Summary (AI generated)

In this analysis, we examine both cavitation and separation constraints, drawing on our previous work in this area. Our optimization process effectively eliminates cavitation and separation issues. Initially, we identified a hotspot at the intersection, but through careful shaping of the airfoil in this region, we successfully mitigated the problem.

To conclude, I want to emphasize that the advancements we achieved would not have been possible without the pioneering adjoint method developed by President Anthony Jameson. I am fortunate to have learned from his work. Throughout his career, he demonstrated a commitment to integrating theory with practical implementation, developing code that is applicable in industrial contexts and making a significant impact on the industry.
