摘要
本文介绍一种为环形燃烧室提供油蒸汽的蒸发室。研究表明 ,均匀开孔的蒸发室的最初几排孔的喷汽量较少 ,使得位于这些孔后的燃气温度较低。后几排孔的蒸发率接近 1 0 0 % ,喷汽量与开孔面积成正比。增大最初几排孔的面积 。
An evaporator fitted on a model combustor is investigated to provide uniform circumferential gas temperature profile.It is shown that less fuel vapor exhausts from the primary holes with uniform outlet area along the evaporator,so that the lower gas temperature is behind these holes,and the more vapor from the final holes makes the gas temperature higher.The vapor flow is proportional to the outlet area as the evaporativity is 100% for the final holes.Uniform vapor flow and uniform circumferential temperature profile can be achieved with larger primary outlet holes and even final holes.
