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...
Smart water displacement an alternative enhanced oil recovery technique
Polat, Can; Parlaktuna, Mahmut; Saner, Salih; Department of Petroleum and Natural Gas Engineering (2015)
The aim of this study is to investigate the effect of smart water displacement on oil recovery. The brine samples were prepared considering the characteristics of the samples proved to be effective in oil recovery. The effect of these brine samples on rock wettability was observed using Modified Flotation Test (MFT) procedure. The effect of changing brine salinity on interfacial tension between brine and oil samples was observed using interfacial tension meter and ring tensiometer. Liquids used in spontaneo...
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...
Random walk particle modelling of polymer injection using matlab reservoir simulation toolbox
Mamak, Gökhan; Durgut, İsmail; Department of Petroleum and Natural Gas Engineering (2017)
Enhanced oil recovery (EOR) is essential to increase the maximum recoverable oil by natural means of production. Having chosen an EOR method, the effectiveness of the method should be analyzed before applying to a reservoir since the methods are generally costly. Polymer injection is a chemical EOR process, where the injected polymer with water increases the water viscosity, and help increasing the sweep efficiency in the reservoir. In order to model the effects of polymer injection, the random-walk particl...
