Study on ignition and combustion of gas jet and liquid spray fuels

... various gasjet and liquid- spray fuels under simulated diesel combustion conditions, in terms of:  Jets and sprays penetration and dispersion with time  Vapor phase penetration and mixture formation... results: ignition delay definition for gaseous fuel and ignition delay definition for liquid fuels 2.3.1 Ignition delay for gaseous fuel jets The definition of ignition delay these gaseous fuels. .. ignition was reported to be negligible [2], [10] 2.3 Determination of ignition delay Both liquid and gaseous fuels were fundamentally studied ignition and combustion Two definitions of ignition
