摘要
采用ｋ－ε双方程湍流模型对分级机内腔的气流场进行数值计算， 并将数值计算结果与五孔球形探针的测量结果相比较。绘制分级机内腔气流场中三维速度、压力分布的数值计算结果与五孔球形探针测量结果的比较图谱， 两者结果吻合较好。
The centrifugal superfine air classifier flow fields were predicted by the k ε turbulence model developed for CFD(Computational Fluid Dynamics).The velocity fields and static pressure field predicted by PHOENICS are compared to relative components measured by 5 hole probe.The prediction results showed good agreement with experimental data.
