9.3. Experimental Facilities Overview

Try these first

1. 1.

   Define Particle Image Velocimetry.

   Hint

   Think about how light helps visualize the flow.

2. 2.

   What is vorticity?

   Hint

   Consider how rotation happens in fluids.

3. 3.

   What does PIV stand for?

   • Particle Image Visualization
   • Particle Image Velocimetry
   • Particle Induced Viscosity

   Hint

   Remember the technique that uses lasers.

4. 4.

   True or False: CFD can only be used for liquid flows.

   • True
   • False

   Hint

   Think about different states of matter.

5. 5.

   Design an experiment using PIV to study the effects of varying fluid densities on vortex formations in a tank. Include necessary equipment and expected outcomes.

   Hint

   Consider how light interacts with varying media.

6. 6.

   Create a comparison between results obtained through CFD simulations and physical experiments in terms of accuracy and efficiency. Discuss potential discrepancies.

   Hint

   Think about trade-offs between theoretical and practical solutions.
