Yes. Sort of. In the past, I created a new material (Define->Materials...) with unity viscosity and density equal to the desired Reynolds number. Then, generate the grid nondimensionally and that is it.

It gets harder if there is heat transfer involved, but I guess you could do the same thing.

Thank you for answer

Please can you explain the manner in detailed How can I defin the governing equations in nondimensional form and how can I define the values of properties

Thanks

I don't think I understand you - what do you mean? Actually, I should also check that I remember correctly what I did. I'll do that tomorrow, but you should keep in mind that this is not really a standard use of Fluent, and it shouldn't make any difference anyway.
