Question 1.
Define Reynolds Decomposition.
Show hintHide hint
Focus on the average vs. instantaneous aspect.
Question 2.
What are Reynolds stresses?
Show hintHide hint
Think about how turbulence impacts flow.
3Question 3.
What does Reynolds decomposition do?
- Separates mean and fluctuation
- Calculates pressure
- Models incompressible flow
Show hintHide hint
Think about how it aids in understanding fluid dynamics.
4Question 4.
True or False: Reynolds stresses are only relevant for laminar flows.
- True
- False
Show hintHide hint
Recall the application of RANS in turbulent regimes.
Question 5.
Consider an airflow over a wing section. Derive the RANS equations focusing on how fluctuations develop and impact the flow, including Reynolds stresses.
Show hintHide hint
Break down the process – emphasize the importance of each term in relation to turbulence modeling.
Question 6.
Analyze a proposed design for a hydraulic structure using RANS equations. Discuss the potential limitations and how they can be addressed in practice.
Show hintHide hint
Reflect on practical experiences in engineering contexts – think of real-world applications.
