viscous validation cases
 

Dear all,

I implemented in a finite volume code full implicit and imex semi-implicit schemes for the NS equations at present without any turbulence model. I am looking for 2D/3D laminar viscous validation cases, apart from circular cylinder and flat plate that would show the gain of implicit time integration, especially for imex. Any idea will be greatly appreciated !

Cheers

This is an exact solution https://pdfs.semanticscholar.org/434...00ac52c18e.pdf

I suggest to simulate also the backward facing-step and the lid-driven cavity as wall-bounded laminar flows

Thank you FDenaro for these suggestions. I forgot to mention that I am dealing with the compressible NSE, so I think the lid-driven cavity test would be difficult without preconditionning.

Search for wind turbine cases
 

Search for low Reynolds number wind turbine airfoil case, that may laminar. Hoping that you are working on Preconditioned solver or a compressible solver that can work on mach 0.1.

laminar flows are characterized by low Re number and that often implies low Mach number, without preconditioning the system is difficult to solve any of these cases

I see, it makes sense. No chance to find a realistic transonic case in laminar regime I guess. Thank you for your answers :)

Well, some special airfoil profile have laminar design (at moderate Mach number)..You could try to search for some database...
