Summary:

Developing advanced compression ignition and low-temperature combustion engines depends increasingly on chemical kinetic ignition models, but rigorous experimental validation of the models has been limited. Shock tubes and rapid compression machines are often limited to premixed gas-phase studies, precluding the use of realistic, low volatility diesel or biodiesel surrogates. The Ignition Quality Tester (IQT) constant-volume spray combustion system measures ignition delay of low-volatility fuels and could validate ignition models experimentally, but a better understanding of the IQT's processes is needed. KIVA-3V was used to develop a 3D CFD model that accurately reproduces ignition behavior and resolves temperature and equivalence ratio regions inside the IQT. The model's fuel spray characteristics (e.g., velocity) are experimentally validated, and it provides insight, vital to expanding the fuel research capabilities of the IQT, into the complex interaction between fuel spray and combustion processes.
