SPECTROSCOPIC MODIFICATIONS OF PIPPARD RELATIONS AND THEIR APPLICATION TO NH4CL
Yurtseven, Hasan Hamit (1994-07-01)
The Pippard relations have been reformulated in terms of the spectroscopic parameters and applied to the NH4Cl system in the vicinity of its lambda-transition. We have effectively tested some of these relations in an earlier study where we have used, for the frequency shift, data for the nu5 lattice mode of NH4Cl. Here, using our observed frequency shifts for the internal mode, nu2 of NH4+, we have obtained a good fit to the Pippard relations for temperatures below T(lambda) for the NH4Cl system. We have th...

Performance of rectangular fins on a vertical base in free convection heat transfer
Yazıcıoğlu, Burak; Yüncü, Hafit; Department of Mechanical Engineering (2005)
The steady-state natural convection heat transfer from vertical rectangular fins extending perpendicularly from vertical rectangular base was investigated experimentally. The effects of geometric parameters and base-to-ambient temperature difference on the heat transfer performance of fin arrays were observed and the optimum fin separation values were determined. Two similar experimental set-ups were employed during experiments in order to take measurements from 30 different fin configurations having fin le...
Numerical simulation of thermal convection under the influence of a magnetic field by using solenoidal bases
Yarımpabuç, Durmuş; Tarman, Işık Hakan; Department of Engineering Sciences (2011)
The effect of an imposed magnetic field on the thermal convection between rigid plates heated from below under the influence of gravity is numerically simulated in a computational domain with periodic horizontal extent. The numerical technique is based on solenoidal basis functions satisfying the boundary conditions for both velocity and induced magnetic field. The expansion bases for the thermal field are also constructed to satisfy the boundary conditions. The governing partial differential equations are ...
Thickness-dependent nonlinear absorption behaviors in polycrystalline ZnSe thin films
Karatay, Ahmet; Yaglioglu, H. Gul; Elmali, Ayhan; Parlak, Mehmet; KARAAĞAÇ, Hakan (2012-03-15)
Polycrystalline ZnSe thin films have been deposited with different thicknesses by using sputtering evaporation method. Their nonlinear absorption behaviors were investigated by open aperture Z-scan and pump-probe techniques. Linear absorption measurements show redshift in energy as the film thickness increases. This can be attributed to Urbach tail effect. All films exhibit nonlinear absorption for 65 ps pulse duration at lower input intensities while they exhibit saturable absorption at higher input intens...
