   What is CFD primarily concerned with?

   • Analyzing structural integrity
   • Predicting fluid flow
   • Calculating thermal effects

   Hint

   Think about what domain CFD operates within.

4. 4.

   True or False: Turbulent flow is always easier to analyze than laminar flow.

   • True
   • False

   Hint

   Reflect on the nature of complications in fluid movements.

5. 5.

   Describe the impact of grid size on the accuracy of simulations in CFD. Provide examples of how changing the grid size can affect results.

   Hint

   Consider how close approximations lead to improved results.

6. 6.

   Discuss how the choice between direct numerical simulation and Reynolds-averaged Navier-Stokes equations affects computational demands and accuracy.

   Hint

   Think about cost versus benefits in computational strategies.
