Flow around a sphere and a circular cylinder
 
Hi guys,

I am wondering how relevant is the flow around a sphere and a circular cylinder.

Suppose the same up-coming flow velocity. The flow can pass around the sphere in all directions, but not for a cylinder. Hence, Vs < Vc, and then the momentum on the sphere is smaller. As a result, the flow separates earlier on the sphere.

Does that make sense?

Thanks a lot.
