Motivation and Objectives
Ignition quality tester (IQT) is a standard device to measure the cetane rating of various fuels. While it is widely used for ignition characterize the ignition property of many practical fuels as industry standard, the existing measurement techniques lack in details about the spray evaporation and dispersion characteristics in order to clearly distinguish the physical and chemical nature of the ignition behavior. CONVERGE is being used with detailed chemical kinetic mechanism to predict the details of the spray dynamics, dispersion, and autoignition characteristics within the IQT. The images show the n-heptane spray development within the IQT at 1ms (left) and 3ms (right) after the injection.
