A TRANSIENT SPRAY MIXING MODEL FOR DIESEL COMBUSTION

A transient spray mixing model forming the basis of heterogeneous combustion in direct injection diesel engines is described. Experimental results of transient fuel sprays in a high pressure, high temperature chamber form the basis of spray growth equations. Progressive evaluation of combustion zones is determined by the fuel-air mixing process. The role of fuel-air mixing in diesel combustion is discussed. The model results are compared with experimental data. /GMRL/
