Abstract

2D-PIV measurements were performed in a novel non-premixed model GT burner designed to promote intense mixing of the fresh fuel/air with the product gases. The axial and tangential flow field measurements reveal three distinct zones, viz. bluffbody-stabilized, swirl-stabilized and an intermediate zone. The high vorticity fields generated by the converging–diverging flow field will promote intense mixing of the reactants and thereby favour a reduction in the thermal NO\(_{\text {x}}\) emissions. The measurements show the presence of fine-scale turbulent eddies in the intermediate zone. This, along the relatively low extensive strain fields, will aid in the flame stabilization at these locations.
