Hagen Poiseuille flow in circular micro-ducts
 

Hi all,

I am trying to simulate low-speed pressure driven flow of a non newtonian fluid in micro duct using GAMBIT 2.4.6 and FLUENT 6.3.21. I have used GAMBIT and FLUENT before for cases like flow over a cylinder, but I am clueless as to how to go about this problem.

I have created a 3D axisymmetric model in UG and exported the file to GAMBIT for meshing. I need to know how to go about meshing the model and using the correct solver for eg density based or pressure based.

I also found out that since this a case of laminar flow, the boundary layer would be play an important role and thus the way its mesh.

Any help would be greatly appreciated.

Thanks,
Anup
