Week 8: Literature review - RANS derivation and analysis

Apply reynold's decomposition to the NS equations and come up with the expression for reynold's stress.

• Explain your understanding of the terms reynold's stress
• What is turbulent viscosity? How is it different from molecular viscosity?

You can do this using pen and paper but while uploading it on the challenge page write all equations using MS word or directly write in the challenge page as there is an option provided to you to insert symbols and equations.

Don't post the snapshot of the page on which you did pen and paper calculation.
