 note = {Operating pressure has been increased up to 25-30 kg/cm2 in the combustors which are recently developed for fan jet engines. The development of the high pressure com- bustors involves many complicated problems to be solved. An important problem among them is fuel dispersion in a combustor. The precent study is on the characteristics of fuel dispersion in high pressure flows.  An experimental study on the spray dispersion was carried out by changing the ambient air pressure Pa of the swirl atomizers. Water was injected in still pressurized air and also in swirled flowfield by the atomizers. The pressure difference JP across the atomizers ranged from 5 to 40kg/cm2 and the ambient air pressure Pa ranged from 0 to 40 kg/cm2G.  The results show that the spray dispersion of each atomizer decreases by increasing the value of 41P-Pa'. The shape of the spray sheath in swirled air flowfield be comes stable, unstable and quasi-stiable, depending on the injected momentum fluxes of spray and swirled flow., 資料番号: NALTM0253000, レポート番号: NAL TM-253},
