Short Communication Transition of Ignition between Laminar Premixed and Nonpremixed Jets

摘要

For boundary-free shear flows, less attention was paid to ignition of jet flows even though the ignition criteria of mixing layers were treated [1, 2]. Similar to cases of mixing layers, the ignition of jets is physically expected to occur in the shear mixing layer. However the minimum streamwise distance (ignition distance) mea- sured from the jet exit to the location where the ignition is achieve is still unsolved.
