摘要
通过数值计算的方法对可控活化热氛围燃烧器的速度场进行了数值模拟.通过实验验证了模型,进而分析了中央射流速度、协流速度和温度对燃烧器速度场的影响,并结合温度场稳定区域范围的变化曲线,分析了此活化热氛围燃烧器的适用性.研究表明,增大中央射流速度、协流速度和温度都会使速度场势核区范围扩大,其中中央射流速度的增大量会受温度场稳定区域范围的限制,但可以通过增大协流速度来解决这一矛盾.
This paper presented the study on the velocity field of a controllable active thermo-atmosphere combustor （CATAC）, and the influence of the velocity and temperature of co-flow and the velocity of jet flow on the velocity field of CATAC. Combined with the results of temperature field, the usability of the CATAC was proved. The research shows that the region of the velocity core can be increased by increasing the velocity of jet flow, co flow or the temperature of co-flow. The increase of the velocity of jet flow will make the ignition take place in wrong temperature, but it will be covered by increasing the velocity of co flow.
