The experiments were performed at mainstream mass flowrates of 84 to 146 kg/m**2-sec. The blowing rates were 0. 2, 0. 5 and 0. 9. The injectant gas was swirled by inserts, the helical fins of which made angles of 58 degree or 74 degree with the axial direction. Nitrogen or air were blown through these inserts. It is shown that the ablation rate is higher for a swirled film than for a film without swirl, indicating significant enhancement of mass transfer upon swirling of the peripheral flow.
