rotating cylinder
Figure 3-3. A illustrates uniform circulation. B illustrates the increased airflow over the top of a rotating cylinder. The airflow speed is
further increased when the rotating cylinder is in a moving stream of air (C). The air molecules near the surface of an object are slowed
and almost stationary. D is an example of typical aircraft grade aluminum used in aircraft construction to include wings and leading
edges of wings as shown in E (left). When magnified at 1,500x (E, right), polished aluminum is visibly rough. This demonstrates why
airflow is affected by molecular irregularities of the surface.
