Determination of the dispersion of supported Pt particles by gas-phase and liquid-phase measurements
Kivrak, Hilal; Mastalir, Agnes; Kiraly, Zoltan; Üner, Deniz (Elsevier BV, 2009-02-15)
The dispersion of a Pt/gamma-Al2O3 catalyst was investigated by various experimental techniques. The values obtained by gas-phase hydrogen and carbon monoxide adsorption and transmission electron microscopy (TEM) were consistent for the metal:adsorbate stoichiometry of 1:1. However, these methods overestimated the number of active sites available for a liquid-phase reaction. For the hydrogenation of styrene in the presence Of CS2 as a catalyst poison, only the defect sites were found to be active in the cat...
Determination of vibroacoustical behavior of plates by intensity methods
İnalpolat, Murat; Çalışkan, Mehmet; Department of Mechanical Engineering (2004)
In this study, sound radiation and power flow characteristics of plates which constitute the bodies of common engineering applications like cars and household appliances are investigated. Three different vibro-acoustical measurement techniques are used in an integrated manner and results obtained are compared with those obtained from analytical models developed. Two-microphone sound intensity measurement with a probe utilizing side-by-side configuration is used to analyze the near-field radiation characteri...
Küçültülmüş Tambur Testi ile Demir Cevheri Peletleri Aşınma Dayanımı Belirlenmesi
Sivrikaya, Osman; Arol, Ali İhsan (null; 2019-04-19)
The tumbling-abrasion indices of iron ore pellets are measured according to instructions in ASTM E279- 97 (2010). This test measures the resistance of the product pellets under certain abrasive condition in a standard test drum. However, this test requires 11.3 kg pellet to carry out a single tumbling-abrasion test. This amount of pellet can be obtained from industrial-scale pellet production. However, it is impossible to produce this amount of pellet in laboratory-scale investigation since the capacities o...

In this paper, wake shapes of wind turbine rotors are investigated by using CFD and analytical wake models. The flow around the NTNU model turbine is simulated using the Reynolds-Averaged Navier-Stokes Equations with Spalart-Allmaras, standard k-epsilon, standard k-omega, and k-omega SST turbulence models, k-kL-omega and Transition SST transition models and also with two different freestream turbulence intensities as low and high values of 0.23% and 10%, respectively. The simulations are done for a single t...
