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 temperature and pressure causes a disturbance of the equilibrium and phase separations, such as liberations of gas and precipitation of asphaltene and wax, may result. The goals of treatment of high-pour crude oils with a polymeric pour-point depressant chemical are to reduce the temperature of congealing, to inhibit waxes from precipitating out of solution, to reduce the yield strength of congealed crude oil, and to decrease the viscosity.

Thermal analysis of gray cast iron by interpretation of cooling curves Çetin, Arda; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2002) The aim of the present work is to investigate the relations between data obtained from the cooling curve and its first and second derivatives and the as-cast microstructure of gray cast iron, assuming that the cooling curve reflects the complete history of the solidification process. Fourteen different alloy compositions are prepared in order to obtain statistical predictive models to relate cooling curve parameters with the solidification variables such as chemical analysis, inoculation, graphite shape, pr...
Calorific value determination of coals by DTA and ASTM methods. Comparative study Kök, Mustafa Verşan (2001-08-20) This research comprises the applicability of complex thermal analysis technique (TG/DTG, DTA) in the determination of calorific values of coals of different origin. The calorific values, those obtained by thermal analysis are compared with an adiabatic bomb calorimeter by the standard ASTM method, and the results are discussed.
Thermal behavior and kinetics of crude oils at low heating rates by differential scanning calorimeter Kök, Mustafa Verşan (2012-04-01) The objective of this research was to investigate thermal behavior and kinetics of different origin crude oils in limestone matrix by differential scanning calorimeter (DSC) at low heating rates. In DSC experiments, three distinct reaction regions were identified in all of the crude oil + limestone mixtures known as low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO) respectively. Kinetic analysis of the crude oil samples was determined by different models known as AST...
Wetting behavior and reaction layer formation in C/SiC composite-titanium alloy joints Saltik, Simge; ESEN, ZİYA; Dericioğlu, Arcan Fehmi (2021-09-01) The present study investigates the effect of brazing parameters on reaction layer formation, and mechanical properties of C/SiC composite-Ti6Al4V alloy joints produced by brazing technique. The wetting mechanism of the C/SiC composite surface by the Ag-Cu-Ti-based active brazing filler alloy has also been studied and correlated with the reaction layer formation.
Numerical simulation of turbine internal cooling and conjugate heat transfer problems with Rans based turbulance models Görgülü, İlhan; Akmandor, İbrahim Sinan; Department of Aerospace Engineering (2012) The present study considers the numerical simulation of the different flow characteristics involved in the conjugate heat transfer analysis of an internally cooled gas turbine blade. Conjugate simulations require full coupling of convective heat transfer in fluid regions to the heat diffusion in solid regions. Therefore, accurate prediction of heat transfer quantities on both external and internal surfaces has the uppermost importance and highly connected with the performance of the employed turbulence mode...
