Sprays and Droplets Dynamics in Fuel Injector Combustion Applications

Combustion helps in ensuring safety and efficient energy utilization and in understanding the mechanics behind pollutant destruction and formation. Combustion dynamics is the area that has recently received fresh emphasis. This is because of advancements in the efficiency of energy, in low emissions combustion system for the aerospace power plant and the ground base. The existence of instability in thermal acoustic commonly referred to as combustion instability has been hindrances in the developing combustors for jet engines, domestic heaters, rockets, and for the power generating gas turbine. It is important to understand how to control combustion instability. In recent times, a reduction of the combustion noise has been prioritized, in an effort to reduce noise pollution emanating from the power plant. The low emission combustors are susceptible to flame blow out, and combustion instability. Faster developments in the area of pulse denotations engine have fuelled research in this area. Pulse combustors are currently applicable to energy in improving energy intensive efficiency processes, taking advantage of the increase in energy transport, mass, and momentum. Liquid fuels are used in combustors. This implies that combustion dynamics, droplet dynamics, spray dynamics and the atomization are closely related. This paper explores the application of spray and droplets dynamics in fuel injector combustion in real life situation, as well as, their application in industrial processes.Sprays are used in many places. They are used to facilitate accurate fuel injection. In this respect, droplet and spray dynamic within a fuel injector have vast applications.
