摘要
Temperature and radiation properties of I-8MW heat release rate methane/air jet diffusion flames without and with the addition of liquid water suppressant to the fuel stream are studied. The analysis includes an existing parabolic flow solver, in conjunction with the locally homogeneous flow approximation and the laminar flamelet concept. State relationships for methane + liquid water mixtures are calculated from species concentration measurements for methane flames without water added. The analyses are compared with previously published data. Tests for flames without water addition show the applicability of the analyses to the present flame scales. The results for flames with water addition indicate that finite rates of evaporation and separated flow effects need to be considered for accurate predictions at high water loading. © 1991, Taylor & Francis Group, LLC.
