5.2. Introduction to Flow Analysis

Try these first

1. 1.

   What is the difference between a system and a control volume?

   Hint

   Think about boundaries and flow.

2. 2.

   Name one technique used to visualize fluid flow.

   Hint

   Consider how we observe the flow.

3. 3.

   What characterizes a system in fluid mechanics?

   • A dynamic space
   • A fixed quantity of fluid
   • An empty volume

   Hint

   Recall basic definitions.

4. 4.

   True or False: Control volumes cannot interact with their surroundings.

   • True
   • False

   Hint

   Think about flow movement.

5. 5.

   Design a simple experimental setup to measure drag force on a small model of a bird in a wind tunnel. Describe what equipment you would use and how you would collect data.

   Hint

   Consider how you'd measure airflow around the model.

6. 6.

   How could you incorporate computational fluid dynamics to analyze a new design for a wind turbine? Discuss the steps and considerations you'd take in modeling the fluid flow around the turbine blades.

   Hint

   Think about the significance of turbulence modeling.
