CFD Analysis of Flow through Compressor Cascade

CFD Analysis of Flow through Compressor Cascade

Abstract— This work aims at analyzing the flow behavior through a compressor cascade with the help of Computational Fluid Dynamics using the FLUENT software. An attempt has been made to study the effect of angle of attack or flow incidence angle on various flow parameters viz. static pressure, dynamic pressure, turbulence and their distribution in the flow field and predict the optimum range of angle of attack based on the above observations. Particularly, two principle parameters viz. the static pressure rise for the compressor cascade and the turbulence kinetic energy are considered in this analysis. It is observed that maintaining a slightly positive angle of flow incidence of +2 to +6 degrees is advantageous.

Panel Discussion on Inducer Design Criteri

Panel Discussion on Inducer Design Criteria

معیار های طراحی ایندیوسر

This article reports a panel discussion titled Inducer Design Criteria presented at the 9th International Symposium on Transport Phenomena and Dynamics of Rotating Machinery (ISROMAC-9). The presentations of the panelists and the subsequent discussions are summarized. It is shown that cavitation instabilities are major problems in modern turbopumps and that design criteria to eliminate them are needed. Available design methods for inducers and marine propellers are reviewed, and new criteria to enhance stability are proposed. The current status of CFD is reviewed and an example of successful application is shown. Discussions of several specific topics are reported and future research needs are noted.
