Slides #8 (2019)

Recognizing turbulence, The effects of turbulence, Quantifying turbulence, Computing turbulence, Commented bibliography

Scale flows and measurements up and down to facilitate observation

Comparing influcences: the weighted momentum balance; Making models; Comparing results: force and power coefficients.

Understand when flows follow walls, and quantify shear on walls when they do

Model flows at two extreme ends of the size spectrum

Flow at large scales; Plotting velocity with functions; Flow at very small scales.

The next exam will take place on July 11, 2019.
