2.4. Differential Equations of Fluid Flow

Try these first

1. 1.

   What does the Continuity Equation represent?

   Hint

   Think about what happens to mass in a closed system.

2. 2.

   Name one turbulence model.

   Hint

   These are common models used for turbulent flow.

3. 3.

   What does the Continuity Equation ensure?

   • Energy Conservation
   • Mass Conservation
   • Momentum Conservation

   Hint

   Think of how mass behaves in fluids.

4. 4.

   True or False: The Navier-Stokes Equation can only model laminar flows.

   • True
   • False

   Hint

   Recall the types of flows we've discussed.

5. 5.

   Given a pipe with varying cross-sectional areas, describe how the Continuity Equation applies when the flow speeds change. Explain how to calculate the flow rate.

   Hint

   Consider the pipe's cross-section shapes.

6. 6.

   A CFD model predicts turbulence using Reynolds Averaged Navier-Stokes equations. How do you approach validating this model against experimental data?

   Hint

   Review validation procedures in CFD studies.
