Thermal analysis and rheology



Thermal analysis and rheology
Kök, Mustafa Verşan (2008-01-01)
This chapter describes the way in which thermal analysis techniques can play a key role in examining the rheological behavior of crude oils. Crude oil is a mixture of paraffin, naphthenes and aromatic hydrocarbons, and small quantities of oxygen-, sulfur-, and nitrogen-containing compounds and ashing solids. The majority of crude oils and crude oil products contain substantial amounts of petroleum wax. Reservoir crude oils are very close to thermodynamic equilibrium, but during production, changes of temper...

Thermal analysis and kinetics of biomass samples
Kök, Mustafa Verşan (2013-02-01)
In this research, combustion behavior of agricultural residues known as miscanthus, poplar wood, and rice husk was investigated using thermal analysis techniques. Differential scanning calorimeter (DSC) and thermogravimetry (TG-DTG) techniques were used. Combustion experiments were performed at five different heating rates (5, 10, 15, 25, and 50 degrees C/min). The reaction regions, ignition and burnout temperatures, heat flow rate values of biomass samples are determined. Activation energy of the biomass s...
Thermal analysis of power cables
Güven, Oytun; Ertaş, Arif; Department of Electrical and Electronics Engineering (2007)
This thesis investigates temperature distribution and hence heat dissipation of buried power cables. Heat dissipation analysis of a simple practical application and the parameters that affect the heat dissipation are discussed. In analyzing temperature distribution in the surrounding medium , a computer program is developed which is based on gauss-seidel iteration technique. This method is applied to a sample test system and heat dissipation curves for several parameters are obtained. Also, current carrying...
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...
