摘　　要：对燃气轮机燃烧室电弧等离子体点火器内湍流燃烧流场,进行了传热与流动数值模拟。采用了RNGk-ε湍流模型、扩散燃烧模型和离散传播辐射DTRM模型。计算域包括点火器内的等离子体发生器和点火器主体。将计算结果与未考虑辐射的温度场和流场进行了比较。结果表明辐射模型对其温度场有影响,对速度场影响不大;在点火器出口处的径向温度分布是均匀的。The numerical simulation of the heat and turbulence burning flow in the arc-plasma ignition of the gas turbine was carried out, with RNGk -ε turbulence model and diffuse combustion model and discrete transfer radiation DTRM modle. The calculation domain includes the ignition and its arc-plasma generator. The simulate results are analyzed and compared with the no-consided name radiation, The modeling results show that there are effect to the temperature field due to radiation and not half to the speed field. The temperature radial distributing are evenly in the outflux of ignition.
