摘要: 在任意曲线转动坐标系及重整化群(RNG)方法改进的k-ε两方程湍流模型基础上,提出了"通用进出口边界条件"的给法,并利用改进的强隐式(MSIP)方法进行计算迭代,提高了对多排叶轮机数值模拟的稳定性和准确性.通过对某对旋轴流风机定常全三维流场的计算,并与设计参数和实验性能参数进行对比分析后,验证了在风扇/压气机的设计中,不宜在叶尖区分配最大负荷,这种设计对对旋轴流压缩系统尤其不利.

Abstract: To enhance the stability and accurate when calculated the complicated turbomachinery rows, an inlet/outlet condition as called general boundary condition and an advanced strongly implicit iterative method named MSIP were presented. Based on rotational arbitrarily curved coordinate and RNG improved k-ε turbulence model, the three-dimensional calculating for a counter-rotating axial fan indicate that it is not appropriate to allocate the maximum load at the blade tip when make an aerodynamic design for axial fan or compressor, especially for counter-rotating system.
