Abstract

A novel shear layer control technique used to enhance the mixing of heated jets has been the subject of study in our laboratory (Strykowski et al., 1993; 1996). The technique is based on the self excitation of a countercurrent shear layer which is established by the introduction of a reverse flow around the perimeter of an axisymmetric or rectangular jet. Because of its effectiveness, it is suggested that such an active shear layer control technique may also enhance the combustion processes in jet flames. To evaluate this hypothesis, an ON-LINE PIV system is used to characterize the velocity field, in both the cold reactant flow and the hot post-flame regions, of an excited, premixed jet flame issuing from a modified round nozzle burner.
