This analysis its completely representative and educational :

The external flow CFD analysis are commonly used to study the behavior of objects submerged in continuous non static fluids, it aims to determine how efficiently a body can move throw the medium and how they affect each other in the process.

Here the fluid it's no confined between wall type conditions such as pipes or confined flow cases, the fluid its free to move around the object and interact only with its external "wet" layer, this means that there is the flow involving the body shape what must be analyzed not the core.

Evaluating the pressure distribution on the structure generated by the resistances of the fluid the engineers can optimize the design to decrease the amount of energy needed to move the body or the disturb impact on the fluid patch that leaves the pass of the structure.
