Numerical calculation was conducted to obtain the optimum structure parameters of the trapped vortex combustor (TVC) with the guide vane and blunt body. The results show that the optimum structure parameters of the guide vane are , , and , and the optimum structure parameters of blunt body are , , and . Then, the influence of different inlet conditions on the combustion turbulence flow was studied. The results show that high inlet temperature and low inlet velocity can effectively reduce total pressure loss; the equivalence ratio has little effect on total pressure loss. The study of unsteady flow shows that double vortices undergo the process of preliminarily forming-breaking down-forming again-being stable gradually.

带有导向叶片和钝体的截留涡流燃烧室中的燃烧湍流

进行了数值计算，以得到带有导向叶片和钝体的涡流燃烧器的最佳结构参数。结果表明，导叶的最佳结构参数为， ，和，钝体的最佳结构参数为， ，和。然后，研究了不同进气条件对燃烧湍流的影响。结果表明，较高的进气温度和较低的进气速度可以有效地减少总压力损失。当量比对总压力损失影响很小。对非定常流动的研究表明，双旋涡经历了初步形成-分解-再形成-逐渐稳定的过程。
