A modified homogeneous flow model was introduced to calculate the flow field in RH degasser,thus getting rid of some earlier methods that are unavailable to be generalized,such as reducing the computation region or presetting the distribution of gas volume fraction.

分别对有、无旋转磁场作用时的RH系统进行了模拟计算。模拟结果表明：流场和脱碳过程与现有文献中实验结果相符合；当旋转磁场作用后，磁感应强度为0.04 T时，初期脱碳速度比无旋流作用时增加了约15%，这是由于旋流增加了系统的搅拌能，提高了脱碳反应速率。

The flowfield and performance of a centrifugal compressor was predicted and analysed, which was composed of a Krain's impeller and two types of vaneless diffuser specially: one was constant area vaneless diffuser and the other was the straight-wall. The results show that the efficiency of the straight-wall vaneless diffuser is obviously lower than that of the constant area, and a separate flow occurs nearby the exit of the centrifugal impeller with the straight-wall diffuser. However, the type of vaneless diffuser has little influence on the aerodynamics performance of the centrifugal impeller. Finally, it is suggested that the constant-area vaneless diffuser should be selected as the downstream extended area of the centrifugal impeller during the prediction for the centrifugal impeller.

对Krain叶轮后带等面积与直壁两种形式的无叶扩压器离心压缩机内部流场进行了计算与分析，结果表明：直壁型无叶扩压器离心压缩机的效率低于等面积无叶扩压器离心压缩机的效率；直壁型无叶扩压器使得叶轮出口的流动出现分离；扩压器的形式对离心叶轮的整体气动性能影响并不大；在进行离心叶轮数值研究时，叶轮后的延伸区最好采用等面积无叶扩压器，以尽量减小无叶扩压器所引起的计算误差。
