5.4.2.3. Computational Fluid Dynamics

Try these first

1. 1.

   What is a system in fluid mechanics?

   Hint

   Think about quantities of fluids we study.

2. 2.

   Give an example of a control volume.

   Hint

   Consider any defined area through which fluid moves.

3. 3.

   What defines a control volume in fluid mechanics?

   • A fixed mass of fluid
   • A defined space where fluid flows in and out
   • A theoretical model

   Hint

   Think about how we define areas for analyzing fluid movement.

4. 4.

   True or False: Computational methods are used primarily for very simple fluid flow problems.

   • True
   • False

   Hint

   Consider the complexity of issues where computational methods shine.

5. 5.

   A weather radar tower is subjected to wind speeds reaching 150 km/hr. Using both experimental and computational methods, outline the steps to determine the maximum drag force acting on the tower.

   Hint

   Consider how real and simulated environments affect your analysis.

6. 6.

   Explain how you would set up a control volume for a flow problem involving a submerged object in a fluid. Discuss boundary conditions and assumptions you might apply.

   Hint

   Think about the forces acting on your submerged object and how they interact with the defined volume.
