11.1.3. Flow Visualizations

Try these first

1. 1.

   What are streamlines?

   Hint

   Think about how a river flows.

2. 2.

   What type of experiments can be conducted with the Hele-Shaw apparatus?

   Hint

   Consider what happens when a solid object is placed in water.

3. 3.

   What is the purpose of flow visualization?

   • To predict weather patterns
   • To understand fluid behavior
   • To create obstacles

   Hint

   Think about how we learn about rivers.

4. 4.

   True or False: A streamline can change its shape during fluid flow.

   • True
   • False

   Hint

   Consider what a streamline means.

5. 5.

   Design an experiment using the Hele-Shaw apparatus to visualize the effects of changing flow speeds on vortex formation.

   Hint

   What do you think happens when you speed up or slow down the water?

6. 6.

   Using CFD software, simulate a scenario where fluid flows around a circular obstacle. Analyze the results and interpret the flow pattern.

   Hint

   Think about how the obstacle alters the flow.
