摘要
在k-ε双方程紊流模型基础上,结合混合有限分析交错网格法,对流动环境中的同轴纯射流进行了计算,将计算结果与前人的试验资料进行对比,两者吻合较好,表明建立的湍流数学模型及计算方法是有效的。在此基础上,对流速比较小工况时的情形进行预报,并给出同轴纯射流的浓度沿程分布图。
The κ-ε model was used to establish a mathematical model of non-buoyant jet in coflow by using the hybrid finite analytic＇method （FAM）. The comparison result between the simulation and former experimental data is satisfactory, which indicates that the turbulence mathematical model and the numerical method are effective. The prediction results under condition of low velocity and the concentration trajectories of non-buoyant jet were given subsequently.
