Hypothesis
Can a fish scale structure reduce pressure loss and suppress corner separation in compressor cascades?
Conclusion
The fish scale structure reduces total pressure loss at the outlet by 3.5% and decreases the volume of low-energy fluid by 18.36%.
Supporting Evidence
- The fish scale structure effectively reduces the volume of low-energy fluid by 18.36%.
- The total pressure loss at the outlet decreases by 3.5%.
- The AVD iso-surface helps identify low-energy fluid regions.
Takeaway
This study shows that adding fish scales to a compressor can help it work better by reducing drag and improving airflow.
Methodology
CFD simulations were used to analyze the effects of the fish scale structure on flow performance in compressor cascades.
