where a mapping procedure is carried out between to planes with a given offset between them. The profile from the interior plane is mapped back on to the inlet, hence between these two planes you basically have an infinitely long pipe, and since you are considering laminar flows, then the distance between the two planes is of minor importance as far as the validity of the velocity (and turbulence) profile(s) goes.

I have some nice pictures of a laminar jet in a laminar cross flow on which I performed a POD-analysis, so if you are interested in seeing the results just drop me an email.

Happy New Year,

Niels
