Thermal Modeling and Verification of PV Module Temperature and Energy Yield Using Outdoor Measurements for Ankara, Turkey
Tuncel, Bilge; Akınoğlu, Bülent Gültekin; ÖZDEN, TALAT; Balog, Robert S (2018-11-14)
Ankara is in the Central Anatolia region of Turkey where the climate is dry-continental with an annual solar insolation of around 1750 kWh/m(2). In the transition to renewable energy, detailed analyses are required to ensure effective and economic utilization of the available solar resource. An essential part of these analyses is to calculate expected energy yield. For photovoltaic (PV) systems, this includes the effect of temperature on the PV efficiency, which determines the power yield of the PV modules....
Limestone decay in historic monuments and consolidation with nanodispersive calcium hydroxide solutions
Caner, Evin; Saltık, Emine Nevin; Restoration in Department of Architecture (2011)
Exposure to atmospheric conditions results of deterioration in historic monuments. and their stones. Limestone conservation presents many problems that have to be investigated in detail. In this study, limestone deterioration and development of its conservation treatments were investigated through examination of the statues carved from karstic limestones in Nemrut Dağ Monument. The decay mechanisms that had major roles in their deterioration during two thousand years of exposure to atmospheric conditions an...
Managed pressure drilling techniques, equipment & applications
Tercan, Erdem; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2010)
In the most of the drilling operations it is obvious that a considerable amount of money is spent for drilling related problems; including stuck pipe, lost circulation, and excessive mud cost. In order to decrease the percentage of non-productive time (NPT) caused by these kind of problems, the aim is to control annular frictional pressure losses especially in the fields where pore pressure and fracture pressure gradient is too close which is called narrow drilling window. If we can solve these problems, th...

Solar generated steam injection in heavy oil reservoirs
Afşar, Cansu; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2014)
Turkey is one of the countries having mostly heavy oil reservoirs with 10-15˚ API gravity. Due to high amount of residual oil in the reservoir, thermal injection methods are evaluated to increase recovery in south-east of Turkey. However, the fuel cost of steam generation, that represents 60% of the total project cost, is a major challenge for companies. Combination of solar generated steam technology and heavy oil recovery techniques encourage companies to reduce the operation costs. This solar aided steam...
