5.6.1. Scaled Models and Wind Tunnel Testing

Try these first

1. 1.

   What is the purpose of a control volume in fluid mechanics?

   Hint

   Think about the area defined for studying fluid.

2. 2.

   What is a scaled model?

   Hint

   Consider what you do in experiments.

3. 3.

   What defines a control volume in fluid mechanics?

   • A fixed mass of fluid
   • A defined region for analysis
   • An unbounded space

   Hint

   Remember the focus of analysis.

4. 4.

   True or False: Scaled models can help simulate real-world fluid dynamics for testing.

   • True
   • False

   Hint

   Think about how testing is performed.

5. 5.

   Using a scaled model, calculate the expected drag force on a weather radar tower with specific wind conditions. Provide steps and rationale.

   Hint

   Think about the relevant equations linking pressure and drag.

6. 6.

   Design a study to test the lift force acting on an aircraft wing using CFD. Outline your methodology.

   Hint

   Consider how the shapes and flow characteristics will simulate actual conditions.
