Adsorption calorimetry in supported catalyst characterization : adsorption structure sensitivity on pt(y-Al2o3
Üner, Murat; Üner, Deniz; Department of Chemical Engineering (2004)
In this study, the structure sensitivity of hydrogen, oxygen and carbon monoxide adsorption was investigated by changing the metal particle size of Pt/Al2O3 catalysts. 2 % Pt/Al2O3 catalysts were prepared by incipient wetness method; the particle size of the catalysts was manipulated by calcining at different temperatures. The dispersion values for the catalysts calcined in air at 683K, 773K and 823K were measured as 0.62, 0.20 and 0.03 respectively. The differential heats of adsorption of hydrogen, carbon ...
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 ...
Design optimization of whiffletree systems for wind turbine blade testing
Yeniceli, Süleyman Cem; Kayran, Altan; Department of Aerospace Engineering (2014)
In this thesis, the design optimization of a whiffletree system, which is used to simulate the loads for a selected design load case by applying discrete test loads on a wind turbine blade, is performed. Firstly, distributed design loads are calculated for the selected load case by using Microsoft (MS) EXCEL. Then, the test load optimization is performed with the Solver Add-In of the MS EXCEL to find the optimum locations of the load saddles which give the best moment distribution along the blade span accor...
Effect of polyglycols on hydrate formation during drilling operations
Tahir, Abbas N; Mehmetoğlu, Mustafa Tanju; Department of Petroleum and Natural Gas Engineering (2005)
The aim of this experimental study is to investigate the inhibitive properties of polyglycol and polyglycol+KCl aqueous solutions on hydrate formation, which causes serious fluid flow problems, especially during deepwater drilling operations. As the petroleum industry continues to search oil in deeper and deeper seas, the possibility of facing hydrate problems during drilling operations increases because of the suitable conditions for hydrate formation. The main goal of this study is to investigate the hydr...
Numerical Improvement of Terahertz Time-Domain Spectroscopic Measurements
Koseoglu, D.; Berberoglu, H.; Altan, Hakan (2009-11-06)
We have developed an algorithm to efficiently eliminate unwanted reflections typically observed in the data obtained by Terahertz time-domain spectroscopic (THz-TDS) methods. The algorithm works by eliminating the reflections from the boundaries. The numerical improvement of the data allows better analysis of the critical parameters obtained by THz-TDS systems.
