| Abstract | The shapes 0umtnous flame boundaries) of steady uonbuoyant round Insninom hydrocarbon-fueled inndna_Jot diffusion flames burning in teflowlng air were studied both experimentally and theoretical]}'. Flame shapes were mea._tred from photographs of flames burning at low pressure in order to minimize the effects of buoyancy. Test conditions involved acetylene-, prepylane- and 1,3-1mtadlene-fueled flt.m_ having initial reactant temperatures of 300 K, ambiant prtssmms of 19--.$0 kPa, jet.ยข_dt Reynolds numbere of 18-121, mad initial air/fuel velocity rifle* of 0.22---32,45 to yield inmineus flame lengths of 21-108 ram. The present flames were dose to the laminar smage point but were not soot emitting. Simple expre_ions to estimate the shapes of Immbuoymat laminar-jet dlffusim Illumes _n coflew were fuuad by exteadlng an eorher analysis of Mshaliapm et aL (Mahaiingam, S. Fer2iger, J.
