2.5.2.1. Common Discretization Techniques

Try these first

1. 1.

   What is discretization?

   Hint

   Think about how real numbers can be approximated.

2. 2.

   Define the Finite Volume Method.

   Hint

   Consider its relation to fluid flow principles.

3. 3.

   What is the primary focus of the finite difference method?

   • Control volumes
   • Grid points
   • Elements

   Hint

   Consider the way functions are represented.

4. 4.

   True or False: The finite element method is suitable for simple geometries only.

   • True
   • False

   Hint

   Think about the method’s capability.

5. 5.

   Consider a fluid flowing through a complex pipeline system. Propose a discretization method and justify your choice.

   Hint

   Reflect on how geometry impacts your method choice.

6. 6.

   You are tasked with simulating flow over an aircraft wing. Discuss which technique you would use and the factors influencing your decision.

   Hint

   Consider conservation aspects that are critical in such simulations.
