An experimental investigation has been carried out to determine the fresh mixture entrainment in the circulation zone of a jet curtain stabilized flame. The entrainment values were obtained indirectly by determining the fuel-air ratios at lean blow-off limits of the flame.13; These experiments were carried out in a rectangular duct, of cross section 203.2mm x 152.4mm, at a pressure of 9x10 to the 4th N/sq m. Jets from the flameholder were injected perpendicular to the mainflow which consisted of a premixed mixture of aviation kerosene and air. Similar tests were also carried out on a 30 deg V-gutter which13; produced a geometric blockage of 0.375. The results obtained indicate that the entrainment fraction of the jet curtain flameholder is about 0.20 while that of the V-gutter, of comparable blockage, is only about 0.04.
