Hi to all

I was asked this question but I didn't recieve enough answer Please to whom have information to answer me.

How can I work in non dimensional form in fluent (including non dimensional governing equations and Boundary conditions )to simulate the flow and heat transfer in microchannel

Thanks alot

Fluent is solving NS eqs in dimensional way. The one way would be to modify fluid properties to have specific let say Gr, Pr etc... Having it solved you could use UDM to convert your velocity, temperature profiles to non-dimensional form using reference values and save it to file.

Thank you Tomasz

But how can I inter the properties of fluid and solid to the fluent

thank you again
