• 論文の詳細を見る

• Experimental observations and numerical simulations are conducted on combustion processes of n-decane polydisperse spray entering a gaseous flat flame stabilized in a laminar 2D counterflow configuration. For the gaseous phase, Eulerian mass, momentum, energy, and species conservation equations are solved. For the disperse phase, all individual droplets are tracked without using a droplet parcel model. The experimental results show that blue flames and luminous flames are observed and there are unsteady changes in the behavior. The numerical results show that the spray flame structures vary depending on the supplied quantities of liquid fuel spray. Furthermore, the instantaneous flame structures are consistent with the typical flame structures observed with the experiment.
