Test for a laminar flow in axisymmetric nozzle

Victor

Hello everyone, I am looking for a valid test case for a viscous laminar flow into an axisymmetric nozzle. It doesn't matter whether compressible or incompressible as long as it is subsonic. Possibly something with separation in the divergent region, and which doesn't require multibclok geometries; I need to validate the coordinate tranformations I implemented in the code. I am sure there is something available on the WEB, but where? Thank you
