1. Efficiency vs Flow Rate Plot (efficiency_flow_plot.png)

• Shows the relationship between flow rate and efficiency
• Points are colored by test case category (Low, Medium, High flow rates)
• Includes trend line to show overall efficiency pattern
• Highlights the efficiency drop at 35 m/s

2. Convergence Plot (convergence_plot.png)

• Displays optimization improvement for each flow rate
• Separate lines for each test case
• Shows how quickly each case converged to optimal solution
• Helps identify challenging operating points

3. Performance Heatmap (performance_heatmap.png)

• 2D visualization of performance density
• Bright regions indicate optimal operating conditions
• Red points show actual test points
• Helps identify stable operating regions

4. Interactive Analysis (interactive_analysis.html)

Interactive dashboard with four panels:

2. Optimization Improvement: Shows convergence patterns
3. Error Distribution: Histogram of optimization errors
4. Performance Overview: Bar chart of average efficiency by case

Key Visualization Insights

1. Operating Range Performance:

   • Clear efficiency plateau in medium flow range (15-30 m/s)
   • Sharp efficiency drop at 35 m/s
   • Recovery of efficiency at 40 m/s

2. Optimization Effectiveness:

   • Most test points achieved perfect convergence
   • Low flow rates show some residual error
   • High flow rates demonstrate stable convergence

3. Performance Stability:

   • Most stable performance in medium flow range
   • Higher variability at flow extremes
