What is it about?
It is the first time that the flow around a surface mounted cylinder is studied at relatively low Reynolds number up to the onset of instabilities and transition to turbulent flow. Images of three dimensional flow are shown that help understand how the flow develops from its inception up to instabilities. The numerical experiment has been conducted by directly solving the Navier Stokes equations with a home made code.

Why is it important?
This is a fundamental flow in fluid mechanics with numerous applications that may be also used for benchmark purposes. It is important to have a data base for this flow as is the case for other fundamental flows. This work does exactly that; it provides the first and complete data base for this three dimensional flow up to the onset of instabilities.
Perspectives
This work is going to be cited by all workers in the field of three dimensional flows in general and in the field of three dimensional theory of separation in particular, since it provides actual critical points of the flow and how they develop as the Reynolds number increases. This work may serve as a prototype as to how to study other fundamental three dimensional flows.
