Levant Bölgesi’ndeki ticaret sisteminden başlayarak bölgenin hidrokarbon jeopolitiğine geçiş sürecine kadar uzanan tarihsel gelişimin uzun erimli (longue dureé) bakış açısıyla incelendiği bu çalışmada, bölgenin günümüzdeki durumu, petrol ve doğal gazın arama, üretim ve ihracı konusunda özellikle 2000’li yıllardan bu yana yaşanan gelişmelerle değerlendirilmiştir. Bölgenin hidrokarbon jeopolitiğindeki çatışma ve iş birliğinin sabit ve değişen boyutlarına, uluslararası ilişkilerin güç politikaları ...

The Weather Research and Forecasting Model permits finescale large-eddy simulations (LES) to be nested within coarser simulations an approach that can generatemore accurate turbulence statistics and improve other aspects of simulated flows.However errors are introduced into the finer domain fromthe nestingmethodology. Comparing nested domain flat-terrain simulations of the neutral atmospheric boundary layer with singledomain simulations using the same mesh but instead using periodic lateral boundary ...

This article aims to emphasize the importance of lignite which is the mostly used domestic energy source in the Turkish energy mix by briefly overviewing its geology reserves and exploration. Lignites are distributed in mostly continental sedimentary basins of Tertiary age all over the country. The lignite-bearing basins display the characteristics of different geological settings of which grabens and half-grabens are the most common ones especially in western Anatolia. The geological and chemical ...

This article focuses on the mining activities of Turkish Coal Enterprises (TKI) the major lignite supplier in Turkey. First we analyzed the lignite production and overburden removal activities of TKI from a historical perspective and then employed the Principle Component Analysis to build a mining efficiency index of TKI and investigated its historical development since the establishment of the company. We found that labor productivity and operational structure have been the most important factors ...

Results of a high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel with a flat bed at a high Reynolds number (ReD = 160000). The influence of Reynolds number on the development of the mixing layer as well as the vertical non-uniformity in the mixing layer structure is discussed. The numerical results show that as Reynolds number increases the mixing layer grows rapidly but also ...

The dependence on imported energy sources is one of the biggest challenges that Turkey and many other similar countries face in the 21st Century and the gap between production and consumption cannot be decreased without increasing the domestic production. Forecasting of domestic energy production therefore plays a vital role in order to be able to develop sound energy policies towards maintaining sustainable development. However although this question is essential in this respect especially for ...

In this article in general the relationship between international climate change initiatives and energy geopolitics was analyzed and in particular the developments in energy geopolitics were investigated with a historical point of view by dividing the years between 1965 and 2014 into periods of geopolitical intensity and geopolitical stability based on long-term periodic variations in oil prices. More specifically the reasons why international initiatives such as the Kyoto Protocol regarded as an ...

Since the discovery of oil at Kirkuk in northern Iraq oil has shaped relations between Iraq and Turkey as the former needed markets and export routes to the Mediterranean and the latter reliable sources of supply. This article examines the origins of the Kirkuk-Ceyhan oil pipeline from northern Iraq to the Turkish Mediterranean coast charting the period of Iraqi-Turkish economic rapprochement in the 1960s to the construction of the pipeline in the 1970s. It also seeks to add to our collective ...

A high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel over two-dimensional (2D) dunes. The study discusses the vertical non-uniformity in the mixing layer and provides a quantitative characterization of the growth of the large-scale quasi 2D coherent structures with the distance from the splitter plate. The presence of large-scale roughness elements in the form of an array of ...

This article aims at evaluating the historical determinants and implications of Turkey's natural gas import dependency. We implement principle component analysis (PCA) methodology to construct a natural gas import vulnerability index (NGIVI) for the period between 1986 and 2014 using five factors: (1) the share of natural gas in primary energy consumption (2) the share of natural gas in primary energy imports (3) the non-diversification of natural gas import sources (4) the share of LNG in total ...
