Hello all,

I want to analyze flow in a microchannel with porous walls and I am doing this using Ansys Fluent. I have come across several articles who have described using the same model ( see attached picture- model ) but unfortunately, none of the Ansys fluent models directly corresponds to the one mentioned.

One possibility was to use a physical velocity model and input equivalent values. I tried to follow this approach but my pressure drop is coming much higher than mentioned in the articles. The strange part is I was able to validate the analytical model of pressure drop ( darcy + inertia ) where a porous medium is placed in the flow path.

I am a bit lost for this validation and any leads in this regard would be really helpful.

Thanks
