Thermodynamic study on the magnetic transition and structural phase transition in [(CH3)(2)NH2][Na0.5Fe0.5(HCOO)(3)] by using the Landau phenomenological model
Yurtseven, Hasan Hamit (AIP Publishing, 2020-11-01)
In this study, we apply the Landau phenomenological model to describe magnetic transition and structural phase transition in a metal formate framework (MOF) of the ferromagnetic [(CH3)(2)NH2][Na0:5Fe0:5(HCOO)(3)], namely, DMNaFe. By using the observed data from the literature for the magnetization, the excess heat capacity (Delta CP), and the dielectric constant (e), we predict some thermodynamic quantities as a function of temperature close to the magnetic transition (T-M 1/4 8:5K) and structural (T-c 1/4 ...
Thermodynamic and structural design and analysis of a novel turbo rotary engine
Ercan, Taylan; Akmandor, İbrahim Sinan; Department of Aerospace Engineering (2005)
A novel turbo rotary engine, operating according to a novel thermodynamic cycle, having an efficient compression phase, a limited temperature combustion phase followed by a long power extraction phase is designed. Thermodynamic and structural design and analysis of this novel engine is carried out and two prototypes are manufactured according to these analysis. High performance figures such as torque, power and low specific fuel consumption are calculated. Also the component tests of the manufactured protot...
Thermodynamical parasitic forces in high precision accelerometers on board of a drag-free satellite
Karslıoğlu, Mahmut Onur (Elsevier BV, 2004-03-15)
High-resolution accelerometers and gradiometers on board of drag-free satellites are employed in different scientific space missions. The applications range from experiences in fundamental physics to the earth's observations associated with the precise orbit determination of low earth's orbiter (LEO) particularly in context with the autonomous navigation and the determination of the short wavelength part of the earth's gravity field which is an important topic of satellite Geodesy. A satellite flying drag-f...

Thermodynamics of oxides with substitutional disorder A microscopicmodel and evaluation of important energy contributions
Ceder, Gerbrand; Kohan, Adrian; Aydınol, Mehmet Kadri; Tepesch, Patrick; Vanderven, Anton (1998-03-01)
The first‐principles calculation of finite‐temperature phase stability and thermodynamic properties of multicomponent oxides presents a significant challenge. The time scale on which substitutional disorder occurs prevents the use of standard simulation methods, and a correct description of entropic effects requires that excitation energies can be calculated accurately on the scale of kBT. A model is presented in which substitutional disorder is parameterized with a cluster expansion. The thermodynamics of ...
