Fundamentals of Turbulence and modeling

ME 69700 / 3 (3 Class) Cr.

This course consists of three parts: (i) fundamentals of turbulence including turbulence concepts, statistical description, and Kolmogorov hypothesis. (ii) major modeling concepts and formulations such as direct numerical simulation (DNS), large eddy numerical simulation (LES), and Reynolds averaged Navier-stokes simulation (RANS). Team projects related to turbulence modeling and computation with applications in environment, industry, biomechanics for visualizing and experiencing turbulence.

Textbooks

Outcomes

Upon completion of the course, students are expected to be able to

1. build up a sound background in the mathematical, physical, and statistical description of turbulence

2. apply Komogorov theory to quantitatively predict turbulence scales  

4. derive governing equations for kinetic energy, vorticity, pressure, etc. from Navier-Stokes equation and apply them to non-complicated turbulence

5. apply major modeling tools to turbulence computation at different Re numbers.

6. numerically analyze turbulence properties for decaying isotropic turbulence with and without rotation, turbulent rectangular jets, biological flows in the presence of turbulence etc. through provided computation output data.
