesting features which may be summarized as: (i) the effects of the heated part of the channel on the hydrodynamic and thermal fields are demonstrated for│Gr │≥ 105 for aiding flow. (ii) Nusselt number approaches the asymptotic value at the vicinity of the channel wall for Gr ≤ 105. For Gr ≥ 106 the Boussinesq approximation over predicts the overall heat transfer rate. (iii) For Gr up to 4x105 The Boussinesq approximation still predicts reasonably the heat transfer rate. In general, the heated section modifies the flow field and hence the wall convective heat transfer.
