Large-eddy simulation of n-dodecane spray flame : Effects of nozzle diameters on autoignition at varying ambient temperatures
In the present study, large-eddy simulations (LES) are used to identify the underlying mechanism that governs the ignition phenomena of spray flames from different nozzle diameters when the ambient temperature (T am) varies. Two nozzle sizes of 90μm and 186μm are chosen. They correspond to the nozzle sizes used by Spray A and Spray D, respectively, in the Engine Combustion Network. LES studies of
