Numerical Study on the Unsteady Flow in the Vaned Diffuser of Centrifugal Compressor
- 발행 : 2001.11.01
초록
Interaction of flow through an Impeller and a Vaned Diffuser in Centrifugal Compressor was investigated using the 3-dimensional Wavier-Stokes solution method. To consider the interaction effect of impeller and vaned diffuser, Inlet boundary conditions are imposed with the results of the steady calculation of the impeller and rotates with time. The results have been compared to steady computation results and experiment. From this, it is discussed about the compatability of the method and the advantage and disadvantage of the steady calculation.
