About Faculty of Science

Faculty of Science

The Faculty of Science is the core at the University of Tripoli, as it was the first that established in this prestigious university. It is also the first faculty of science in Libya. At the present, it includes ten scientific departments: Departments of Zoology, Mathematics, Physics, Chemistry, Botany, Geology, Computer Science and Statistics, Atmospheric science and geophysics. It currently works to create a new department of Archaeology in order to study the scientific and research side of the historical heritage of the Libyan people. Graduates of this college have worked in various governmental sectors, such as oil exploration, extraction and refining, chemical industries complexes in Abu Kamash and Ras Al-Anuf, as well as plastics companies in production and manufacturing, and in factories for soap, cleaning materials and others. They were also recruited by the education sector in different research and pedagogical areas.

 

The graduates of this faculty have led the scientific process for many years and still represent the first building block in all colleges of science, and some other colleges in all Libyan universities for the past five decades. The scope of work for graduates included Faculties of Medicine (in the field of basic sciences, biochemistry, anatomy, histology and microbiology), many departments in the Faculty of Agriculture, general engineering, chemical and geological engineering; in particular, medical technology and pharmacy, and the Faculty of Economics and Arts. The Faculty of Science provides teaching assistants to other faculties and universities in the Libyan state.

 

The Faculty of Science is the first to create graduate studies programs in Libya, despite the nature of graduate studies in basic sciences, which need capabilities other than competent professors. Teaching staff in this institution graduated from international universities in the West and the East (USA, UK, Australia, and other European countries). They graduated from universities that are well-known for their high academic standard.

 

Having obtained their first university degree or higher degrees of specialization from Libya or abroad, graduates of Faculty of Science worked for industrial and nuclear research centers, petroleum sector, marine life, biotechnology, plastics, and other specialized research centers.

 

The Faculty has also enriched the scientific research movement in the fields of basic sciences in the Libyan state through the issuance of refereed basic science journal.

Modeling effects of outlet nozzle geometry on swirling flows in gas turbine

Swirl stabilised combustion is one of the most successful technologies for flame stabilisation in gas turbine combustors. Lean premixed combustion systems allow the reduction of NOx coupled with fair flame stability. The swirl mechanism produces an aerodynamic region known as central recirculation zone (CRZ) providing a low velocity region where the flame speed matches the flow velocity, thus anchoring the flame whilst serving to recycle heat and active chemical species to the root of the former. Another beneficial feature of the CRZ is the enhancement of the mixing in and around this region. However, the mixing and stabilisation processes inside of this zone have shown to be extremely complex. The level of swirl, burner outlet configuration and combustor expansion are very important variables that define the features of the CRZ. The complex fluid dynamics and lean conditions pose a problem for stabilization of the flame. The problem is even more acute when alternative fuels are used for flexible operation. Therefore, in this paper swirling flame dynamics are investigated using computational fluid dynamics (CFD) with commercial software (ANSYS). A new generic swirl burner operated under lean-premixed conditions was modelled. A variety of nozzles were analysed using isothermal case to recognize the the behavers of swirl . The investigation was based on recognising the size and strength of the central recirculation zones. The dimensions and turbulence of the Central Recirculation Zone were measured and correlated to previous experiments. The results show how the strength and size of the recirculation zone are highly influenced by both the shear layer surrounding the Central Recirculation Zones (CRZ) and outlet configurations. arabic 11 English 64

Petrography and Diagenesis of `as Sarir Formation` in Abu Attifel Oil Field, Sirt Basin, Libya

Abstract The Sirt Basin is one of the youngest sedimentary basins in Libya and covers an area of approximately 600.000 km² in north central Libya. It is located on the northern margin of the African plate, with approximate coordinates 14°00`- 20°00`E and 28°00`-31°00`N. The Late Jurassic-Early Cretaceous as Sarir Sandstone in the Sirt Basin evolved as a consequence of the interplay between global eustasy and regional tectonics. As Sarir Sandstone of the eastern Sirt Basin is composed mainly of sandstones and shales resting unconformably on a basement complex of igneous and metamorphic rocks. It is unconformably overlain by the Upper Cretaceous sediments of Maragh, Lidam and Etel formations. It has been subdivided into three members. The upper member consists mainly of sandstones with intercalations of siltstones and shales of variable thickness. The middle member consists of shale and silty shale. The basal part of the formation, which rests directly on the crystalline basement represents the lower member. It is comprised of sandstone with subordinate intercalations of siltstones and shale. Two main facies have been recognized on the basis of lithological features and types of stratifications: which consist mainly of shale and intercalation of silt and sand. The Middle Shale Member consists mainly of shallow lake deposits, containing black shale facies. Continental Fluvial Deposits represent most of the cored interval and it belongs to the Upper as Sarir Sandstone. These facies have been subdivided into braided and meandering lithofacies: The braided depositional system, has been recognized in three different intervals of the studied cores; classified as subfacies (1), subfacies (2) and subfacies (3). The meandering depositional system, represents three sub-environments including point bars, abandoned channels and over-bank deposits. The reservoir characteristics of these sediments are studied on the basis of porosity, permeability and reservoir zonation. The reservoir quality of As Sarir Formation is largely controlled by primary sedimentary features associations, which were shaped by the depositional environments. Meandering Lithofacies are formed from continuous sand successions and show good porosities, up to 18.51%, and permeabilities up to 125.5mD. The Braided Lithofacies also show good reservoir quality, but the effective porosity and permeability are lower, because of associated shales. The most important diagenetic features responsible for a reduction in reservoir quality are those resulting from compaction, cementation, and the diagenesis of clay minerals.
