Abstract

The blow-out limit for jet flames issuing from an axisymmetric nozzle is increased by an order of magnitude by means of a shear layer control technique. 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. The mechanisms responsible for this remarkable increase of the blow-out limit are characterized by means of Particle Image Velocimetry.
