Experimental research on in-tube condensation under steady-state and transient conditions
Tanrikut, A; Yesin, O (2005-01-01)
In this research study, in-tube condensation in the presence of air was investigated experimentally at a heat exchanger of countercurrent type for different operating conditions. The test matrix for the steady-state condition covers the range of pressures P = 1.8 to 5.5 bars, vapor Reynolds numbers Re, = 45 000 to 94 000, and inlet air mass fraction values Xi = 0 to 52%. The effect of air manifests itself by a reduction in the local heat flux and the local heat transfer coefficient. The local heat transfer ...
DSMC Simulations of low-density choked flows in parallel-plate channels
Ilgaz, M; Çelenligil, Mehmet Cevdet (2002-07-25)
Rarefied choked flows in parallel-plate channels have been studied using the direct simulation Monte Carlo technique. Calculations are performed for various transitional flows, and results are presented for the computed flowfield quantities, wall pressures and discharge coefficients. Comparisons are made with the available experimental data, and the physical and numerical factors which affect the solutions are discussed. Separate calculations are performed for the "nearly-incompressible" rarefied channel fl...
Instability studies in amorphous silicon based alloys
Özdemir, Orhan; Katırcıoğlu, Bayram; Department of Physics (2004)
The pixel element which is an integrated combination of a p-i-n diode with a thin film transistor (TFT) is used to produce image sensor arrays in scanning and displays technologies, necessitating the deposition of hydrogenated silicon based semiconducting and insulating thin films such as a-Si:H, a-SiNx:H over large area. The widely used techniques to achieve this goal is the plasma enhanced chemical vapor deposition (PECVD) due to its large area and low temperature (? 300 ?C) abilities. In particular, PECV...
Harmonic response of large engineering structures with nonlinear modifications
Kalaycıoğlu, Taner; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2011)
During the design and development stages of mechanical structures, after each modification made in order to satisfy design criteria, dynamic characteristics of the structure change and should be determined through reanalyzing the structure dynamically. Due to the significance of computational time and cost in design processes, it is inevitable for structural modification methods, especially for large systems, to become involved in predicting the dynamic behavior of modified structures from those of the orig...
Estimation of the formation temperature from the inlet and outlet mud temperatures while drilling geothermal formations
Tekin, Sema; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2010)
Formation temperature is an important parameter in geothermal drilling since it affects all the components of the system such as drilling fluid, drilling operations and equipment through mud temperatures. The main objective of this study is to estimate the formation temperatures of five geothermal wells in Germencik-Ömerbeyli geothermal field by using inlet and outlet mud temperatures obtained during drilling. For this purpose, GTEMP, a wellbore thermal simulation model is used to simulate the process of dr...
