Improved Design for Welding Exhaust Volute after Tandem Cascade |
| |
| Abstract: | The numerical simulation on the testing equipment of a stage in assembled centrifugal compressor is carried out. Several projects for exhaust volute with different welding types are designed based on the analysis of original structure and flow field of model stage. A more ideal project for exhaust volute with welding type is obtained through comparison and analysis and the stage efficiency has been improved about 4%. |
