In the first part of this research, kinetic software was developed for the evaluation of kinetic parameters using nonisothermal thermogravimetry data. Different computational methods were used and applied to a set of experimental and simulated data distributed in the ICTAC (International Confederation for Thermal Analysis and Calorimetry) kinetics project. The reliability of the software was verified by comparing the kinetic results and it was observed that the results were in good agreement. In the second part, developed software was applied to determine the kinetics of a tar sand sample. Therefore, experiments were performed at three different heating rates, in the temperature range of 20-900 degrees C. Different stages of mass loss regions were observed in TG-DTG curves. Ozawa-Flynn-Wall (OFW), Kissinger, and Augis-Bennett kinetic models were used to determine the activation energy of tar sand sample and the results are discussed.

Development of a software for determination of kinetic parameters in thermal analysis
Ertunç, Göker; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2011)
In this thesis, a new software, THERA-Kinetics was developed for the evaluation of kinetic parameters using non-isothermal data. Different computational methods, available in the software, were applied to a set of experimental and simulated data distributed in the ICTAC (International Confederation for Thermal Analysis and Calorimetry) Kinetics Project. The reliability of the software was verified by comparing the kinetic results, which were in good agreement, with those obtained by the participants of the ...
Thermal characterization and model-free kinetics of biodiesel sample
Kök, Mustafa Verşan (2015-11-01)
In this study, combustion and pyrolysis behaviours of methanol route biodiesel were investigated using thermal analysis techniques known as simultaneous thermogravimetry and differential scanning calorimetry (DSC) at different heating rates. Reaction regions, peak temperatures, mass loss and heat flow rates of the biodiesel sample are determined using TG-DTG and DSC data. It was found that as the heating rate of the reactions increased, peak temperatures of the reactions shifted higher temperatures, implyin...
Implementation of turbulence models on 2d hybrid grids using an explicit/implicit multigrid algorithm
Yılmaz, Ali Emre; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2011)
In this thesis study, implementation, numerical stability and convergence rate issues of turbulence modeling are explored. For this purpose, a one equation turbulence model, Spalart-Allmaras, and a two-equation turbulence model, SST k-w, are adapted to an explicit, cell centered, finite volume method based, structured / hybrid multi grid flow solver, SENSE2D, developed at TUBITAK-SAGE. Governing equations for both the flow and the turbulence are solved in a loosely coupled manner, however, each set of equat...
Physics informed neural networks for computational fluid dynamics
Aygün, Atakan; Karakuş, Ali; Maulik, Romit; Department of Mechanical Engineering (2023-1-17)
In this work, we use physics-informed neural networks (PINN) to model the problems generally used in computational fluid dynamics (CFD). Since PINN does not need any discretization scheme or mesh generation, this approach is easier to implement compared to conventional numerical methods. In the context of CFD problems, the effect of network parameters is shown in the convergence and the accuracy of the solution. The solutions to forward problems are chosen with simple geometries since as the nonlinearity in...
Thermal Analysis and Rheological Study of Ocma Type Bentonite Used in Drilling Fluids
Kök, Mustafa Verşan (2013-01-01)
In this research, Ocma type of bentonite sample was studied by x-ray diffraction, Fourier transform spectrophotometer, viscometer, differential scanning calorimeter, and thermogravimetry. It was observed that the major clay mineral was smectite and montmorillonite. Different band intervals were studied by Fourier transform spectrophotometer. The weight loss regions related to the dehydration and de-hydroxylation process were determined by differential scanning calorimeter and thermogravimetry at different h...
