摘要
采用激光多谱勒测速仪对小流量发动机短环直流燃烧室的流场进行测试,并且在三维任意曲线坐标系下对该燃烧室流场进行了数值模拟。通过试验结果和计算结果的对比可以看出,两者在燃烧室出口符合较好,表明流场计算程序是可靠的,为了全面地反映燃烧室中的真实流动状况,对燃烧室和旋流器的流场进行整体计算。
A swirling flowfield inside a sector annular combustor is measured by Laser Doppler Velocimeter (LDV) and calculated by SIMPLEC algorithm on arbitrary three-dimensional curvilinear coordinates. The comparison between experimental and calculational results shows that the results agree well with that in exit of combustor, and so the numerical procedure is reliable. It is necessary to calculate the whole flowfield of the combustor and swirler for real flow situation in combustor.
