“…The features of ANSYS Forte make it more convenient and effective in manipulating the advanced fuel spray models and their chemical kinetics through ANSYS Chemkin pro solver. With less attention, Open FOAM has been used to simulate n-heptane combustion by analyzing a 40 wedge sector of cylindrical domain in a constant volume combustion chamber [82].…”

“…Different turbulence modeling and chemical kinetic skeletal mechanisms were adopted and developed for combustion simulation. The two-equation k − ε and its developed form, Renormalization Group (RNG) models are the most widely selected turbulent models for simulating combustion in the IQT [73], [74], [76], [77], [82]. All codes use the Lagrangian-Eulerian approach to determine fluid properties, wherein the liquid fuel spray droplets are tracked through a Lagrangian formulation while the carrier field (hot gases in the chamber) is expressed in an Eulerian formulation and the fluid flow is governed by Navier-Stokes equations [83].…”

The constant volume combustion apparatus, known as the Ignition Quality Tester (IQT T M), is increasingly used around the world to measure the ignition delay (ID) of compression ignited fuels, and to calculate the derived cetane number (DCN) from correlations developed with the cetane number (CN). The IQT is widely used in research due to its capability to manipulate combustion controller parameters, including pressure, temperature, oxygen content and mass of injected fuel. Recently, the IQT has also been used to conduct experiments on fuels with a longer ID, such as gasoline. Most findings from I would like to greatly thank all people who either contributed to the work described with this thesis or to me personally during the working time on it. First and foremost, I would like to express my gratitude and appreciation to my supervisor professor Edgar A. Matida. His continuous support and guidance have demolished the difficulties toward gaining my PhD. I would like to acknowledge the Advanced Engine Technology (AET) Ltd. for allowing me to use their facilities and dedicating an IQT to do my research. The AET staff was wonderful and generous in providing everything for my research. I must thank Mr. Gary Webster, the principal of the AET for the opportunity to work in his laboratory, may he rest in peace. I also want to appreciate the unlimited technical support during experimental work from Luc Menard, Omar Ramadan, Dave Gardiner, and Aaron Wilcox. Without a scholarship from my home country Iraq, it was impossible to achieve this work. I hope all progress and prosperity to my country and peace to all people there. Many thanks to all friends for their emotional supports and invaluable advises. Their encouragement during difficult times of my study has inspired me and made me more productive. Finally, I dedicate this thesis to my family; my beloved mother and father whose love continues as long as my heart is beating, my lovely wife for always standing by me and my kids, my elder brothers Assim and Yasir with respect, and to all other brothers and sisters.
