5.6. Practical Examples in CFD

Try these first

1. 1.

   What is a stream function?

   Hint

   Think about how we visualize fluid movement.

2. 2.

   What software is commonly used for CFD simulations?

   Hint

   Recall the software mentioned in class.

3. 3.

   What does a stream function represent?

   • Fluid velocity only
   • Flow paths of fluid particles
   • Pressure distribution

   Hint

   Consider the role of the function in fluid dynamics.

4. 4.

   True or False: Mass conservation states that mass can change in a closed system.

   • True
   • False

   Hint

   Think about the conservation laws in physics.

5. 5.

   Calculate the velocity components from a given stream function expressed as psi(x, y) = xy^2.

   Hint

   Don't forget to differentiate appropriately.

6. 6.

   Simulate compressible flow using ANSYS Fluent with specified parameters, analyze the resulting velocity profiles.

   Hint

   Find correlations between parameters and fluid properties.
