摘要

为了研究入口燃气参数对含导流片及钝体的驻涡燃烧室性能的影响,改变不同进口温度、进口速度以及当量比等,对驻涡燃烧室进行了数值模拟。结果表明:较高的进口温度以及较低的进口速度都能有效的降低燃烧室总压损失,当量比的改变对总压损失影响不大;燃烧室在贫油条件下的燃烧效率要比富油条件下的要高,当量比小于或等于1时,燃烧室的燃烧效率能达到99.8%;入口参数的改变对出口温度分布都有所影响,OTDF的值大体在0.06~0.1之间。

Abstract

To investigate a trapped-vortex combustor with guide vane and bluff body, different inlet temperature, velocity and equivalence ratio had been changed to study the performance of this combustor. The results show that high inlet temperature and low velocity can reduce the total pressure loss, the change of equivalence ratio has little impact on total pressure loss. Combustor performance of lean oil condition is better than rich oil condition, when the equivalence ratio is less than 1, the combustion efficiency will reach over 99.8%. Each entrance parameters' change can influence the outlet temperature distribution, the OTDF is between 0.06~0.1 in various working conditions.

Key words： guide vane; bluff body; trapped vortex combustor; numerical simulation
