Thermal analysis of electroinitiated and radiation induced poly(epoxycyclopentanes) and poly(epoxycyclohexanes) by mass spectrometry
Hacaloğlu, Jale; Önal, Ahmet Muhtar (1995-01-01)
Thermal behaviour of electroinitiated and radiation induced poly(epoxycyclopentanes), PECP, and poly(epoxycyclohexanes), PECH, have been studied by a direct pyrolysis mass spectrometry technique. The mechanism of thermal degradation of the samples prepared by electroinitiation was found to be a radical depolymerization mechanism yielding mainly monomer. The broader temperature ranges of thermal decomposition in the case of polymer samples prepared by irradiation may be attributed to more complicated degrada...
Thermal analysis of switched reluctance motor with direct in-winding cooling system
Rahman, Nasim Arbab; Bostancı, Emine; Fahimi, Babak (2017-01-12)
Demand for compact high torque/power density electric machines necessitates the choice of an effective cooling system. The focus of this paper is to compare the steady-state thermal analysis of a naturally air-cooled conventional 8/6 SRM to the same motor with direct in-winding cooling system. The goal is to determine how much torque increase can be achieved by using direct cooling in the windings slots. The results show that the direct cooling of the winding guarantees lower temperature in the windings by ...
Thermal analysis of stirling cycle regenerators
Özbay, Sercan; Tarı, İlker; Department of Mechanical Engineering (2011)
Stirling cycle cryocoolers are used widely in military applications. The regenerator is the key element of Stirling cycle cryocoolers. It is known that performance of the regenerator directly affects the cryocooler performance. Therefore, any improvement on the regenerator will lead to a more efficient cryocooler. Thus, it is essential to have an idea about regenerator parameters and their effects on the system. In this study Stirling engine regenerator, which is constructed by wire mesh screens, is accepte...
Thermal characterization of different origin class-G cements
Kök, Mustafa Verşan (2014-02-01)
In this study, thermal characteristics and kinetics of three different origin class-G cements (Mix, Bolu, and Nuh) were studied using thermogravimetry (TG/DTG) and differential scanning calorimeter (DSC). In DSC curves at different heating rates a number of peaks were observed consistently in different temperature intervals. TG/DTG is used to identify the detected phases and the corresponding mass loss. In the dehydration kinetic study of the different origin class-G cement samples, three different methods ...
