In this study; reliability and performance of turbulence models used in CFD softwares to determine the aerodynamics of passenger cars, are tested and compared. In the analyses, drag forces acting on the car, pressure and velocity distributions and wake flow patterns are determined by using several turbulence models with a commercial software Fluent. Calculated results compared to the experimental results given in the literature. It is observed that, turbulence models give relatively reliable results for determining aerodynamic properties of the model car. Among the turbulence models, RNG k-ε and standard k-ω models stand one step ahead of the other models according to results.

CO2 emissions of Turkish manufacturing industry: A decomposition analysis Akbostancı Özkazanç, Elif; Tunç, Gül İpek (2011-06-01) In this study. CO2 emissions of Turkish manufacturing industry are calculated by using the fuel consumption data at ISIC revision 2, four digit level. Study covers 57 industries, for the 1995-2001 period. Log Mean Divisia Index (LMDI) method is used to decompose the changes in the CO2 emissions of manufacturing industry into five components: changes in activity, activity structure, sectoral energy intensity, sectoral energy mix and emission factors. Mainly, it is found that changes in total industrial activ...
Thermoluminescent properties of Sr2P2O7 doped with copper and some rare earth elements YAZICI, AHMET NECMEDDİN; Seyyidoglu, Semih; Toktamis, Hueseyin; Yılmaz, Ayşen (2010-10-01) In this study. Sr2P2O7 was doped with some rare earth oxides (Pr6O11, Nd2O3, Dy2O3, Ho2O3, Er2O3, and Tm2O3) at 0.5%, 1%, 2%, 3%, 4%, 5%, 10%, and 15% (by weight) and co-doped with CuO by heating at 900 C for 10 h. Structural analysis of the products was carried out by powder X-ray diffraction (XRD). XRD patterns of the samples showed that doping did not alter the orthorhombic structure of the Sr2P2O7. Thermoluminescence (TL) glow curve measurements were obtained and these showed that Pr and Cu-doped Sr2P2O...
Physical and optical properties of DCJTB dye for OLED display applications: Experimental and theoretical investigation KURBAN, MUSTAFA; GÜNDÜZ, BAYRAM (2017-06-05) In this study, 4-(dicyanomethylene)-2-tert-butyl-6-(1,1,7,7-tetramethyljulolidin-4-yl-vinyl)-4H-pyran (DCJTB) was achieved using the experimental and theoretical studies. The electronic, optical and spectroscopic properties of DCJTB molecule were first investigated by performing experimental both solution and thin film techniques and then theoretical calculations. Theoretical results showed that one intense.electronic transition is 505.26 nm a quite reasonable and agreement with the measured experimental da...
Gas production from hydrate resevoirs Alp, Doruk; Parlaktuma, Mahmut; Department of Petroleum and Natural Gas Engineering (2005) In this study; gas production by depressurization method from a hydrate reservoir containing free gas zone below the hydrate zone is numerically modeled through 3 dimensional, 3 phase, non-isothermal reservoir simulation. The endothermic nature of hydrate decomposition requires modeling to be non-isothermal; hence energy balance equations must be employed in the simulation process. TOUGH-Fx, the successor of the well known multipurpose reservoir simulator TOUGH2 (Pruess [24]) and its very first module TOUGH...
