Similitude & Model Testing
Inside this lesson
- Define geometric, kinematic, and dynamic similarity and explain how they depend on one another
- Apply Froude scaling to a ship model: derive model speed and prototype force from the length scale
- Apply Reynolds scaling to pipe or wind-tunnel flow and explain why it conflicts with Froude scaling
- Explain why complete similarity is often impossible and describe the engineering strategy for choosing which dimensionless group to match
