The faculty member in the College of Engineering, University of Al-Mustansiriyah, Dr. Ahmed Munir El-Din Faeq conducted a study on the liquid phase dynamics during the combustion of two fuel drops from diesel-based fuel mixtures. The study, which was published in the Journal of Thermology and Practical Fluids in Scopus, reviewed that the liquid phase processes that occur during the combustion of fuel droplets are important in determining the behavior of the overall combustion process, especially with regard to dual fuel droplets. The study demonstrated preparing two types of biofuel (in which diesel is the main fuel), developing a system for rapid imaging and enlarging the size of the captured image to approximately 30 times the real size, and using it to track the combustion of droplets and their internal part at high imaging rates of up to (40000) frames per second, as well as a spatial and temporal tracking of the formed core. The study concluded that all fuels have the same behavior as shown by the combustion of one isolated drop of fuel.
