摘要
采用二维轴对称双温度化学非平衡(2T-NCE)模型,模拟了带有水冷约束管的大气压直流电弧氩等离子体发生器。得出了不同工作参数下等离子体中电子温度、重粒子温度的变化关系,表明直流电弧等离子体有很强的非平衡特性,且变化规律十分明显。
To a better understanding of non-equilibrium characteristics of DC arc plasma,a two-dimensional axisymmetric two-temperature chemical non-equilibrium（2T-NCE） model is applied for direct current arc argon plasma generator with water-cooled constrictor at atmospheric pressure.The results show that the electron temperature and heavy particle temperature has a relationship under different working parameters,indicating that DC arc plasma has a strong non-equilibrium characteristic,and the variation is obvious.
