Abstrakt

The continuity, momentum, stagnation enthalpy, and species conservation equations for a hot, laminar, round, inert, gaseous jet, entraining a fuel-air mixture from surroundings were solved and the velocity, temperature, and concentration profiles obtained. Above a certain initial jet temperature, the gradients of temperatures in both flow and radial directions became positive at finite distances from the nozzle, and the isotherms bunched together to form the initial stages of a flame front. Correlation with experimental data on propane and ethane showed that this method is suitable for the prediction of jet ignition.
