4 cards from this section. Quick, good the night before a test.
What does Reynolds shear stress represent?
Think about turbulence and stresses in fluids.
Define turbulent kinetic energy in your own words.
How do turbulence and energy relate?
What is the primary purpose of the Reynolds number in fluid dynamics?
Remember its relation to inertial and viscous forces.
True or False: The closure problem indicates that we must add more equations to model turbulence accurately.
Think back to how we model turbulent flows.
Design a simulation setup for airflow in a ventilated room. Discuss how you would select the grid size based on turbulence and what models you would use.
Consider practical examples like HVAC systems.
Explain how increasing the Reynolds number affects the turbulence modeling strategy in CFD.
Reflect on the flow characteristics and their relation to Reynolds number.
