What is common about the fluid flow in the following video?
The fluid flow over any solid body immersed in it is commonly referred to as an external flow. In this case, the flow over an airplane, around the person sky-diving or sprinting, or even around a reentry capsule which is entering the Earth's atmosphere, are all examples of fluid flows. In this section, we will understand the fundamentals of external fluid flows.
Here are the corresponding handout slides for this lesson.
