Fluid Mechanics Course 🔢 Dimensional Analysis & Similitude
🔒

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
