将基于重整化群理论的ε方程与张健等提出的新代数应力模型（ＮＡＳＭ） 相结合，提出了重整化群代数应力模型（ＲＮＧＡＳＭ） 。同时运用Ｋε模型、ＮＡＳＭ 模型和ＲＮＧＡＳＭ 模型计算了强旋转受限射流，较为准确地预报了强旋转受限射流的回流区、轴向速度和切向速度，给出了６ 个湍流应力的分布，显示了强旋转受限射流流场的各向异性特点，同时对不同旋流强度的旋转流场进行计算。其结果与实验值吻合得较好，改善了新代数应力模型的不足之处 The renormalization group algebraic stress model (RNGASM) is proposed based on the ε equation of renormalization group theory and the new algebraic stress model proposed by Zhang et al. (NASM). At the same time, the constrained jets with strong rotation were calculated by using Kε model, NASM model and RNGASM model, and the recirculation zone, axial velocity and tangential velocity of the confined jets with strong rotation were predicted accurately. The distribution of turbulent stress shows the anisotropic characteristics of the turbulent flow field and the rotational flow field with different swirling intensities. The result is in good agreement with the experimental data, which improves the shortcomings of the new algebraic stress model
